Trane TUB8058 Tube 320788-703 Its high-flow design minimizes pressure

Its high-flow design minimizes pressure drop while providing the fast-acting response time required for modern combustion system components

While some 200RB valves can be converted for bi-flow use with a kit

resulting in enhanced energy efficiency and reduced mechanical wear

or failure to close the pressure switch

this specific model is factory set and certified for ASME Section I steam service
