Two-stage valves are a type of pressure control valve. They are used in hydraulic systems that are supplied by dual stage pumps, a combination of high-pressure pump and low-pressure pump.
The two-stage valve type NE combines the two pump delivery flows into a common volumetric flow. It switches the low-pressure pump to unpressurised circulation if the pressure value set is reached. It protects both pumps against exceeding the high or low-pressure value set.
The two-stage valve type NE is used with directional valves to control double-acting hydraulic cylinders.
Features and benefits:
Operating pressures up to 700 bar
Direct mounting on hydraulic power packs
Direct combination with valve banks
