The Hydraforce 5614931.18.5 (Material Number: 5614931.18.5) is a screw-in, cartridge-style, direct-acting spool type hydraulic pressure reducing/relieving valve designed for secondary circuit pressure regulation. This valve features an internal spring chamber drain and a spool damping chamber to enhance performance and reliability. In its steady state, the PR50-38XXX model allows bidirectional flow from port 2 to port 1 while keeping the spring chamber constantly drained at port 3. When a predetermined pressure is reached at port 1, the cartridge shifts to block flow at port 2, thus regulating 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 consistent operation within optional spring ranges up to 227.5 bar (3300 psi). The valve's hardened spool and cage contribute to its long lifespan and durability, making it suitable for various hydraulic applications requiring precise pressure control in secondary circuits. The option of protecting Port 2 with a 60 mesh, 250-micron rated screen adds an extra layer of versatility and reliability in demanding environments. The industry-common size ensures compatibility with existing systems or ease of integration into new designs.
