The Hydraforce PD16-44-0-N-170 (5262521) is a pilot-operated, spool-type hydraulic directional valve designed for robust hydraulic system applications. This screw-in, cartridge-style valve is engineered to control flow directions in a hydraulic circuit effectively. In its neutral position, the PD16-44-0-N-170 blocks flow from port 2 to port 3. Upon receiving a remote pilot signal at port 1, the spool shifts to allow bidirectional flow between these ports. An important feature of this model is the vented spring chamber at port 4, which is internally O-ring sealed to prevent leakage from the cartridge flow paths. The pressure at port 4 influences the pilot pressure required for operation and must be considered alongside the bias spring value. Constructed for durability, the valve features a hardened spool and cage, ensuring extended operational life even under demanding conditions. It offers compatibility with industry-standard cavity VC12S6 and operates efficiently within a pressure range up to 241 bar (3500 psi) and temperature range from -40°C to +120°C (-40°F to +248°F). The maximum internal leakage is specified at 245 ml/min at 207 bar (3000 psi), highlighting its precision in fluid control. The unit’s external surfaces are zinc-plated for corrosion resistance, while its internal work surfaces are hardened steel. Weighing approximately 0.52 kg (1.15 lb), it ensures easy installation with a recommended cartridge installation torque between 62.4 to 73.2 Nm (46 to 54 ft-lb). Optional accessories include various seal kits such as Buna N, Viton, and Polyurethane options, each accompanied by installation instructions to facilitate proper setup in diverse hydraulic systems using available Hydraforce housings specific for this valve type.
