Features of Pressure Independent Control Valve

• No external energy is required for automatic flow regulation;
• Automatically adjust equipment or pipeline flow to meet the required design flow;
• No need for balance debugging before the system runs;
• Keep pipe flow constant.

PICV Working Principle

When the pressure difference control range is above, the valve tank is completely compressed, the cross-flow area is only the minimum design channel, and the flow rate changes with the pressure difference. When the pressure difference is within the control range, the valve tank moves with the pressure difference, thus changing the flow area and keeping the flow at the set value. Under the pressure differential control range, the valve is fully extended to reveal the maximum overcurrent area, and the flow rate changes with the pressure difference.

PICV Installation and Commissioning

This valve is mainly used for flow regulation and hydraulic balance. It can not be used as a shutoff valve because there is a certain amount of leakage when it is closed. For specific use, please consult Zeco Valve Group.

Pressure Independent Control Valve

Features of Pressure Independent Control Valve

• Flow regulation and hydraulic balance are integrated;
• The self-acting diaphragm differential pressure controller responds quickly to the change of flow rate;
• Reduce the use of air conditioning system valves;
• Improve the efficiency of water pump operation and save energy.

Pressure Independent Control Valve Working Principle

PICV valve keeps ∆P constant through the spring force. The pressure channel inside the valve body will adjust the pressure P1 and P2 at both ends of the structure, causing the upper and lower ends of the diaphragm respectively. The balance state P1=P2+P spring will be maintained through the action of spring force. If P1 increases, the force acting on the lower part of the diaphragm increases correspondingly, and the diaphragm moves upward, reducing the pressure difference control structure space, and P2 increases accordingly to reach a new balance. And vice versa; And PICV valve adjust the flow rate by adjusting the disc to change the Kv value.

What is an Electric Actuated Gate Valve?

Electric actuated gate valve refers to the linear movement of the electric gate valve actuator through electric voltage and signal control to open or close the gate valve. Electric gate valves can help you achieve the purpose of remote control, help you reduce labor costs, and improve production efficiency.

ZECO electric actuated gate valve is a gate valve controlled by an electric actuator. It can operate the gate valve remotely through an electric device, which is usually installed in the upper part of the gate valve. Electric actuators are divided into three, one is a straight stroke: the valve up and down to control the valve opening (such as single seat valve, double seat valve, sleeve valve, Y valve, etc.); The other is a quarter-turn: driven Angle of the valve is in 0 ~ 90 ° rotation to control the valve opening (such as eccentric butterfly valve, ball valve, rotary valve, plug valves, etc.); The last one is multi-turn electric actuators (360 ° Angle >) is suitable for the gate valves, globe valves, etc. Electric actuator output shaft rotation is more than a week, that is greater than 360 °, generally need more than one ring valve opening and closing process control can be achieved. ZECO is a professional manufacturer of electric gate valves, high quality creates ZECO brand.

How does an Electric Actuated Gate Valve work?

Torque is the rotational force an actuator generates to close a rotational valve. Electric actuators can generate this force by transmitting it to the output shaft and then the valve stem. When pressure is applied to the valve stem, the valve’s orifice opens or closes.

What does an Electric Actuated Gate Valve use for?

Electric actuated gate valve is one of the most commonly used cut-off valves, mainly used to connect or cut off the medium in the pipeline, but not suitable for adjusting the flow of the medium. The gate valve is suitable for a wide range of pressure, temperature, and caliber, especially suitable for medium and large-diameter pipelines.

What is a Motorized Butterfly Valve?

A motorized butterfly valve is a type of valve which can be used for isolating or regulating flow. The closing mechanism is the disc, which sits in the center of the valve body. The disc is connected to a handle or actuator via the shaft, which passes from the disc through the top of the valve body.

ZECO motorized butterfly valve is suitable for the occasion of flow regulation. Because the butterfly valve disc and stem components still have the problem of resisting medium flow in the pipeline, the pressure loss of the butterfly valve is still greater than that of the gate valve. Therefore, the influence of pressure loss should be considered when selecting a motorized butterfly valve as the regulating or switching valve. But the structure of the butterfly valve length is short, the overall height will be short many compared to other valves, at the same time open speed by electric, gear or handle faster than many other valve operation, at the same time has good flow control characteristics, so the use of motorized butterfly valve range is very wide, usually as the regulation of motorized valves and motorized switch valve is used in petroleum, chemical industry, power plants, pharmaceutical, shipbuilding, metallurgy, and other industrial areas, at the same time as the pipeline system of the cut-off valve, control valve, and check valve. ZECO, as a professional manufacturer of motorized butterfly valves, usually uses specially designed metal sealed triple eccentric or double eccentric butterfly valves as recommended products for users under special working conditions.

How does a Motorized Butterfly Valve work?

A motorized butterfly valve operates by changing the position of a round disc that is located within a pipeline. The disc is the size of the pipe circumference, which allows it to create a reliable seal during instances when it is necessary to restrict or stop the flow of process media. Motorized butterfly valves are available in a variety of sizes, so any factory will be able to order one that specifically fits and operates within their pipelines. The most common ranges of sizes for butterfly valves and their discs are between a couple of inches and a couple of feet, although larger industrial applications of this particular valve may span quite a bit larger than those typical ranges.

When a motorized butterfly valve disc is in the closed position, the pipeline is completely blocked and flow is stopped. The disc for the valve is attached to the valve shaft, which is then controlled by a motor. When this motor moves the valve to the open position, the disc is parallel to the pipeline and liquids are able to flow past the disc on either side. There is still a drop in flow volume because the disc itself is still present within the pipeline. However, flow is permitted to pass. If flow needs to be throttled, controlled, or regulated for volume as production needs to change, the motor can turn the disc to a position where it is partially open. If a changing amount of process media volume flow is needed for production, the motorized butterfly valve can adjust during the process to supply appropriate amounts of liquid.

