Combined electric – hydraulic actuor for valve
Model : EHPP-200
General introduction
EHPP is a compact hydraulic drive controller that integrates electric motor, exhaust valve, check valve and hydraulic gear pump inside the actuor. It works with small amounts of liquid and minimizes pressure losses when transmits by increasing responsiveness and simplifying hydraulic pipes. As communication expands not only through RS232 but also RS442/485, it can communicate a wide range of industrial communication types. Therefore, users can control multiple hydraulic power supplies from a distant place according to the specified protocol. And users can track actual activity in real time by responding to the control state of the EHPP-200. Users can also control the EHPP-200 manually (manual control)
Characteristics and features
- Significantly reduce the length of hydraulic pipes
- Easily control valve position and monitor valve opening and closing level
- Removal of heavy, complex equipment
- Easy installation and maintenance
