The Hydraforce 5606450.M21 (5606450.M21) is a screw-in, cartridge-style, direct-acting, spool-type hydraulic pressure reducing/relieving valve. This product features an internal spring chamber drain and a spool damping chamber, making it an efficient pressure regulating device for secondary circuits. In its default state, the pr58-38xxx model allows bidirectional flow from port 2 to port 1 while maintaining a constant drain at port 3. When the predetermined pressure is reached at port 1, the valve shifts to block flow at port 2 and regulates pressure at port 1. Additionally, in this mode, it can relieve pressure from port 1 to port 3. Port 2 may be equipped with a protective 60 x 60 mesh screen for added safety. The design includes adjustments that cannot be backed out of the valve and ensures that 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 hardened spool and cage contribute to its long lifespan, and its compact size fits industry-standard dimensions.
