Hcu Remote Introduction - Vexve Hydrox HCU Remote Installation, Operation And Maintenance Instructions

3. HCU Remote introduction

At operational changes, or emergencies, it is necessary to quickly close the valves. Therefore there is
a need to be able to remotely control valves from control centers. HCU Remote is meant for the most
demanding locations where remote control is required. All components are located in a rugged metal
enclosure and the electronics to electrical cabinet with high protection class.
HCU Remote is an electro-hydraulic control unit designed for remote and local operating of valves
equipped with hydraulic actuators. The control unit is equipped with a hand pump, so that actuators can
also be operated without electricity.
