HDT’s Pressure Control Valve is used in U.S. Navy ship ColPro systems.

  • Functioning as a pressure control valve, it closes in response to drops or decays in zone pressure to limit air loss from the zone
  • Functioning as an overpressure valve, it opens to relieve air from the zone if pressure rises due to loss or failure of a mechanical exhaust system
  • The Pressure Control Valve is completely mechanical. It mounts at the zone boundary or to a duct that exhausts to atmospheric pressure.
  • The Pressure Control Valve has a nominal opening pressure of 2.0 in wg. An opening pressure of 1.5 in wg is also available.
