Electric Ball Valve

Description

Electric ball valves use an electric actuator to rotate a ball with a hole in the center to control flow.

What is an Electric Ball Valve?

ZECO electric ball valve is named after the combination of an electric actuator and ball valve. It is usually used in medium pipelines requiring remote switch and adjustment control. It is an important control product in industrial automation control. ZECO’s electric actuators are usually equipped with German AUMA electric actuators. If customers have other requirements, ZECO company can also customize them according to customers’ requirements. 2 inch electric ball valve is one of the common types of the electrically operated ball valve.

How does an Electrical Ball Valve work?

Generally, electric ball valves convert the electrical energy into rotary force using the electric motor thus turning ball valves. It is the most efficient mode of controlling valves due to the clean electric energy and quiet mode of turning valves.

To understand it better, here is how the electric ball valve works.

Step One: Powering Up the System

First, you will switch on the electric ball valves to allow the proper flow of electric current through the system. Electric current will power the electric motor which will generate a torque transmitted by a shaft connected to the valve stem.

You will realize that the ball valve begins to rotate due to action from the shaft and the electric motor. The amount of power that you need to control the operations of the electric ball valve will vary accordingly.

You may need 12V, 24V, and 48V of direct current to help in controlling the electric ball valve. On the other hand, you may also use 24V, 48V, 120V, 130V, and 240V of alternating current to control the valve.

Step Two: Controlling the Torque

As the power flow through the motor, you can control the force that the motor will produce to rotate the ball valve. It has a system of different gears which help in controlling the shaft thus producing different levels of force.

You can decide on the gear that will produce the best of forces that can control the electric ball valve accordingly. The speed at which the electric ball valve will operate is inversely proportional to the torque f the electric ball valve.

Features of Electric Ball Valves:

• ZECO is committed to the premise that the products meet international standards, and do its best in the company’s research and development, so as to minimize the cost to users. Therefore, ZECO made great efforts in ball valve torque, and finally developed a product with lower torque than the ball valve on the market, so that it can be equipped with an electric actuator with lower first gear torque to reduce user costs;
• ZECO electric ball valve is available in full size and reduced size series to meet different requirements of customers. Full bore ball valves are provided in the same channel as the inner diameter of the pipeline for minimal fluid resistance and easy pipeline cleaning. The weight of reduced diameter ball valves is only about 70% of the same diameter full bore ball valve, which can effectively reduce the cost and price, while the fluid resistance coefficient is only about 1/7 of the same diameter globe valve;
• ZECO electric actuated ball valve ensures reliable sealing under high, low, and vacuum conditions;
• ZECO electric ball valve with automatic pressure relief structure, when the pipeline pressure abnormal rise, the chamber medium can rely on its own thrust to push the seat and automatic pressure relief.

Applications of Electric Actuated Ball Valves

• Food Service Equipment
• Irrigation Industry
• Vehicle Wash Systems
• Water Treatment Equipment
• Manufacturing Facilities
• Mobile Applications
• Heat Exchangers

How to Install an Electric Ball Valves?

When you’re mounting electric valve actuators in place, use sturdy, industry-standard parts. Many actuators and mounting hardware use the ISO 5211 standards for connections, which ensures various brands and components work together seamlessly.

You’ll need at least three components for mounting:

• An output drive
• A stem to connect to the valve head
• A flange that mounts the actuator onto the valve
• Various actuators require different types of flanges based on the torque and fasteners available.

What Causes Failure in Electrical Ball Valve?

Poor Design of the Electric Ball Valve

You may have a very poor design of the electric ball valve that may fail to work with the application requirements. The poor design may be in terms of poor chemical compatibility, and poor rating on flow or pressure rate.

Faulty Installation

You may also experience failure in successful operations, which may come as a result of poor or faulty installations. There may be leakages or wrong position of the electric ball valves thus leading to their eventual failure.

Improper Operations

In addition to the above contributors, you may also have improper operations for the electric ball valves. In other words, you may use the electric ball valves for the wrong operations thus leading to complete failure.
