  • EHC (Solenoid) Valves | LunchBox Sessions

    Pressure Reducing Valves. The EHC valve is a pressure reducing valve, and when no electrical current passes through the solenoid, no pressure is made available on the valve outlet. When the current is increased, the outlet pressure will rise. In a non-electric valve, the pressure setting changes would be made by tensioning a spring using an

  • What is a Pressure-Reducing Valve and How is it Used in

    A pressure-reducing valve is normally an open, 2-way valve that allows system pressure fluid to flow through it until a set pressure is reached downstream. It then shifts to throttle flow into the branch. The forces exerted by pressure downstream actuates a pressure-reducing valve. A pressure drop across the valve's spring-based main spool is

    Last, set the pump pressure compensator setting to the actual system pressure that is required. Remember, the system pressure relief valve must be set about 200 PSI above the pump pressure compensator setting, or the two pressure settings will fight each other. This would result in the system acting as if it were a fixed displacement system.
