Series 300 line
Pressure balanced control valves
Control valves RV 3x2 (Ex) are single-seated valves with pressure-balanced plug designed for regulation of process medium flow. In regard of used actuators, the valves are suitable for regulation at high differential pressures with low-linear-force actuators. Flow characteristics, Kvs values and leakage rates correspond to international standards.
Valves RV 3x2 (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 or for pneumatic actuators LDM, SPA Praha and Flowserve.
The valves series RV 3x2 are designed for applications in heating, ventilation, power generation and chemical processing industries.
The valves RV 3x2 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.
Valves series RV 3x2 are designed for regulation 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 RV 3x2 Ex are also designed for control 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.
