RV ZQSN electric double-seat control valve is an execution unit in an electric unit conbination meter, and is one of key links in a production process automatic regulating system. The regulating modes include a switching mode and a regulating mode. A regulating type inter servo amplifier receives standard 4~20m ADC(or 1~5V DC) control signals, and controls a motor to rotate positively and negativelu to make a valve stem to drive a valve plug to correspondingly move to open and close the valve, thereby realizing regulation and control of the technical parameter like pressure, flow, temperature, liquid level, etc.
The RV ZQSN electric double-seat control valve has the characteristics og large flow capacity and small unbalanced force, and can be broadly applies intp the automation control systems of industrial production process like power station, chemical industry, oil, metallurgy, building materials, water treatment, heat supply, light industry, etc.

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.
