The Hydraforce 5614902.21 (5614902.21) is a screw-in, cartridge-style, direct-acting, spool-type hydraulic pressure reducing/relieving valve equipped with an internal spring chamber drain and spool damping chamber. This component is specifically engineered to function as a pressure regulating device for secondary circuits in hydraulic systems. In its standard operating state, the pr50-38xxx model allows fluid to flow bidirectionally from port 2 to port 1 while maintaining a constant drain at port 3 through the spring chamber. When the pressure at port 1 reaches a predetermined level, the valve 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 at variable values over the set reducing pressure. The design features adjustments that cannot be backed out of the valve and includes safeguards against springs going solid during operation. It offers optional spring ranges up to 227.5 bar (3300 psi) and is constructed with hardened spool and cage components for extended durability. The valve also conforms to industry-common sizes, ensuring compatibility with various hydraulic applications. An optional feature includes protecting port 2 with a 60 mesh, 250-micron rated screen for enhanced operational reliability in demanding environments.
