4-way, 2-position, pilot-to-shift, detented, directional valve

Capacity: 80 - 120 gpm320 - 480 L/min. | Cavity: T-64A
DCFD : 4-way, 2-position, pilot-to-shift, detented, directional valve
Technical Features [ + ]

Two-position, detented, 4-way directional cartridges are 6-port directional valves that can be configured with up to 3 different spool options. The supply port is port 3 and all ports will accept 5000 psi (350 bar). Capacity for these pilot-to-shift valves is dependent on the spool type specified.

  • All ports will accept 5000 psi (350 bar), including the x and y pilot ports (port 5 and port 6).
  • Leakage listed in technical data is for each path.
  • The pilot ports, 5 and 6, are positively sealed from the work ports.
  • Hardened spool and sleeve provide consistent and low spool leakage rates and excellent wear characteristics.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

Direct-acting valves are used to prevent over pressure, and pilot-operated valves are used to regulate pressure. If you are unsure, use a direct-acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot-operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.
