Control valves CV/SV 3×0 (Ex) and CV/SV 3×0 are single-seated valves designed for regulation and shut-off of process medium flow. In regard of a great variety of used actuators, the valves are suitable for regulation at low as well as high differential pressures in a diversity of operating conditions. Flow characteristics, Kvs values and leakage rates correspond to international standards.
Valves CV/SV 3×0 (Ex) are equipped with hand wheel or are especially designed for electromechanic actuators of the following producers: ZPA Nová Paka, Regada, ZPA Pečky, Schiebel, Auma, Rotork or for pneumatic actuators LDM, SPA Praha and Flowserve.
The valves series CV/SV 3×0 are designed for applications in heating, ventilation, power generation and chemical processing industries.
The valves CV/SV 3×0 Ex meet the requirements II 1/2G IIB TX acc.to ČSN-EN 13463-1 (6/2009) and ČSN EN 1127-1 (5/2008), and in connection with suitable actuators, they are also designed for applications in gas and chemical industries.
Valve body can be optionally made of cast steel or stainless steel.
The materials selected correspond to recommendations stipulated by ASME B16.34-2013 or ČSN-EN 12516-1 (1/2006).
Valves series CV/SV 3×0 are designed for regulation (CV 3×0) and shut-off (SV 3×0) of flow and pressure of liquids, gases and vapours without abrasive particles e.g. water, steam, air and other media compatible with material of the valve body and inner parts. The valves series CV /SV 3×0 Ex are also designed for control and shut-off of the flow and pressure of technical and fuel gases and inflammable liquids. To ensure a reliable regulation, the producer recomends to pipe a strainer in front of the valve into pipeline or ensure in any other way that process medium does not contain abrasive particles or impurities.
