Q941F concept:
Q941 type electric ball valve is suitable for two position cut off and adjustment. The connection between the valve and the actuator is directly connected, the electric actuator is built into the servo system, and no need to be equipped with the servo amplifier, the input 4-20mA signal and the 220VAC power supply can control the operation. The utility model has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable action, etc.. According to the requirements of the user can be configured with UNIC, PSQ, HQ, DHL and other models of electronic electric actuator or GTX, AL and other gas piston actuator.
