The Hydraforce PD12-41-0-N-170 (5263202) is a high-performance, screw-in, cartridge-style, pilot-operated, spool-type hydraulic directional valve designed for robust industrial applications. This valve functions by allowing bidirectional flow from port 3 to port 4 in its neutral position while blocking port 2. Upon receiving a remote pilot signal at port 1, the valve configuration shifts to open the flow from port 3 to port 2 and concurrently blocks the flow to port 4. It is important to note that pressure on port 4 influences the pilot pressure due to its direct connection with the spring chamber; this pressure must be considered along with the bias spring value for accurate operation. Constructed for durability and long service life, the PD12-41-0-N-170 features a hardened spool and cage. The valve is rated for pressures up to 3500 psi (241 bar) and can operate effectively within a fluid temperature range of -40°C to +100°C with Buna N seals, extending up to +204°C with Viton seals. Its design accommodates mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. The PD12-41-0-N-170 is versatile in installation options as well, compatible with VC124 cavities and does not have orientation restrictions during installation. It ensures minimal internal leakage (245 ml/min at 207 bar) and comes equipped with corrosion protection capable of handling up to 960 hours of salt spray per ASTM B117 standards. This valve’s compact design includes an internal wetted surface area of approximately 48.0 square inches and weighs about 0.91 lbs (0.41 kg), making it both efficient in function and economical in space utilization within hydraulic systems.
