The 3-valve manifold is rugged, lightweight and compact, weighing less than 2.5 pounds and measuring 7.05"Wide x 6.25"High. Its all brass body, brass pipe fittings, copper tubing and plastic valves are ideal for high line pressures of 250 psi. The3-valve manifold eliminates the possibility of exceeding the pressure rating of the transducer. When combined with our Model 230 Wet-to-Wet Differential Pressure Transducer, the 3-valve manifold’s one-piece, machined brass body construction guarantees a leak-free system and minimizes external pipe connections.
