The YeeValve TT7120/TT8120 Breather Valve is a Pressure Vacuum Relief Valve (Gravity Loaded, with Pipe) that excels in applications where steam must be vented to prevent air ingress and minimize steam escape, except during normal tank “breathing.” This critical function reduces product loss and protects the storage tank from potential damage. Excess vapors are expelled via a flanged outlet, enhancing fire safety and operational security.
