APPLIATIONS

It is specially suited for the confrol of fluid with fiber and ÿÿÿÿÿgraininess,such as the pulp production,sewage treatment and oil ÿÿÿproduct pipeline.
It is mainly used in such industeies as gas,chemical industry, ÿÿÿÿÿpapermaking,power,light industry and water tretment works.
 

FEATURES:

The V-shaped path is charactcristic of big adjustable ratio and ÿÿÿÿpercentage flow equal smooth regulation of that realizes the ÿÿÿÿÿpressure and flow.
ZSHV SERIEC PNEUMATIC V-SHAPED BALL VALVES Big nut flexible autocompensation structure is adopted which an ÿÿÿÿeffectively adjust the sealing surface of valve seat and valve core ÿÿthus ahieuing a good sealing perforance.
Its of the valve core and valve seat eccentric structure can reduce ÿÿthe wear.
