The YeeValve TT7123/TT8123 Breather Valve is a Pressure Vacuum Relief Valve (Spring Loaded, with Pipe) designed to efficiently manage the release of pressure and vacuum in containers where steam must be expelled. It incorporates a special pallet within the TT7123/TT8123 casing that nearly eliminates air ingress and steam escape, except during the normal “breathing” of the storage tank. This functionality significantly reduces product loss and shields the tank from potential damage. Vapors that do escape are discharged through a flanged outlet, contributing to enhanced fire safety and operational security.
