Technical Parameters of Multi-turn Explosion-proof Electric Knife Gate Valve 

QH Series Mini Electric Explosion-proof Actuator
QH Mini Multi-turn Explosion-proof Actuator

 

Switch-type Actuator (Type A Control Circuit): The switch-type actuator only has a full-open and full-closed limiting position. After receiving appropriate instructions, the actuator will drive the valve to the full-open or full-closed position.

S2 short-time type operating mechanism is adopted. Continuous running time does not exceed 15 minutes.
Feedback-type Actuator (Type B Control Circuit): While driving valve, the actuator sends the valve position signal to the central control system during the whole process.Type B feedback resistance valve position signal.

S2 short-time type operating mechanism is adopted. Continuous running time does not exceed 15 minutes.
Regulating-type Actuator (Type C Control Circuit): A servo controller is installed inside actuator, receives the central control system's instructions to drive the valve to the appropriate opening position according to the changes of controlled variables (flow, pressure, temperature and liquid level) in the pipeline.

S4 intermittent operating mechanism is adopted. Operating frequency per hour can reach 1200 times. Input instructions from the control system
