Product Description

V type ball valve Application V type ball valve is suitable for use on various kinds of pipelines of Class**0~Class**0, and PN*6 ~ PN*0. There are two kinds of applications for V type ball valve according to customers&#**9; different requirement. One is used for cutting off or switching on the pipeline medium. The other is used as control valve for regulating the medium fow capacity in pipelines. Operation manners for cutting off type V type ball valve include manual, worm gear, pneumatic or electric actuators, where as for regulating type V type ball valve, operation manners are of pneumatic and electric actuators. Of the application for metal to metal sealed v type ball valve, the temperature is in general <=**0 Degrees Celsius. As specially ordering, the application temperature for metal to metal sealed v type ball valve can be <=**5 Degrees Celsius (carbon steel valve body ) or <=**0 Degrees Celsius (valve body of stainless steel, CrMo steel, and CrMoV steel ). For Soft Sealed V type ball valve, the application temperature is in general <=**0 Degrees Celsius (reinforced PTFE seat). Connection type for V type ball valve is of wafer flanged connection. Features 1. For V type 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 metal sealed ball valve, such as nickel base alloy by spraying welding (for hardness >=HRC*0), stellite alloy by ultra-sonic spraying coating (for max.hardness >= HRC*0) , and specially hardened material etc.
