Description

ZECO Valve is an professional Air Vent Valve manufacturer

What is an Air Vent Valve?

An air vent valve is a safety device that discharges air at the water supply piping in order to avoid air related problems in the water piping systems.

How does an Air Vent Valve work?

When liquid is pumped through the system at startup, the initial air inside the piping is pushed into the air vent by the pressure of the flow. The float remains in the lower part of the air vent, allowing the valve to remain open and continuously discharge air.

After the initial air venting, liquid flows into the air vent. The float rises with the rising liquid and closes the valve.

If air enters the air vent while it is closed, the liquid level drops and the float lowers, allowing the valve to open and discharge air once more.

What are Air Vent Valves used for?

• For protecting piping materials and systems from corrosion due to air (oxygen).
• For preventing water splashing at faucet due to the existence of air.
• For preventing noise resulted from the ingress of air into cold/hot water supply systems, air conditioning systems, and other systems.
• For the smooth startup and stable operation of water supply and other systems/devices through air discharge at the time of initial water conveyance.

Applications of Air Vent Valve

• Cold and hot water supply system
• Hot water boiler
• Solar hot water system
• Other various devices
• Air conditioning system
• Hot water heater appliance
• Pressure tank

Features of Air Vent Valves:

• High Quality: The exhaust mechanism is very reliable and is cast from high-precision components
• Good Feature: This valve features high temperature resistance, rust protection, reliably sealing.
• Exquisite Design: The steam and water separation tray is designed with special structure to ensure that the water will not be discharged during exhaust. As long as the system has pressure, the exhaust valve will continue to vent.
• Convenient: It is convenient to demount and maintenance, while the water in the system will not flow out, so there is no need to empty the system.
• The steam and water separation tray is designed with special structure to ensure that the water will not be discharged during exhaust.
