Description
High capacity manifolds intended for use with Shank 901 and 903 relief valves. All steel and stainless steel construction with Teflon O-rings on the stem. Due to Teflon sealing surfaces, these manifolds are rated for 500°F and 500# pressure. Construction is the same as the 900MW manifold except the 2” Schedule 160 pipe is replaced by a 2” FNPT half coupling. Cv rating for both ports is 47.5 (for the 901M), and 66 (for the 903M). Manifold weight is 30 lbs.
903M Port Sizes: 2” x 1 1/2” x 1 1/2” FNPT
903M manifolds can be used with the following relief valves
