The Hydraforce 5606454.19.5 (5606454.19.5) is a screw-in, cartridge-style hydraulic pressure reducing/relieving valve, specifically designed for direct acting and spool type applications. This valve features an internal spring chamber drain and a spool damping chamber, making it an effective pressure regulating device for secondary circuits. In its normal state, the pr58-38xxx model allows bidirectional flow from port 2 to port 1 while maintaining a constant drain at port 3 from the spring chamber. When the predetermined pressure is reached at port 1, the valve shifts to block flow at port 2, thus regulating the pressure at port 1 and allowing relief from port 1 to port 3. The design includes options such as a protective screen for port 2 and various spring ranges up to 248 bar (4200 psi), ensuring versatility in application. The construction includes hardened spool and cage components, enhancing durability and service life within its compact size that aligns with industry standards. Adjustments are designed to prevent backing out or causing springs to go solid, ensuring reliable performance throughout its operational lifespan.
