Breather Valve
Model No: KCPL-FA-BRV
Breather Valves are designed to protect storage tanks and low-pressure vessels from excessive internal pressure or vacuum during filling, emptying and thermal expansion or contraction.
The valve operates through pressure and vacuum pallets that open automatically when the preset tank pressure or vacuum limit is reached. The required setting can be achieved using a counterweight / weight-loaded arrangement or spring-loaded mechanism, depending on the application.
Available with carbon steel, stainless steel and PTFE-coated body options, along with flanged, threaded or Tri-Clover connections, the breather valve can be configured for different tank and process requirements. For applications handling flammable vapours, a Breather Valve cum Flame Arrester configuration is available with a separate flame-arresting section.
