| V Type Ball Valve Wafer / Flanged Connection For On/Off or Regulating |
Application: V type ball valve is suitable for using on various kinds of pipelines of Class150~Class300, and PN16~PN40. There are two kinds of applications for V type ball valve according to customer's different requirements. One is used for cutting off or switching on the pipeline medium. The other is used as control valve for regulating the medium flow capacity in pipelines. Operation manners for cutting off type V type ball valve include manual, worm gear, pneumatic or electric actuators. For regulating type V type ball valves, operation manners are of pneumatic or electric actuators.
Of the application for metal to metal sealed V type ball valves, the temperature is in general ≤200ºC. As specially ordering, the application temperature for metal to metal sealed V type ball valve can be ≤425ºC(carbon steel body) or ≤540ºC(valve body of stainless steel, CrMo steel, and CrMo V steel). For soft sealed V type ball valves, the application temperature is in general≤180ºC(reinforced PTFE seat)
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.
2. If 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 seperately for the ball and seat surface of metal to metal sealed ball valve, such as nickle base alloy by spraying welding(for hardness≥HRC60), stellite alloy by ultra-sonic spraying coating(for max. hardness≥HRC70), 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 type V ball valve, its regulating scope available is wide and its regulating accuracy is high.
