Control valves and fail-safe action valves DN 15 to 150, PN 16 and 40, Kvs 0,4 to 360 m3/h |
Application
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.
Process media
The valves series RV/HU 2×1 are designed for regulation of the flow and pressure of liquids, gases and vapours such as water, steam, air and other media compatible with body material and with the valve inner parts. The application of valves made of spheroidal cast iron (RV/HU 211) for steam is limited by the following parametres: Steam must be superheated (its dryness x >= 0,98) and inlet pressure p1 <= 0,4 MPa when differential pressure is above-critical or p2 <=1,6 MPa when differential pressure is under-critical. In case these values are exceeded, it is necessary to use valve made of cast steel (RV/HU 221). To ensure reliable regulation, producer recommends to pipe a strainer in front of the valve or ensure in any other way that medium will not contain abrasive particles or impurities.
