Pressure-sealed Bonnet Gate Valve

Pressure-Sealed Bonnet Gate Valve is a high-pressure industrial gate valve featuring a self-sealing bonnet structure. The internal medium pressure automatically presses the sealing surface, and sealing performance improves as operating pressure increases.

Applications

Pressure-Sealed Bonnet Gate Valve is widely used in power plants, petrochemical facilities, oil refineries, steam systems, hot oil pipelines, and chemical processing industries. It is commonly selected by EPC contractors, engineering companies, valve distributors, and industrial plant operators for critical high-pressure pipeline isolation.

Core Features

1. Pressure Self-Sealing Bonnet Design

The internal pressure enhances sealing force automatically, providing reliable sealing performance under high-pressure conditions.

2. High Temperature & Pressure Resistance

Available materials including WCB, WC6, WC9, CF8, CF8M, CF3, and CF3M provide excellent strength and durability in extreme environments.

3. Suitable for Harsh Media

Designed for applications involving steam, hot oil, and corrosive fluids, ensuring stable operation in demanding industrial systems.

4. Multiple International Standards Available

Available in API, DIN, GOST, JIS, GB, and other standards to meet global project requirements.
