The Hydraforce PE16-S67K (5262151) is a high-performance, screw-in, cartridge-style hydraulic directional valve designed for advanced fluid control applications. This proportional, pilot-operated valve features a spring-centered spool that provides precise control over hydraulic flow directions based on the pilot pressure signals received at its ports. In its neutral position, the valve blocks the inlet port 3 while allowing communication between ports 2, 4, and 5. Activation of a remote pilot signal at port 1 or port 6 shifts the spool proportionally to allow or reverse the flow between these ports, facilitating efficient operation of hydraulic cylinders or motors. The PE16-S67K is engineered with a non-symmetrical spool that offers metering control and is constructed with hardened steel for the spool and cage to ensure durability and a long operational life. Its external surfaces are zinc-plated for corrosion resistance, while standard buna-N o-rings provide reliable sealing. The valve operates effectively within pressure ratings of up to 345 bar (5000 psi) at port 3 and up to 241 bar (3500 psi) at ports 2 and 4, with a lower rating of 28 bar (400 psi) at pilot ports 1 and 6. This model's design includes an optimal cavity specification of VC16S6 for installation in corresponding sized cavities. It also allows for various seal kit options including Buna N, Viton, and Polyurethane to suit different application needs. The PE16-S67K weighs approximately 0.76 kg (1.68 lb) and requires an installation torque between 62.4 to 73.2 Nm (46 to 54 ft-lb), ensuring secure and stable integration into hydraulic systems.
