3-Valve Manifold

A 3-valve manifold is a compact industrial assembly designed to safely control, isolate, and service pressure instruments. Depending on the system setup, it features either two isolation valves and one equalizing valve to balance pressures and calibrate differential pressure transmitters, or two isolation valves and one bleed/vent valve to safely release trapped media before removing pressure gauges.
