1. Overview of fixed electric ball valve

 Q947 fixed electric ball valve is suitable for two-position cut-off and adjustment occasions. The connection between the valve and the actuator adopts a direct connection method. The electric actuator has a built-in servo system, and no additional servo amplifier is required. Input 4-20mA signal and 220VAC power supply to control the operation. It has the advantages of simple connection, compact structure, small size, light weight, low resistance, stable and reliable action, etc. The actuator can be equipped with electronic electric actuators such as UNIC, PSQ, HQ, DHL or other pneumatic actuators such as GTX and AL according to user requirements.Second, the implementation standard of fixed electric ball valve
