The Hydraforce PD16-S51-0-N-70 (5262561) is a high-performance, screw-in, cartridge-style, pilot-operated, spool-type hydraulic directional valve designed for robust industrial applications. This valve operates by allowing flow between ports 2, 3, and 4 in its neutral position. Upon receiving a remote pilot signal at port 1, the spool shifts to block all ports to control the flow direction effectively. One of the key features of this model is its vented spring chamber which vents to the tank through port 5. This design ensures that the valve can be fully pressurized at ports 1, 2, 3, and 4 without impacting the required pilot pressure, although pressure at port 5 will influence this required pressure. Constructed with durability in mind, the PD16-S51-0-N-70 boasts a hardened spool and cage ensuring a long service life even under demanding conditions. The external surfaces are zinc-plated and it utilizes Buna N O-rings as standard sealing materials which provide excellent resistance against various fluids and temperatures ranging from -40 to +120°C (-40 to +248°F). Its pressure rating stands impressively at up to 241 bar (3500 psi), with maximum internal leakage specifications of 410 ml/min between ports 3 and 2 at 207 bar (3000 psi), and up to 820 ml/min between ports 3 and 4. This valve offers flexibility in installation with a cavity specification of VC16S5 for size-5-way cavities and requires an installation torque ranging from 62.4 to 73.2 Nm (46 to 54 ft-lb). Optional accessories like seal kits with installation instructions and various housings including a compatible housing for a '165w valve body' are available to enhance functionality and ease of use in various hydraulic systems configurations.
