SBV Metal-to-metal Seated Ball Valve has high intensity ball and seat.It ensures its tightness via spring prepressing seat in case of low pressure. In case of high pressure, the tightness is secured via seat plunger effect. The key point is the original ball processing technology, which ensures the high precision (roundness)and strength of the ball. Advanced seat structure and high precision ball are the main factors of high tightness. Meawhile, it will reduce the valve operation torques.

 

The seat is of overlay stellite alloy surface,and the ball sealing face is of three forms as hard chrome plating, vacuum coating and tungsten-titanium alloy and stellite alloy etc. It has good friction-resistance and long life for pipeline delivery of mediums with various operating temperature, high friction dust, slurry and solid foreign matters mixture.

 

The most economical point of SBV metal- to- metal seated ball valve is different seals according to different working condition.

 

Metal seat is resistant to extremely high temperature of 500 degrees celsius,,with the function of fire and static resistance.

 

SBV metal-to-metal seated ball valve with high hardness metal seat is applicable for high temperature liquid, high friction dust,slurry,transmitter with impacting substances and solid mixtures etc.It is nearly applicable for all liquids.

 

The valve top working flange is designed according to ISO 5211 (if design is allowed),which is convenient for connection and change its operation types. The common operation types are manual (Lever/Gear Box), electrical, pneumatic and pneumatic/hydraulic.
