The Hydraforce 5614911.M33 (5614911.M33) is a screw-in, cartridge-style, direct-acting, spool-type hydraulic pressure reducing/relieving valve. This valve features an internal spring chamber drain and a spool damping chamber, making it an ideal choice for pressure regulation in secondary circuits. It allows bidirectional flow between port 2 and port 1 in its steady state, with the spring chamber consistently drained at port 3. When a predetermined pressure is reached at port 1, the valve shifts to block flow at port 2, effectively 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 design includes optional protection for port 2 with a 60 mesh, 250-micron rated screen. Key features include non-backable adjustments that prevent springs from going solid and optional spring ranges up to 227.5 bar (3300 psi). The valve's hardened spool and cage ensure long-lasting durability while maintaining compatibility with industry-common sizes.
