The Hydraforce 5606451.08 (5606451.08) is a screw-in, cartridge-style, direct-acting, spool-type hydraulic pressure reducing/relieving valve. This model features an internal spring chamber drain and a spool damping chamber, making it ideal for precise pressure regulation in secondary circuits. In its steady state, the PR58-38XXX valve allows bidirectional flow from port 2 to port 1 while maintaining constant drainage of the spring chamber at port 3. When a predetermined pressure is reached at port 1, the cartridge shifts to block flow at port 2, effectively regulating the pressure at port 1 and relieving excess pressure from port 1 to port 3. The design includes a feature where adjustments cannot be backed out of the valve, ensuring reliability and preventing springs from going solid. Optional components include various spring ranges up to 248 bar (4200 psi) and a protective screen for port 2 with a mesh size of 60 x 60 or an optional screen with a finer filtration level of 233 microns. The valve's hardened spool and cage ensure long life and durability while maintaining compatibility with industry-common sizes for ease of integration into existing systems.
