Breather Valve cum Flame Arrester
Model No: KCPL-FA-BRVL
Breather Valve cum Flame Arrester is a combined tank-protection device designed to provide controlled pressure / vacuum breathing while also preventing flame propagation through the vent line.
The breather section uses pressure and vacuum pallets with weight-loaded or spring-loaded operation to protect the tank from excessive internal pressure or vacuum. The integrated flame-arrester section uses a crimped ribbon or bird-mesh element to help stop flame from travelling toward the protected tank.
Available in carbon steel, stainless steel and PTFE-coated body options, with multiple sizes and connection types, the unit is suitable for flammable-liquid, fuel, solvent and chemical storage applications requiring both tank breathing and flame protection.
