In a RV ZQSF(H) electric three-way diverging(converging) control valve, a three-way diverging(converging) valve is equipped with a PS series actuating unit; A servo system is arranged inside an electric actuator, which does not need to be additionally equipped with a servo amplifier and can control moving and rotating through input control signal(4~20m ADC or 1~5VDC)single-phase power source, thus realizing the control of parameters like pressure, flow, temperature, liquid level, etc. The valve adopts a balanced valve plug stucture, has the characteristics of good plug stability, no easy vibration, low noise, large allowable using pressure difference, simple connection, etc, and can be broadly applied into the industrial auomatic control systems of industries like electric power, metallurgy, oil, chemical industry, light industry, environmental protection, etc, which have large flow coefficients and strict requirements on leakage volume.

As one of the four subsidaries of Shanghai River-wave International Group Co., Ltd, Shanghai River-wave Fluid Machine Manufacturing Co., Ltd. Was accredited with Shanghai Hi-tech Enterprise in 2010. The application of the first-class fine machining center, CNC machine tools as well as control valve flow characteristics testing and monitoring center makes it highly effective for us to provide users with flow curves, flow characteristic curves of the control valve and other curves related to pressure, flow and temperature by means of microprocessor control.
Currently, Shanghai River-wave put its major focus on manufacturing control valves, regulating valves, PSA pneumatic sequencing valves, electric control valves, ball valves, butterfly valves, globe valves and products of other series. We have been proving valves for Germany BASF, Bayer, Shanghai Waigaoqiao Shipbuilding Co., Ltd, Yangzi Petrochemical Co., Ltd. Jiangnan Shipbuilding Works, etc...The company has been granted more than 30 patents. From 2007 to 2011, Shanghai River-wave has been assredited with Contract Honoring and Credit Keeping Enterprise for consecutively four years. Meanwhile, River-wave has obtained the TS National Manufacturing License for Special Equipment and CE Certificate, CCS Certificate for ships, etc.
Core Value of Shanghai River-wave: Satisfied customers, happy employees, assured Stockholder, stainable development.
