Product Overview 

 Q941 type electric ball valves in two cut adjust occasions. The connection of the valve with the implementing agencies with Direct Connect, built-in electric actuator servo system, no need to reprovision the servo amplifier, the input 4-20mA signal and 220VAC power supply to control the operation. With the connection is simple, compact, small size, light weight, resistance, action, stable and reliable. Another configuration UNICs, PSQ, HQ, DHL and other models of electronic electric actuator or GTX, AL gas piston executing agency implementing agencies according to user requirements.
