3-way, 2-position, vent-to-shift diverter valve, normally open

Capacity: 60 gpm240 L/min. | Cavity: T-33A
DSGY : 3-way, 2-position, vent-to-shift diverter valve, normally open
Technical Features [ + ]

This vent-to-shift diverter valve is a 2-position, 3-way cartridge that is normally open from port 3 to port 4. When port 1 is vented, the pressure differential between port 3 and port 1 exceeds the spring force causing the valve to shift, thereby connecting port 3 to port 2.

  • This valve is not bistable; it is capable of modulating between the two positions shown.
  • Vent flow out of port 1 is pressure compensated and is listed in Technical Data.
  • There must be a pressure source at port 3, relative to port 1, to shift the valve.
  • One application of this valve is to be used in pairs to select between 2 motors or pumps.
  • One pilot valve may be used to vent multiple diverter valves if blocking checks are used at port 1 of each diverter. If blocking checks are not used there will be interaction between high and low pressure legs of the circuit.
  • The vent-to-shift function is self cleaning and therefore insensitive to contamination.
  • 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.
