Control valves DN 15 to 150, PN 16 and 40, Kvs 1,6 to 360 m3/h

Description
Control valves RV 2×5) are three-way valves with mixing or flow-diverting function. In regard of used actuators, the valves are suitable for regulation at lower differential pressures. Flow characteristics, Kvs values and leakage rates correspond to international standards. When assembled with a fail-safe action actuator, it closes straight way upon power failure.
Valves RV 2×5 are especially designed for Siemens actuators (Landis & Staefa), LDM, Johnson Controls, Honeywell and Belimo.

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
Valves series RV 2×5 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 inner parts. The application of valves made of spheroidal cast iron (RV 215) 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 225). 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.
