HCU Remote

The hydraulic control cabinet HCU Remote is used for remote and local control of valves fitted with hydraulic actuators. The valves can also be operated directly at the cabinet.

Model: Hydrox Control Unit (HCU) Remote

Flow rate: 1,27 l/min

Product no.: 812100


The HCU Remote contains an electrical hydraulic pump with frequency converter control. The pump is connected by hoses to the valve actuator. The control of the valve is based on the analog signal of the position transmitter. The hydraulic system is controlled with solenoid valves based on the valve position. The default closing time for each actuator size is calculated to give a slow closing to minimize the risk of water hammer in the pipe. The closing time and different operation ramps can be calibrated because of the frequency converter. For control of the hydraulic pump and the solenoid valves, programmable logic is used. The control system can be adapted to current circumstances and requirements.


The HCU Remote is provided with equipment to be controlled remotely. To transmit signals to and from the control center common transmission methods can be used.
