Certified Factory Direct Supply Metal Sealing Ball Valve For High
Temperature Fluid
Product Description
The sealing surface of the valve seat is stellite alloy or other
alloy steel, and the sealing surface of
the ball is made of nitriding or surfacing alloy, hard chrome
plating, vacuum coating - tungsten titanium
alloy and Stellite and other forms. Pipeline transportation with
friction dust, slurry, and solid foreign matter
mixed in, has quite high wear resistance and long service life.

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.
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.
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.
Many operate modes
Our metal sealing ball valve can match various operating mechanism
according to the valve size and intended use.
