Q947 fixed electric ball valves are suitable for two-digit cut-off and adjustment. The connection between the valve and the actuator adopts the direct connection mode, and the electric actuator has a built-in servo system, which does not need to be equipped with a servo amplifier, and can be controlled by inputting 4-20mA signal and 220VAC power supply. It has the advantages of simple connection, compact structure, small size, light weight, low resistance, stable and reliable operation. The actuator can be equipped with UNIC, PSQ, HQ, DHL and other electronic electric actuators or GTX, AL and other gas-piston actuators according to the requirements of users.
