Introduction

Pneumatic V-shaped ball valve is manufactured by new series high elasticity&heat-resisting material and special technology for heating processing,disc sealing for sealing pair,having good abrasive resistance,low friction,excellent sealing performance and long working life.It could close tight just needs 90°rotation and little driving torque.

It is suitable for regulating or cutting off water,solvent,acid and natural gas,also suitable for rigorous media like oxygen,hydrogen peroxide,methane and ethylene.V-shaped notch and seat forms to wedge structure when the valve closed,avoiding sticking caused by dirt in ball and seat.Widely used to regulate  fiber mixed slurry,sewage, particle mixed media,high-temperature steam and dry gas.

Types of different structures

Float pneumatic V-shaped ball valve

Float type,suitable for low pressure condition.The ball will move and coarct to sealing surface at outlet end by media pressure.

Fixed pneumatic ball valve

Fixed type will not move by media pressure.It has float seat and the seat will move and push seal ring to ball tight by media pressure.Normally there is bearing equipped to lower shaft and arm-shaft that reduces operating torque.It is suitable for large-bore and high pressure valve.

Elastic ball pneumatic ball valve

Ball and seat seal ring are both manufactured by metallic materials  and sealing pressure ratio is so high that need external force to finish sealing.It is suitable for high-temperature and high-pressure media.

Types of channel position

Straightway type,three way type and right-angle type
