V type ball valve
V type ball valve is suitable for use on various kinds of pipelines of Class150 ~ Class300, and PN16 ~PN40. There are two kinds of applications for V type ball valve according to customers' 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
Three way Ball Valve
Three way ball valves are suitable for use on various kinds of pipelines of Class150~Class300, PN16~PN40 for switching, dividing, and combining medium flow, of which the operation manners include manual, worm gear, pneumatic or electric actuators, connection manners are in general of flanges. As required by customers, the other type of connection is available too.
Metal to metal sealed three way ball valve
The ball and seat of metal to metal sealed three way ball valve are employing advanced techniques of nickel base alloy spray welding ( of which hardness being >=HRC60 ), ultro-sonic stellite spray coating (max. hardness of HRC75 ), and specially hardening treatment etc., featuring reliable tightness and longer service life, being particularly used for the medium with ash dregs and solid particles. Application temperature of general products is <= 200 Degrees Celsius. As specially ordering, application temperature may reach 425 Degrees Celsius (carbon Steel) or 540 Degrees Celsius(S.S., CrMo steel, CrMoV steel).
