The Hydraforce 5614900.03.9 (5614900.03.9) 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 effective pressure regulating device for secondary circuits. The valve allows bidirectional flow from port 2 to port 1 in its steady state while maintaining constant drainage at port 3. Once a predetermined pressure is reached at port 1, the cartridge shifts to block flow at port 2, thereby regulating the pressure at port 1. Additionally, the valve can relieve port 1 to port 3 at a variable value over the set reducing pressure. Notably, adjustments on this valve cannot be backed out and are designed to prevent springs from going solid. It offers optional spring ranges up to 227.5 bar (3300 psi) and features a hardened spool and cage for extended longevity. The PR50-38XXX model is compatible with industry-common sizes and provides an option to protect Port 2 with a 60 mesh, 250-micron rated screen (option S). This robust construction ensures reliable performance in various hydraulic applications requiring precise pressure control and regulation.
