Pressure Control Modules – PCM 06-06

The Polyhydron PCM 06-06 is a pressure control module designed specifically for Hi-Low hydraulic systems. It functions by controlling double pumps—unloading the low-pressure (high-flow) pump to the tank when a set pressure is reached, while the high-pressure (low-flow) pump remains active to maintain system pressure.

About this item

The Polyhydron Pressure Control Modules – PCM 06-06 is designed to control double pumps in a Hi-Low hydraulic system. It automatically unloads the low-pressure pump when system pressure exceeds the preset value on the unloader valve. At the same time, it relieves the high-pressure pump when the system reaches the set pressure, ensuring efficient operation and protection of the hydraulic system.
