Designed to balance pressure and vacuum conditions within a sealed vessel by releasing or admitting air and gas. If internal pressure reaches the pre-determined setting, valve will exhaust gas from the tank. If vacuum inside vessel becomes too great, the valve will admit air into the tank
Features
Available with local indication (QUALITROL 070)
Accurate and reliable pressure control
All bleeder models meet or exceed ANSI standards for transformers
Repeatability of bleeder is ±0.5 psig on both pressure and vacuum setting
Tough construction meant for indoor or outdoor use
Coated with a thermosetting powder coat finish to withstand rough environmental conditions
Screened openings inhibit entry of contaminates
Standard models available for top, side or bottom mounting
Indicator gauge can be added for simplified installation on vessel
