The YeeValveTT7130/TT8130 Breather Valve is a Pressure Relief Valve (Weight Loaded, with Pipe) uniquely engineered with a different-sized inlet/outlet flange compared to similar models. It features a smaller downstream pipe flange, designed to reduce installation costs. The Y2200A model is specifically developed for applications requiring only a pressure relief system. Escaping steam is channeled through a piped connection to the outlet flange, enhancing fire safety and operational security.
