The Hydraforce PD16-40-0-NS-170 (5262008) is a screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve designed for robust performance in various hydraulic systems. This valve operates such that in its neutral position, it allows bidirectional flow from port 3 to port 2 while blocking port 4. The spring chamber of the valve is vented to the atmosphere and is internally O-ring sealed from the cartridge flow paths. Upon receiving a remote pilot signal at port 1, the spool shifts to open ports 3 and 4 while blocking port 2. Constructed with hardened spool and cage for enhanced durability and longevity, this valve ensures reliable operation even under challenging conditions. Its optional sealed pilot and industry-common cavity design make it versatile for a wide range of applications. The PD16-40-0-NS-170 can be fully pressurized at any port without affecting the required pilot pressure due to its well-designed vented spring chamber. Key specifications include a pressure rating of up to 3500 psi (241 bar), an operating fluid temperature range of 40 to 120°C (40 to 248°F), and a maximum internal leakage of 245 ml/min at 3000 psi from port 1 to port 2 with a sealed spool. The unit weighs approximately 0.52 kg (1.15 lb) and is made from steel with work surfaces hardened and external surfaces zinc-plated for corrosion resistance. Installation specifications require a cavity type VC164 suitable for size-16/4-way cavities with a cartridge installation torque between 44.7 to 50.2 Nm (33 to 37 ft-lb). Accessories available include various seal kits such as Buna N, Viton, and Polyurethane options along with installation instructions for these seals. Housings are also available specifically designed for this model enhancing its adaptability across different setups.
