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.

Feature
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.
