DN 15 to 150, PN 16 to 160, Kvs 0,1 up to 250 m3/h
The valves series RV 501 are single-seated control valves of a unit construction designed to fit in all demands of an appliance the valve is designed for. The pressure-balanced, multi-step throttling system is always designed with regard to the resistance to creation and effects of cavitation and noisiness. The valves can be delivered with weld ends or flanges having faces acc. to the customer´s requirements and demands.
The valves are actuated with linear actuators. The connection is designed for using both domestic and foreign actuators of the following producers: ZPA Pečky, Regada, Auma, Schiebel and Foxboro.
The sphere of application of these valves continues in the sphere of application for the valves series RV 210 to RV 235. They are especially designed for industry applications such as heating plants, power plants or regulation of technology processes. The max. permissible operating pressure values correspond to EN 12 516-1.
The valves are especially designed for the flow and pressure control of liquid process media without impurities. The common process media are for example water and other liquid media with no special demands on the used type of material of the valve. The producer recommends to pipe a strainer into pipeline in front of the valve when impurities are present. Impurities can affect the quality and reliability of regulation and can cause a reduction of the valve service life.The valve application for any other media should be consulted with the producer because of the type of material that is in contact with the process medium.
