Metal To Metal Sealing Ball Valve For High Temperature Conditions
Product Description
The ball surface adopts special surface hardening treatment, the valve seat adopts hardfacing hard alloy, so in the valve opening and closing process can withstand the medium scouring very well, especially suitable for dry solid particles and abrasive medium. Except for special surface treatment of ball and seat surfaces, flexible graphite and metal wound gaskets are used in other sealing materials.Therefore,it can be used under dry high temperature and high pressure conditions, with fire-proof function.
Technical Parameter
Long life time and seat Metal Sealing Ball Valve surface is made of stellite alloy or other alloys and the ball sealing surface is nitriding treatment or surfacing alloy, hard chromium plating,vacuum plating tungsten titanium alloy and other stellite forms ; for all levels temperature and high friction dust,
slurry, solid foreign body mixed transportation pipeline, it has the very high abrasion resistance and long service
life. High precision ball and high sealing seat The weakness of metal seat is poor sealing, but we can produce
metal sealing ball valve with high sealing performance . By the spring preloads valve seat to ensure the low
pressure sealing, the valve seat piston effect guarantees high pressure sealing performance, the most
important is we have the special sphere processing technology to assure high precision (roundness). The
advanced seat structure and high precision ball are the main factors of high sealing performance, which also
can reduce operating torque to a large extent. Wide appliacation valve seat Half opened soft valve seat will damage the valve seat, which can
not use for some medium and narrow temperature range. Our metal sealing ball valves have high hardness
seat that suitable for high temperature fluid, high friction dust,slurry, containing impactor medium, mixed
solid foreign matter etc, almost all of the fluid. Have all ball valve features Compared with gate valve and globe valve, our metal seat ball
valves have more features, small flow resistance, fast closure by operating stem to turn 90
degrees,easily switching between automatic and manual that is convenient for automatic control. Safe - fireproof - antistatic valves The metal seat can resistant to 500 degrees high temperature and
also have the natural fireproof and anti-static function. Most economy combined matieral Our metal sealing ball valve can select different sealing pair to
realize the most economy according to different working conditions. Company Profile Weite
