CVU-SWD Series

CVU-**-SWD, CVU-**-SWD3, CVU-**-ZSWD3, 1* Series Directional Valves with Electrical Indication

eaton CVCS-ZD(A)

These cartridge valves are integral assemblies of cover and insert with a main spool that is fully seated in its closed position. A coaxially mounted switch on the top cover provides a signal when the main spool is in position to close the mainstream flow.

On all models a spring holds the main spool in the closed position, requiring a small pressure to create flow through the valve. Pilot pressure from either a remote source (SWD models), or from a valve mounted directly onto the cover (SWD3 models) can be used to hold the spool fully closed. The “Dynamic” models, ZSWD3, with pilot operation of both opening and closing, cater for applications requiring fast response.

Flow can be in either direction (i.e. A to B, and B to A). The SWD(3) range is specifically designed for application in circuits and systems where electrical signalling of a known (closed) condition of the valve is required. The design of the main spool ensures that both switch indications, i.e. “valve closed” and “valve open”, occur when the valve is closed to mainstream flow.

Features and Benefits

  • Accurate and repeatable switching points.
  • Integrated and pre-set switch assembly, with pressuretight core tube, requires no setting adjustments to be made at installation.
  • Bidirectional flow capability, simplifies manifold block design.
  • Dynamic” version ensures positive opening and closing.
  • Dynamic” version offers fast response times.
  • Absence of spool seals improves reliability.
  • Robustly protected switch assembly.
  • Normally open and normally closed switch contacts.
  • Overload and polarity protected.
  • Conforms to ISO 7368

Flow Rates
