Relief Valve Manifold

NH3 (anhydrous ammonia) safety relief valve manifolds, Catalog No. A-462, provides two 1-1/4 FPT openings for installation of safety relief valves. Stainless steel bleeder valves are provided below each of the two openings to evacuate the chamber before removing the relief valves for periodic inspection and maintenance. The shutoff assembly is designed so that only one port may be closed at one time thereby assuring the protection of one relief valve at all times.
