Quad Manifold with (4) A1311A Relief Valves, 250 PSI Relief Valve Pressure Rating, 12,481 (2) Flow Rating SCFM/Air at 120% of Set Pressure

For use with large NH3 stationary storage tanks with 2" FNPT openings. These manifolds include an additional relief valve (excluded from the flow rating) which allows for service and/or exchange of any one relief valve without evacuating the tank. The large port selection handle allows for each specific valve port to be closed off so that the relief valve may be removed while the remaining valves stay in service and pressurized, protecting the tank. Each manifold model is rated based on the flow through the relief valve with one valve removed from service.
