The Hydraforce 5614916.12 (5614916.12) 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 a spool damping chamber to enhance its performance. In its normal operation, the pr50-38xxx model allows bidirectional flow from port 2 to port 1 while maintaining constant drainage at port 3. When a predetermined pressure is reached at port 1, the valve shifts to block flow at port 2, thereby regulating the pressure at port 1. Additionally, it can relieve pressure from port 1 to port 3 over a variable value above the set reducing pressure. The valve includes options for protecting port 2 with a 60 mesh, 250-micron rated screen and offers optional spring ranges up to 227.5 bar (3300 psi). It is built with hardened spool and cage components for enhanced durability and long life in demanding applications. The design ensures adjustments cannot be backed out of the valve and prevents springs from going solid, ensuring reliable operation throughout its lifespan.
