A screw-in cartridge, direct acting, spool type, pressure reducing/relieving valve with internal spring chamber drain, intended for use as a pressure regulating device. This valve maintains a secondary regulated/reduced pressure regardless of pressure variations in the primary system. In addition to the reducing function, this valve also provides a relief function from the reduced pressure port to the tank port, if pressure in the secondary circuit exceeds the set pressure.

Operation

N/A The DR10-01 allows bidirectional flow between port 2 and port 1 with the spring chamber drained through port 3. Once the pressure setting is reached at port 1, the spool shifts to restrict the flow at port 2, thereby regulating pressure at port 1. If pressure at port 1exceeds the setting of the valve, the spool will shift further and relieve excess pressure through port 3. Any pressure at port 3 is directly additive to valve pressure setting.
