Long service life of the ball and valve seat
As the stellite alloy or other alloy steel valve seat sealing
surface, the sealing surface of the ball body for nitriding
treatment or surfacing alloy, hard chromium plating,vacuum plating
tungsten titanium alloy and other forms of Stellite; all levels
oftemperature and high friction dust, slurry, solid foreign body
mixed transportation pipeline, has the very high abrasion
resistance and long service life.
High precision, high sealing ball valve seat
The metal valve seat, sealing difference is its weakness, sealing
performance is very high Division I developed metal sealing ball
valve. By the spring preload valve seat, to ensure the low pressure
sealing, pressure sealing guaranteed by seat piston effect,one of
the most critical is the sphere processing technology of our
original sphere,ensure high precision (roundness). The seat of
advanced structure, high precisionball constitute the main factors
of tight sealing, at the same time and reduce operating torque.
Application of a wide range of metal seat
Soft seat general, half open state is easy to damage the valve
seat, and some fluidcan not be used, narrow temperature range, use
limited. Division I metal sealing ball valve high hardness metal
seat, suitable for high temperature fluid, high friction
dust,slurry, containing impactor medium, solid foreign matter
mixing, almost all of the fluidcan be used.
All the properties of both the ball valve
Comparison of gate valve, cut-off valve, with more features for our
metal seated ball valve, all characteristics of both the ball
valve, the flow resistance is small, the operation of the valve
stem rotation of *0 DEG can realize fast closure, conversion of
manual, automatic and easy, easy automation control.
The most ideal valve safety fireproof anti electrostatic
The metal seat, resistance to high temperature of **0 DEG C limit,
has the natural fire and anti-static function.
The most economical material combination
Division I metal sealing ball valve, used according to different
conditions, the selection of sealing different, can realize the
reasonable selection of the most economic.
The arbitrary choice of the mode of operation
Division I metal sealing ball valve, according to the valve size
and purpose of use, can choose a variety of operating
mechanism.
