Outline
RV cylinder type pneumatic control valve is accordance with intemational standard (ISO6431). QGB pneumatic actuator is powered by compressed air and outputs thrust or pull force through rectilinear motion of piston and piston rod to open or close the valve with linear travel. The pneumatic control valve is provided with an intelligent electro pneumatics valve positioner to receive a 4-20ADC control signal of adjuster from computer, and at the same time outputs a 4-20 ADC valve position feedback signal corresponding to actuator travel in order to adjust the opening of valve by remote control. The pneumatic actuator may adopt double acting form: Spring return single action form, hand wheel from, 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.
