The Hydraforce 5614917.18 (5614917.18) is a screw-in, cartridge-style, direct-acting, spool-type hydraulic pressure reducing/relieving valve designed for secondary circuit pressure regulation. This model features an internal spring chamber drain and spool damping chamber, enhancing its reliability and performance in regulating hydraulic systems. In its default state, the PR50-38XXX allows bidirectional flow from port 2 to port 1 while maintaining constant drainage of the spring chamber through port 3. When a predetermined pressure level is reached at port 1, the cartridge 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. Notably, adjustments on this valve cannot be reversed out of the valve body, ensuring stability and preventing springs from becoming solid under high-pressure conditions. The valve offers optional spring ranges up to 227.5 bar (3300 psi), making it versatile for various applications. Its hardened spool and cage construction ensure long-lasting durability and dependable performance in demanding environments. This model also provides an option for protecting port 2 with a 60 mesh, 250-micron rated screen to prevent contamination in sensitive hydraulic circuits. With its industry-common size and robust design, this valve is suitable for integration into diverse hydraulic systems requiring precise pressure control and relief capabilities.
