The Hydraforce 5617009.21 (5617009.21) is a spool type, pilot-operated hydraulic sequence valve with external pilot and internal spring chamber drain, identified by its model code PS10-43X. This valve is engineered to operate as a remote pilot-operated three-way valve, offering versatility in hydraulic systems. In its neutral or unpiloted state, the PS10-43X facilitates bidirectional flow between port 3 and port 2 while effectively blocking flow at port 4. The design incorporates a constantly drained spring chamber at port 4, ensuring consistent performance. When a predetermined pressure level is reached at port 1, the spool shifts position to close off flow from port 3 to port 2 and simultaneously opens the pathway from port 3 to port 4. This sequence valve features non-reversible adjustments that prevent the springs from reaching their solid state, enhancing operational reliability and safety. It offers optional spring ranges up to 151.7 bar (2200 psi) for varied application requirements. The hardened precision spool and cage construction contribute significantly to the valve's durability and long service life. Its industry-common size allows for seamless integration into existing systems without requiring extensive modifications. This hydraulic sequence valve is ideal for applications that demand precise control of fluid direction and pressure within complex hydraulic circuits, providing efficient management of hydraulic flow paths in various settings where dependable operation is critical.
