ZDJR/ZDRO electric O-type cut-off ball valveDetailed product description：

summary:

ZDJR/ZDRO electric O-type cut-off ball valve is suitable for two position cut-off and adjustment applications. The connection between the valve and the actuator adopts a direct connection method. The electric actuator has a built-in servo system and does not require a separate servo amplifier. It can control the operation by inputting a 4-20mA signal and a 220VAC power supply. It has the advantages of simple connection, compact structure, small size, light weight, low resistance, stable and reliable action. The actuator can be configured with electronic electric actuators such as UNIC, PSQ, HQ, DHL, or pneumatic piston actuators such as GTX and AL according to user requirements.
