The Pressure Sealed Bonnet Gate Valve adopts a top-mounted structure, which reduces the connection bolts of the valve body under high pressure and large diameter conditions, enhances the reliability of the valve and can overcome the influence of the system’s own weight on the normal operation of the valve. The Pressure Sealed Bonnet Gate Valve is mainly used in some high-pressure working conditions, which are pre-tightened by bolts. As the working pressure increases, the wedge seal in its structure becomes tighter and the sealing performance is better. With the help of physical pressure, the valve can achieve self-cutoff without manual treatment.

Its advantage lies in its ability to control itself, and its self-closure is excellent.

Mainly used in high-pressure working environment and large-scale industrial equipment, widely used in coal chemical industry, petrochemical industry, rubber, papermaking, pharmaceutical and other pipelines as a shunt or flow switching device.
