Technical Specifications
SPECS Pressure Seal Bonnet(PSB) Gate Valves are designed for pressure range from class 900Lb to class 2500lb, working temperature -29～425℃ (carbon steel) or -29～500℃ (stainless steel) on small-diameter pipelines, used to shut off or connect the medium in the pipeline, different selection The material can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc.
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-cut off 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.
