Monel Valves are made up of nickel alloys with other elements as alloyants. The majority of the composition is nickel, ranging from 52 to 67% and copper. Iron, manganese, carbon and silicon are some additions to Monel. Depending on the material composition, the grade of Monel differs. The monel ball valves are made for use with high concentration acids. Monel grades such as Monel 400, 450 and K500 can handle concentrated sulfuric acids. The material is a single phase alloy and does not transform with temperature. There are different types of valves made up of different types of Monel grades. The monel globe valves are used to regulate the fluids in larger diameter pipes. The smaller diameter pipes use gate, ball and butterfly valves for regulation.

There are also the check valve and control valve to check and control the flow in either one direction or two directions with relief and safety valves to maintain the pressure and protect the system. The monel gate valves use a gate of any type connected with a threaded stem to lower and raise the gate.
The gate sits in the seating when in the closed position and rises above the seating to open the valve. There are different dimensions and pressure ratings to the monel check valves and these depend on the standards. The check valve make sure that the flow is unidirectional. The Valve can vary in size from ½ inches to 24 inches and the pressure ratings vary with the valve size.
