The Hydraforce 5614900.M28.5 (5614900.M28.5) 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 ideal for use as a pressure regulating device in secondary circuits. It allows bidirectional flow from port 2 to port 1 while maintaining constant drainage at port 3 under steady-state conditions. When the predetermined pressure 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 pressure from port 1 to port 3 over a variable value above the set reducing pressure. The valve's design ensures that adjustments cannot be backed out and prevents springs from going solid, offering optional spring ranges up to 227.5 bar (3300 psi). Its construction includes a hardened spool and cage for enhanced durability and long life, fitting into industry-common sizes for versatile application across various systems.
