This valve uses the Compressed air as the working power, pushes the piston, drives the disc to make the displacement perpendicular to the fluid, and realizes the goal of switching or closing the valve. Structural seat sealing surface surfacing stainless steel copper or carbide, after finishing, wear-resistant, corrosion-resistant, high temperature. Gate sealing ring is surfacing alloy, sealing red ah, easy replacement and maintenance. The cylinder is made of seamless steel tube, the inner surface is plated with corrosion-resistant hard chromium and polished, and has the characteristics of small friction, not easy to rust, high hardness and long service life. The surface of piston rod is quenched, tempered and nitrided with instant noodles. It is abrasion-resistant and high temperature-resistant. The oil-resistant rubber o-ring is adopted in the cylinder, which has reliable sealing performance and is more convenient for maintenance. Features can be achieved remote control, centralized control and automatic control. Reliable sealing performance, easy replacement and maintenance. According to different use conditions, choose different diameter and stroke of the gas (liquid) cylinder, the use of a wide range.
