|Control valves, fail-safe action valves and shut-off valves
DN 15 to 400, PN 16, 25 and 40, Kvs 0,01 to 1600 m3/h
These valves have a wide range of application in heating, ventilation, power generation and chemical processing industries. Valve body can be optionally made of spheroidal cast iron, cast steel and austenitic stainless steel according to operating conditions.
The valves series RV/HU/UV 2×0 are designed for control (RV/HU 2×0) and for shut-off (UV 2×0) of the flow of liquids, gases such as water, steam and other media compatible with material of the body and of the internal parts of the valve. The application of the valves made of spheroidal cast iron (RV/HU/UV 210) for steam is limited by the following parametres. The steam must be superheated (its dryness at the valve outlet x >= 0,98) and inlet pressure p1 <= 0,4 MPa when differential pressure is of above-critical value, and p2 <= 1,6 MPa when differential pressure is of under-critical value. In case these two conditions are not kept, it is necessary to use the value made of cast steel (RV/HU/UV 220). To ensure a reliable regulation, the producers recomends to pipe a strainer in front of the valve into pipiline or ensure in any other way that process medium does not contain abrasive particles or impurities.
