Pressure reducing valves of the DRV 3-series are diaphragm- or piston-operated, spring-loaded pressure reducing valves and have inlet pressure compensation. Fluctuating inlet pressures have no influence on the set outlet pressure. Pressure reducing valves protect plants from excessive supply pressure and are used in

industrial and commercial plants. The series is suitable for use with water and neutral, non-adhesive liquids, but can also be used for air and neutral gases when higher flow rates are required.
