There are two kinds of applications for V type ball valve according to customers different requirement. One is used for cutting off or switch on the pipeline medium. The other is used as control valve for regulating the medium flow
capacity in pipeline. Operation manners for cutting off type ball valve include manual, worm gear, pneumatic or electric actuators, where as for regulating type V type ball valve, open ball valve, open manners are of pneumatic and electric actuators of the application for metal sealed V type ball valve, the temperature is in general 200 .As specially ordering, the application temperature for metal to metal sealed Eccentric Semi-Ball Valve can be 425 (carbon steel valve body) or 540 (valve body of stainless steel, CrMo steel, and CrMo V steel).For Soft Sealed Eccentric Semi-Ball Valve, the application temperature is in general 180(reinforced PTFE seat).

Connection type for Eccentric Semi-Ball Valve is of water flanged connection.
Features
1. For Eccentric Semi-Ball Valve, the bevelling spring or pillar spring loaded movable seat design has been employed, which is reliable in seal and of long service life as
there in no such problems as clenching or disjointing.
2. It features the function of slipping between the ball with cutting edge and metal seat, which is particularly suitable for the medium containing fibre, solid particles,
thick fluid, and so on.
3. As per different working conditions of customers, several kinds of advanced techniques have been employed separately for the ball and seat surface of metal to meta l sealed ball valve, such as nickel base alloy by spraying welding (for hardness HRC60), stellite alloy by ultra-sonic spraying coating (for max. hardness RC70), and specially hardened material etc. ,which are suitable for many kinds of critical working conditions.
4. When the valve is fully open, flow capacity is big, pressure loss is small, and the medium would not deposit in the body cavity.
5. Being impact in structure and extensive in common use, the cutting off V type ball valve features perfect sealing property and may replace gate valve, globe
valve and general ball valve. For regulating V type ball valve, its regulating scope available is wide, and its regulating accuracy is high.
