The Hydraforce 5606454.M69 (5606454.M69) is a screw-in, cartridge-style hydraulic pressure reducing/relieving valve. This direct-acting, spool-type valve features an internal spring chamber drain and a spool damping chamber, making it ideal for pressure regulation in secondary circuits. In its normal state, the PR58-38XXX model allows bidirectional flow from port 2 to port 1 while maintaining constant drainage of the spring chamber at port 3. When the predetermined pressure at port 1 is reached, the valve shifts to block flow at port 2, effectively regulating the pressure at port 1. Additionally, it can relieve excess pressure from port 1 to port 3. The design includes a feature where adjustments cannot be backed out of the valve, preventing springs from reaching a solid state. Optional configurations include 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 of 233 microns for enhanced filtration. The hardened spool and cage contribute to long-lasting performance in various applications. This compact valve fits industry-common sizes and offers reliable operation in hydraulic systems requiring precise pressure control and relief functions.
