The Hydraforce 5606456.M75 (5606456.M75) is a screw-in, cartridge-style hydraulic pressure reducing/relieving valve, designed for direct acting and spool-type operations. This compact valve features an internal spring chamber drain and a spool damping chamber, making it ideal for regulating pressure in secondary circuits. In its steady state, the PR58-38XXX model allows bidirectional flow between port 2 and port 1 while maintaining a constant drain at port 3. When the predetermined pressure is reached at port 1, the cartridge shifts to block flow at port 2, effectively regulating pressure at port 1 and relieving it to port 3 as needed. The valve's design includes adjustments that cannot be backed out, ensuring springs do not become solid during operation. It offers optional spring ranges up to 248 bar (4200 psi) and an optional 233-micron screen for enhanced performance. The valve's hardened spool and cage contribute to its long operational life, while its industry-common size ensures compatibility with various systems. Port 2 can be optionally protected by a 60 x 60 mesh screen for added durability and reliability in demanding applications.
