The Hydraforce PE42-S67K (5262139) is a high-performance hydraulic directional valve designed for advanced fluid control in hydraulic systems. This screw-in, cartridge-style valve features a proportional, spring-centered spool that is pilot operated, ensuring precise handling and responsiveness under various operating conditions. The valve’s operation allows for selective communication between ports; in its neutral position, inlet port 3 is blocked while ports 2, 4, and 5 are interconnected. Activation through a remote pilot signal at port 1 or port 6 causes the spool to shift proportionally to the pilot pressure applied, facilitating controlled flow direction either from port 3 to port 4 or in the reverse direction. Constructed with a hardened spool and cage, the PE42-S67K offers durability and a long service life. It boasts excellent metering characteristics with good linearity which enhances the efficiency of hydraulic operations. The non-symmetrical design of the spool provides meter-in control only, tailored specifically for applications requiring precise flow regulation. This valve is versatile with its compatibility with ISO cavities and can handle high-pressure ratings up to 345 bar (5000 psi) at port 3 and slightly lower pressures at other ports. The maximum internal leakage is minimal at just 737 ml/min at a pressure of 207 bar (3000 psi), underscoring its efficiency in maintaining system integrity. Additional features include options for different seal materials such as Buna N, Viton, and Polyurethane to suit various operational demands and environmental conditions. The unit’s compact design also contributes to ease of installation in space-constrained applications.
