Shut-off and control valves RV/UV 2x0 (Ex) are single-seat globe valves designed to control and shut off the medium flow. Due to the wide range of actuators used, they are suitable for regulation at both low and high pressure drops under the most diverse operating conditions. Flow characteristics, Kvs coefficients and leakage correspond to international standards. They are adapted for the connection of electrohydraulic drives with a safety function (in the event of a power failure, the valve closes the medium flow). These valves are intended for use in heating and air conditioning technology, energy and chemical industry. Depending on the operating conditions, it is possible to use valves made of ductile iron, cast steel and austenitic stainless steel. Valves RV/UV 2x0 Ex meet the requirements of II 1G IIB according to ČSN-EN 50014 and in connection with suitable drives are intended for use in the gas industry and chemical industry.
Control valves 200 line are designed for regulation and shut-off of process liquid flow. In Ex proof version meet the requirements II 1/2G IIC T6...T1 Ga/Gb according to ČSN EN ISO 80079-36 (9/2016) and ČSN EN 1127-1 ed.2 (1/2012). The selected materials correspond to recommendations stipulated by ČSN EN 12516-1 (8/2015) - steel and ČSN EN 1503-3 (1/2002) - cast. The maximal permissible operating pressures in behaviour with types of material and temperature are specified in attached catalogue.
