electro hydraulic actuator,
IP68 220V 240V ZB General electric actuator globe valve 25 - 400Nm
Series ZB Electric Valve Actuators are designed for two position valves and suitable for valves which stems move linearly, such as globe valve, gate valve, throttle valve and diaphragm valve. Combined with a two stage reducer, they can also be used in operating valves which stems move rotating, such as ball valve and butterfly valve.
The torque output from 25N m to 400N m (three aircraft seat), the output speed of a 12, 18, 24, 30, 36, 42, 48, 60 r / mi eight to choose . Manual speed ratio are is 1:1 , we also could provide to rque and thrust the two-connection size, respectively, in line with the standards and JB2920 standard ISO5210. Stroke controller can be expanded to a four position (open, close, mid1 , mid 2 ) . Valve position transmitter (4 ~ 20mA current output) as an annex fo r selection
