General
The direct operated 2-way pressure reducing valve type KRD is designed as tight seat valve. It is used for the leakage-free pressure reduction of a working pressure.
It basically comprises the screw-in housing (1) with spring (6) and adjustment type (5) as well as spool (3), valve seat (2) and closing element (4).
Function
In the initial position, the valve seat is open. Hydraulic fluid can flow from the main port ① to ②. If the pressure in the main port increases ② to the pressure value set at the adjustment type (5), the closing element (4) closes the connection ① to ②. The increasing system pressure (main port ①) no longer influences the pressure in main port ② (pressure holding function). Pressure losses in the main port ② (actuator) will be compensated by the valve.
