Design Pressure Retaining Valve Type 586

Function
The desired pressure in the valve inlet pipe is set by the adjustable spring force. If the inlet pressure rises above the set value, e.g.
due to an over capacity of the pump, the valve piston is lifted against the spring force. Consequently, the valve opens, and there is a
reduction of pressure into the outlet. If the pressure decreases in the valve inlet pipe, the spring resistance pushes the piston down
in the direction of the valve seat and closes, as soon as the inlet pressure sinks below the preset spring tension. In this way, a cons-
tant pressure in the supply line is ensured.
