Explosion Proof Electric Actuator 3 Way Ball Valve
If you need to actuate a 3-way valve in an environment that is not air-conditioned, the best solution is to use an electric actuator. Unlike pneumatic actuators, electric actuators are powered by electricity, which is not subject to dew point (the temperature at which condensation forms in the air).
A double-acting model uses electrical current to move internal pistons, which rotate an actuator pinion that either opens or closes the valve. In the event of power failure, a spring-return failsafe is provided to set the valve into a safe position determined by the operator. This type of actuation is particularly well-suited to industrial applications where a reliable and cost-effective solution is required.
Choosing the right type of electric actuator will depend on your valve type, speed and torque requirements, environmental conditions and regulatory and support requirements. For example, servo motors offer dynamic torque and high control accuracy and stepper motors are better suited for lower-speed applications. Electric actuators are available in explosion-proof and washdown versions to meet various application and environmental needs.
The explosion-proof electric actuator is designed to be used in hazardous environments with flammable liquids or gases such as gasoline, hexane, naphtha, benzene, butane, propane, acetone and lacquer solvent vapors. The actuator features an explosion-proof housing that protects the internal mechanism from ignition of flammable substances. It can be operated remotely, with visual valve position indication and a manual override function, and is suitable for use in flanged connections. Explosion Proof Electric Actuator 3 Way Ball Valve
