Design Features

Adopting the split-type body and trunnion ball structure, ball will not move under the pressure, and the force generated on the ball will be transmitted to the upper and lower bushings, without being transmitted to the valve seat on the outlet side during operation, so as to avoid excessive pressure on the valve seat and damaged seat.

The inlet end of the double valve seat is sealed, and the two valve seats can independently cut off the fluid at the inlet end to realize the double blocking function of the valve.

The ball and the valve stem are designed and processed in an integrated manner to ensure the ball and stem in the centre line of valve, and avoid the valve stem disengagement by the frequent opening.

The Inconel X-750 spring or high temperature resistant Viton ring be used to provide the initial sealing force of the valve, and the unique sealing structure ensures that no ash and dust enter the spring range, ensuring reliable floating of the valve seat and sealing with the ball.

The valve seat has the self-scraping function due to hard alloy material, then realize the self-cleaning of the spherical surface while the valve is opened, and prevents the ash being blocked on the sealing surface of ball.

The metal remelting technology is used to reliably re-melt the nickel-based cemented carbide with the ball and seat base. The bonding force is obviously superior to other methods, which can effectively prevent the peeling of the hard alloy layer, The reasonable hardness difference between seat and ball is designed to ensure a long service life, and the sealing effect much better.
