Switch Valve

RV/UV 2X0 series control valve is the process media regulation and role switch of high performance single seat valve.

Product Code: 2014516153321

Main features
1) Valve is compact in structure and light in weight;
2) The
switch valve has a variety of types of spool type ----V port, porous, guiding device of the pressure balance valve;
3) suitable for high temperature, high pressure difference and other harsh conditions;
4) The body is not susceptible to flash and cavitation damage;
5)good sealing performance, leakage of the highest level of VI
long service life;

Application

Switching Valves are designed for metallurgy, non-ferrous metals, petrochemical, electric power, papermaking and natural gas industry. RV/UV 2 switch valve also meet CSN-EN1127-1 9/1998 and CSN-EN 13463- 9/2002. Body material can choosed from ball type cast iron, cast steel and stainless steel. The material selection is in accordance with CSN-EN 1503-1 1/2002 (steel) and CSN-EN1503-3 (1/2002) (casting) standard. Various materials of the maximum working pressure and medium temperature 

Medium
RV/UV 2 switch valve of control valve can be adjusted (RV 2 x 0) and off (UV 2 x 0) of liquid, gas and steam, and some other body material compatible medium. RV/UV 2 x 0 (Ex) control valve series can also be used to control and shutdown flammable gas and liquid.

Installation
Switching Valve must be installed in the medium flow and arrow on valve body markers consistent. The valve can be installed in any position as long as actuator not under the body, when the medium temperature is higher than 150 DEG C should through the use of appropriate isolation pipe and valve or the body tilted to avoid the heat radiation and protects the actuator.

Differential pressure
△P value is to ensure the normal valve open / close under the function of the maximum differential pressure, to improve the valve service life is best not more than 1.6Mpa. Otherwise, according to the need to use with a hole or valve surfacing special hard alloy.
