The Hydraforce 5606457.M140 (5606457.M140) is a screw-in, cartridge-style, direct-acting spool-type hydraulic pressure reducing/relieving valve. This component features an internal spring chamber drain and spool damping chamber, making it an efficient pressure regulating device for secondary circuits. In its steady state, the pr58-38xxx model allows bidirectional flow from port 2 to port 1, with a constant drain at port 3. When the predetermined pressure at port 1 is reached, the cartridge shifts to block flow at port 2, effectively regulating pressure at port 1. The valve also has the capability to relieve pressure from port 1 to port 3 under this mode of operation. For added protection, port 2 can be equipped with a 60 x 60 mesh screen. The design includes features that prevent adjustments from being backed out and ensure springs do not go solid during operation. Optional spring ranges are available up to 248 bar (4200 psi), along with an optional 233-micron screen for enhanced filtration. The hardened spool and cage contribute to the valve's long life, while its compact size aligns with industry-common dimensions for easy integration into existing systems.
