Please inform us of the accurate nominal size, pressure class, medium, temperature, material, actuator and other parameters, before consulting or purchasing the product. Thanks!
The valve whose sealing seats (i.e. the sealing surface of the valve seat and the sealing surface of the ball) are made of metal material is called metal seated ball valve. Product features:
Long service life
The sealing surface of the valve seat is stellite alloy or other alloy steel, and the sealing surface of the ball body is nitriding treatment or hard facing alloy, hard chromium plating, vacuum coating - tungsten titanium alloy and Stellite, etc.; metal seated ball valve is applicable for the pipeline transportation of various high friction dust, slurry and solid foreign matters, it has quite high friction resistance and long service life.
High precision ball • high sealing valve seat: Metal seat, poor sealing is its weakness. The metal sealed ball valve developed by our company has very high sealing performance. The valve seat is pre pressed by spring to ensure the tightness under low pressure. The high pressure seal is guaranteed by the piston effect of the valve seat. The most important thing is the unique ball processing technology of our company to ensure the high precision (roundness) of the ball. Advanced valve seat structure and high-precision ball are the main factors to form a tight seal, and also greatly reduce the operating torque.
Metal seats for a wide range of applications: Our metal sealed ball valve has a high hardness metal seat, which is suitable for high temperature fluid, high friction dust, slurry, medium containing solid foreign matter mixing, etc. almost all fluids can be used.
Features of ball valve: Compared with gate valve and globe valve, our metal seat ball valve with more features has all the features of ball valve, with small flow resistance, and can be closed quickly when the valve rod is rotated 90 °. It is easy for manual and automatic conversion and automatic control.
Ideal valve for safety, fire and static protection
Metal valve seat, resistant to high temperature of 500 ℃, with natural fire and anti-static function.
Economical material combination
