The peumatic daphragm cntrol vlve sries consists of pnematic multi-spring diaphragm actuator, low folw resistance straight-through control valve, and high precision electro-pneumatic valve positioner. The valve uese the compressed air as the driving prwer, receives standard 4— 20MA control signal to change valve opening and relize the adjustment of pressure, temperature. Flow, liauid level and other technological parameters.
Main Performance Parameters

It is widely applied in the automatic control system in electric power, petroleum, chemical industry, metallurgy, light industry, college teaching and scientific research equipment and other industries.
RV Ball Valve Series
The ball valve series consists of O type or V type ball valve and electric or pneumatic actuator. The electric and pneumatic actuators indude regulating type and switching type. The regulating type receives 420MADC control signal and feeds back 420MADC valve position signal. The switching type (electric)is allocates inside with the resistance signal and optional dry contact. The switching type(pneumatic)can be equipped with solenoid valve, limit switch and other accessories.

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.
