The Hydraforce 5606451.18 (5606451.18) is a screw-in, cartridge-style, direct-acting spool-type hydraulic pressure reducing/relieving valve designed for secondary circuit pressure regulation. This model features an internal spring chamber drain and a spool damping chamber, providing efficient pressure control by allowing bidirectional flow from port 2 to port 1 in its steady state while maintaining a constant drain at port 3. When the predetermined pressure is reached at port 1, the valve shifts to block flow at port 2, effectively regulating the pressure at port 1 and relieving excess pressure from port 1 to port 3. For added protection, port 2 can be equipped with an optional 60 x 60 mesh screen. The valve's design includes adjustments that cannot be backed out and prevents springs from becoming solid, which enhances operational reliability. Optional spring ranges are available up to 248 bar (4200 psi), catering to various application needs. Additionally, a hardened spool and cage ensure durability and long service life, while its compact size aligns with industry standards for easy integration into existing systems.
