How to choose suitable valve drive? Drive Selection basis on the following:
Valve Type, Size, Pressure and Structure
Valve Torque(Pressure difference of pipeline), Push
Max. Temperature of ambient and Flow
Number of Use and Usage
Open time or shut time of Industrial Valve
Diameter of Valve Stem, thread pitch and direction of rotation
Connection Type: Flange end, Butt Weld, Socket Weld or NPT
Supply Power: Electric power, frequency and Phase; Air Supply
Special requirements: Low temperature, water-proof, Fire-Safe, corrosion prevention and anti-explosion.
The electrical actuator valve and diaphragm pneumatic actuator control valve are widely used in industrial field. Motor device is popular used for on-off valve, specially for power plant valve pressured 150LB to 4500LB and also for common industrial valve such as electric actuator gate valve, electric actuator globe valve. Pneumatic device is used for control valve, like pneumatic actuator globe valve, swing check valve with cylinder and pneumatic actuator ball valve. Solenoid operation is suitable for small size forged steel valve size 1/2" to 2".
