The Three Valve Manifold is designed to simplify remote mounting of differential pressure instruments. It typically includes two block (isolation) valves and one equalizer valve, providing safe, leak-free performance. Standard dimensions are based on the common 54 mm (2 1/8 inch) instrument connection, but versions are available for other center distances (55 mm, 56 mm, and 57 mm) to suit different instruments. This manifold is widely used in field installations, eliminating the need for conventional piping arrangements.
