Zawory szeregu 900 line
The valves with extended outlet of series RV 902 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 to eliminate the valve´s high differential pressures with a high resistance to wearing caused by flow and effects of expanding steam. It also ensures a low noisiness level. The valve is equipped with packing type “Live Loading”.
The valves are supplied in angle execution with weld ends connection and are actuated with both electric and pneumatic actuators. The connection is designed for using actuators of the following producers: ZPA Pečky, Regada Prešov, Auma, Schiebel and Flowserve. It is also possible to use fast acting electrohydraulic actuators for quick closing or opening.
The valves of series RV 902 are especially designed for industry applications such as heating plants, power plants or regulation of technological processes.
The valves are especially designed for the flow and pressure control of the process medium without impurities, however they can be used for gases and vapours when inlet and outlet flow velocities are kept within the permissible range. The common process media are for example water, steam and other 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.
