Product Description

Seeko is one of the leading China Metal Seats Ball Valve manufacturers, welcome to inquiry Metal Seats Ball Valve from our factory.


Seeko 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 Seeko ball processing technical,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.

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.

The most economical point lies in that Seeko metal to metal seat ball valve selects diffent seals according to different working condition.

Seeko metal seat ball valve with high hadness 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.
