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.
The metal seat, poor sealing is its weakness, sealing performance is very highDivision 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.
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,paste, containing impactor medium, solid foreign matter mixing, almost all of the fluidcan be used.
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 90 DEG can realize fast closure, conversion of automatic and manual easily, convenient for automatic control.
The metal seat, resistance to high temperature of 500 DEG C limit, has the natural fire and anti-static function.
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.
Division I metal sealing ball valve, according to the valve size and purpose of use, can choose a variety of operating mechanism.
