Electric flanged ball valve 
 Electric ball valve Q941 

 Product Overview 
 Q941 electric valve for the two cut off, adjust the occasion. Valve and the actuator connected by straight way, the electric actuator servo system built without reprovision servo amplifier, the input 4-20mA control signal and 220VAC power supply to operate. With a simple connection, compact structure, small size, light weight, resistance, stable and reliable operation. Actuator can be configured according to user requirements other UNIC, PSQ, HQ, DHL and other models of electronic or electric actuator GTX, AL and other gas piston actuator.
