Description

Control Valves

RV 502 series control valves is a high performance single seat control valve with external expansion output port, which is designed to meet various needs.


Product Code: 201451615320


Main features

1) Compact structure and light weight.
2) The pressure balance valve with multistage throttling
3) Suitable for high temperature, high pressure, high pressure difference, etc.
4) The body is not susceptible to flash and cavitation damage
5) Good sealing performance, the highest level leakage is VI
6) Long service life.


Application

1) RV 502 control valve is suitable for high temperature, high pressure, high pressure difference, etc.
2) To eliminate the valve differential, the pressure balance valve core and, multiple throttling system have a very high resistance to abrasion (caused by the expansion of fluid and steam). This ensures low noise.
3) The application area of RV502 valve is the continuation of RV 210 control valve to RV235 control valve series. This valve is particularly applicable to metallurgy, nonferrous metals, petrochemical, electric power, paper making, as well as natural gas and other industries.

Process medium

RV502 control valve is designed to regulate the gas, liquid and steam flow and pressure. Usually, the medium includes superheated steam, saturated steam and no special requirements of the valve material medium. For other medium application, please consult the manufacturer as the body material is related to the process medium.

Differential pressure

Taking into account of the pressure balance valve and actuator driving force, when in high differential pressure condition, the application of valve is not subject to media pressure but by the restriction of the throttle system. Using the valve core with a hole and the valve cage with a hole, the maximum recommended differential pressure for each stage of the multi-stage decompression is 5.0Mpa. About the pressure ratio and other equipment specifications, please consult  postmaster@wtindustrialeqpt.com for more information.

 

Maximum allowable working pressure is in accordance with EN 1256-1. Refer to below table [Mpa]

Installation
The control valves installation must make the media flow direction and the arrow marked on the valve body in the same direction. As long as the actuator is not under the valve body, the valve can be installed in the pipe horizontal direction, vertical direction, inclined direction or any directions.
