RV ZJHP(M) pneumatic single-seat(sleeve) control valve consists of a pneumatic multi-spring diaphargm actuator and a hydraulic resistance straightway single-seat valve(sleeve valve); The upper valve cover of the single-seat valve is provided with a valve stem guiding stucture and the valve plug is a plunger structure; Compared with a common single-seat valve, it has the characteristics of small size, light weight and big flow, etc, which is suitable for occasions with large flow and strict requirements on leakage volume. Compared with a common sleeve valve, ZJHM type minitype sleeve valve has the advantages of smaller size(smaller by1/3), lighter weight(lighter by1/3) and bigger flow(bigger by 1/3), which can be broadly applied into industrial process automatic control system requiring low noise and large pressure difference.
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.
