Steam pressure reducing valves are used to stabilize the steam pressure entering control valves, flow meters, or directly into the equipment. Choosing the appropriate type of steam pressure reducing valve is crucial.

For low flow equipment and facilities with low pressure control requirements, a direct-acting pressure reducing valve is recommended. For medium to low flow equipment, facilities, and piping systems, a pilot piston pressure reducing valve is available. For high flow, stable pressure control equipment, facilities, and piping systems, a pilot diaphragm pressure reducing valve can be selected.
