The Hydraforce 5614901.18.5 (5614901.18.5) is a screw-in, cartridge-style, direct-acting spool type hydraulic pressure reducing/relieving valve designed for efficient pressure regulation in secondary circuits. This valve features an internal spring chamber drain and a spool damping chamber, enhancing its operational reliability and performance. In its steady state, the PR50-38XXX model allows bidirectional flow between port 2 and port 1 while maintaining constant drainage at port 3. When the pressure at port 1 reaches a predetermined level, the valve shifts to block flow at port 2, effectively regulating the pressure at port 1. Additionally, it can relieve excess pressure from port 1 to port 3 over a variable value above the set reducing pressure. The valve includes several key features such as non-backout adjustments that prevent springs from going solid and optional spring ranges up to 227.5 bar (3300 psi). The components are constructed with hardened spools and cages for enhanced durability and long life, making it suitable for demanding applications where longevity is critical. The design accommodates an industry-common size, ensuring compatibility with various systems. An optional feature includes a protective screen rated at 60 mesh or 250 microns for Port 2, providing additional safeguarding against contaminants in specific applications where this option is utilized.
