AP Pressure Seal Bonnet Gate Valve

As the professional manufacturer, we would like to provide you Taian AP Pressure Seal Bonnet Gate Valve. And we will offer you the best after-sale service and timely delivery. The API Pressure Seal Bonnet Gate Valve is a high-performance gate valve specially designed for high-pressure and high-temperature working conditions, and is widely used in industries such as power, petrochemical, oil refining, natural gas, and nuclear energy. Its core feature is the adoption of a pressure-sealed valve cover structure, which replaces the traditional bolted valve cover and achieves self-sealing under high pressure, thus avoiding the risk of leakage.

Product Description

Specifications

As a professional high quality Taian AP| Pressure Seal Bonnet Gate Valve manufacturer,we will offer you the best after-sale service.The pressure-sealed valve cover of Seal Bonnet Gate Valve uses the medium pressure to push the valve cover and gasket to press tightly, achieving "self-sealing". The higher the pressure, the tighter the seal. Compared with the bolt valve cover design, it is lighter in weight and smaller in volume, making it suitable for space-constrained occasions.AP| Pressure Seal Bonnet Gate Valve is applicable to Class 600 to 3500 (PN100 - PN600), with a temperature range up to 650°C. The valve body material is made of cast or forged carbon steel, alloy steel, stainless steel, and duplex steel, nickel-based alloy, etc. can be selected. The design of the valve plate includes Flexible Wedge, Parallel Slide and Double Disc. The operation methods include manual (handwheel), gearbox, electric, pneumatic or hydraulic actuators
