The Hydraforce 5606438.02.75 (5606438.02.75) is a screw-in, cartridge-style hydraulic pressure reducing/relieving valve that features a direct-acting, spool-type design with an internal spring chamber drain and spool damping chamber. This valve is engineered to function as a pressure-regulating device for secondary circuits in hydraulic systems. In its normal state, it allows bidirectional flow from port 2 to port 1 while maintaining constant drainage of the spring chamber at port 3. When the pressure at port 1 reaches a predetermined level, the cartridge shifts to block flow at port 2, effectively regulating the pressure at port 1 and relieving excess pressure from port 1 to port 3 if necessary. The valve includes optional features such as spring ranges up to 248 bar (4200 psi) and a protective 233-micron screen for port 2. It also boasts hardened spool and cage components for enhanced durability and longevity within a compact size that aligns with industry standards. Additionally, adjustments are designed to prevent backing out of the valve and ensure that springs do not become solid during operation.
