The Hydraforce 5614902P.M120 (5614902P.M120) is a screw-in, cartridge-style, direct-acting spool type hydraulic pressure reducing/relieving valve. It features an internal spring chamber drain and a spool damping chamber, making it an efficient pressure regulating device for secondary circuits. The valve operates by allowing bidirectional flow from port 2 to port 1 while maintaining a constant drain at port 3 in its steady state. When a predetermined pressure is reached at port 1, the cartridge shifts to block flow at port 2, effectively regulating the pressure at port 1. Additionally, the valve can relieve pressure from port 1 to port 3 over a variable value above the set reducing pressure. Notably, adjustments on this valve cannot be backed out, preventing springs from going solid and ensuring stability during operation. It offers optional spring ranges up to 227.5 bar (3300 psi) and features hardened spools and cages for extended durability. The design includes an option for protecting port 2 with a 60 mesh, 250-micron rated screen. This industry-common size valve is engineered for longevity and reliability in various hydraulic applications requiring precise pressure control and relief functions.
