DFT Durabla Vacuum Breakers provide effective protection
against collapse of pressure vessels, tanks and rolls.
They Prefent condensate "back-up" when equipment is
shut down or inlet steam is reduced by modulating
control valves. In piping systems, DFT Durabla 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
Cracking pressure for vertical flow will be slightly different: upward flow, slightly higher; downward flow, slightly less.
*(1) - Light spring available: Cracking Pressure = .18 PSI (5.0 inches of water)
*(2) 0.24 PSI Crack Pressure Spring (+/- 10%)
