Vacuum Breaker Threaded Check Valve


DFT Vacuum Breaker Valve
  • DFT┬« Vacuum Breakers provide effective protection against collapse of pressure vessels, tanks and rolls.
  • Vacuum Breakers prevent condensate back-up when equipment is shut down or inlet steam is reduced by modulating control valves.
  • Vacuum Breakers are used to break siphons, prevent pipe collapse during transient pressure drops, and to provide addition of air on the downstream side of check valves to dampen water hammer.
