The Hydraforce 5614901.M70 (5614901.M70) is a screw-in, cartridge-style, direct-acting spool type hydraulic pressure reducing/relieving valve. This model features an internal spring chamber drain and a spool damping chamber, making it highly effective for pressure regulation in secondary circuits. During operation, the PR50-38XXX allows bidirectional flow from port 2 to port 1 while maintaining a constant drain at port 3. When the pressure at port 1 reaches a predetermined level, the valve shifts to block flow at port 2, thus regulating 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 design ensures that adjustments cannot be backed out of the valve and prohibits springs from going solid, enhancing reliability and durability. The valve offers optional spring ranges up to 227.5 bar (3300 psi) and features hardened spool and cage components for extended lifespan. Optional protection for Port 2 with a 60 mesh, 250-micron rated screen is also available with option S. Its industry-common size ensures compatibility in various applications requiring precise hydraulic pressure control and regulation.
