Manual manifolds are designed to regulate compressed gases in high pressure cylinders (up to 3,000 psig) and are ideal for manifold applications not requiring automatic changeover from the service to the secondary bank. The MD Series duplex manifold is designed for manual changeover of 2 banks of cylinders. This system is often used as a high pressure reserve for bulk, portable bulk and gas generator systems.