Applications of Electrically Actuated Butterfly Valve

Butterfly valves are isolating valves used on water supply networks, in the interconnections of networks, in the factories, in pumping stations, on the general networks, and on the fire protection networks in industrial sites.

What is an Electric Butterfly Valve?

View ZECO range of electrically actuated butterfly valves, which are used to control the flow of a media remotely. They can have either a lug or wafer connection style. The actuator either opens or closes the valve with an electrical current, but doesn’t require energy to stay in that state. The butterfly valve has a disc that rotates with the actuator to open or close the butterfly valve. The butterfly valve design allows for good sealing properties, durability, and reliability for your application. Electrical actuators are easily installed and wired into an existing system. There are various housings, seals, and sizes of electrically controlled butterfly valves to allow you to find the right one for your application.

Good sealing inside the valve will be affected the sealing performance because of the damage or normal abrasion. For the harsh working conditions, the estimation and repairment beyond the scope of this manual, due to a variety of different structural forms, if needed know in advance, should cooperate with the manufacturer to find a suitable method. The external construction of the valve is easy to check and maintain. So a rational approach should be taken to prevent mechanical to damage the valve, prevent valve corrosion by the sediments in the atmosphere、chemical substances or wet gas, and deterioration of its quality. Thread、bearings or gears work like the working interface should be periodic lubrication.

How does an Electric Butterfly Valve work?

A butterfly valve is a valve used for flow regulation in large pipe diameters in which the disc takes the form of a disk. The operation is similar to that of a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

A butterfly valve actuator controls the flow of gas or liquid by means of a disk, which turns on a diametrical axis inside a pipe or by two semicircular plates hinged on a common spindle, which permits flow in only one direction. These actuated butterfly valves offer a rotary stem movement of 90 degrees or less, in a compact design. Unlike ball valves, butterfly valves do not have any pockets in which fluids may become trapped when the valve is closed.

Features of Electric Actuated Butterfly Valve

What is an Motorized ball valve?

The working of an motorized ball valve is similar to its manual counterpart but in this valve, an electric actuator is mounted instead of a lever to drive the stem (which is connected to the ball) which in turn, rotates the ball to provide the desired operation. As the electric actuator receives a signal from remote control location depending on its position it will rotate to start or stop the flow of fluid through the ball valve.

An motorized ball valve can be designed to change positions based on sensor readings. A sensor can detect and report changes in temperature or pressure. The motorized ball valve is triggered when the sensor reaches a predetermined point set by machine management staff. This could perform important functions, such as keeping more process fluid from reaching an area that is already full. When the sensor detects that the area is available for more fluid, it activates the motorized ball valve, which changes position to allow process fluid to reach that location.

How does an Motorized ball valve work?

Motorized ball valves is mainly composed of two parts, namely electric actuator and valve. After certain installation and debugging, the switch of the equipment can be adjusted and controlled normally. The motorized ball valves mainly relies on the motor to drive and execute the operation, the size of the opening can also be adjusted according to the actual situation, so as to control the flow of equipment intermediary, is a very humane operating system.

What are Motorized ball valves used for?

On/Off Control

Motorized ball valves can be switched from open to fully closed without any stops at any position in between. Every time the actuated ball valve finishes the cycle of opening and closing, the electric motor will switch off through internal cams, which strikes the limit switches.

For instance, when the electric motor receives a signal of closing the motorized ball valve, the motor is energized, rotating in order to close the ball valves. Subsequently, the limit switches travel on the cam as the internal cam rotates on the shaft until the lobe makes the switch to stop the electric motor, breaking the circuit.

Positioning Control

Another type of application requires the motorized ball valves to open or close partially, detecting and responding to the various conditions of water flows. In this case, the goal can be achieved through the incorporation of a digital position sensor.

Depending on the special flow requirements, the external control command signal will be created. This input signal will be compared by the actuator of the motorized ball valves consistently to the actual position through the output feedback element. Subsequently, the actuated ball valves will be driven to balance the commands and reach the required position. A signal of approximately 4mA or 0V is typically used to close the motorized ball valves.

Applications of Motorized ball valves

Motorized ball valves introduce into the systems to control valve opening and closing. To measure flow, they are often equipped with gauge monitors or flow meters. Industrial processes, manufacturing factories, chemical handling, food, and beverage equipment, mining operations, power plants, and the energy sector uses actuated ball valves. They’re also used in wastewater treatment, municipal treatment centres, clean water generation, aquariums, aquatics and animal care, chemical production, metals and plating operations, and chemical synthesis.

Features of Motorized ball valves:

1. When medium passes through the valve, the pressure in valve body may possibly push the stem out, or when the valve in repair, if there is pressure in the middle cavity, the stem or medium seems to easily fly out upon disassembling the valve, which can cause injuries to human beings. To prevent these possibilities, a dummy club is placed at the lower part of the stem. In this way, even if there is fire, packing and thrust bearing are burned or packing is damaged due to other causes, the pressure of medium in valve body will make the dummy club of valve stem in close contact with the upper seal face of valve body, thus to prevent medium leaking out from the damaged packing position;
2. ZECO motorized ball valve can be operated remotely, simple and fast;
3. The standard of ZECO motorized ball valve’s electric actuator is AUMA electric actuator. Other types of electric actuators can be selected according to customers’ requirements;
4. ZECO motorized ball valve can choose forged body or cast body, ZECO is very strict in the control of raw materials, no matter what material material can fully meet the requirements of international standards and chemical analysis.
