The Hydraforce PD10-40-0-NS-170 (5261303) is a pilot-operated, spool-type, hydraulic directional valve designed for robust and efficient control in hydraulic systems. This screw-in, cartridge-style valve operates by allowing bidirectional flow from port 3 to port 2 in its neutral position while blocking port 4. Upon receiving a remote pilot signal at port 1, the spool shifts to connect port 3 to port 4, simultaneously blocking port 2. This functionality is crucial for applications requiring precise control of hydraulic flow direction and isolation of specific ports. The valve features a spring chamber vented to the atmosphere, which is internally O-ring sealed from the cartridge flow paths. This design ensures that the cartridge can be fully pressurized at any port without affecting the required pilot pressure, enhancing the valve's operational reliability and versatility in various hydraulic setups. The hardened spool and cage contribute to the valve’s durability and long service life. Rated for pressures up to 3500 psi (241 bar) and capable of handling fluid temperatures ranging from -40°C to +100°C (-40°F to +212°F) with standard Buna N seals, this valve accommodates a wide range of operating conditions. It also supports other seal materials for different temperature ranges, ensuring adaptability across various applications. The PD10-40-0-NS-170 is suitable for use with mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. Installation specifications include a VC104 cavity requirement with no orientation restrictions and a cartridge installation torque between 32.6 to 35.4 Nm (24 to 26 ft-lb). Optional accessories such as seal kits and housings are available to support custom configuration needs, making this valve a flexible choice for integrating into diverse hydraulic systems.
