METAL SEAT BALL VALVE/HARD SEALING BALL VALVE/METAL TO METAL BALL VALVE

1.High precision ball& High tightness seat
Metal seat ball valve has high tightness,it ensures the 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 OVIKO ball processing technic,which ensures the high precision of the ball(roundness).Advanced seat structure and high precision ball are the main factors of high tightness.At the same time,it extremely reduces operating torque. 2.Long life ball&seat

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