Description	N/A 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 constant 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 DR08-01 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 1 exceeds 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.
Features	N/A Spring ranges up to 3000 psi (210 bar) Positive stop prevents spring from over adjustment (options V,H) Adjustable under full pressure Stroke limiting device for enhanced safety Fast response All external surfaces zinc-plated Hardened poppet to ensure minimal wear and extend service life Industry common cavity
