Key Features of Pressure Seal Bonnet Gate Valve

Pressure-Activated Sealing Mechanism: The bonnet is designed to seal more tightly as the internal pressure increases. This self-tightening feature ensures that the valve remains leak-free even under extreme conditions.
Simplified Design: Unlike traditional gate valves that rely on bolts and flanges to secure the bonnet, the PSB gate valve eliminates these components. This simplification not only streamlines the installation process but also reduces the overall weight of the valve.
High-Pressure and High-Temperature Applications: The PSB gate valve is particularly well-suited for environments where high pressures and temperatures are common. Its robust design ensures reliable performance and longevity in such challenging conditions.
Reduced Maintenance: The absence of bolts and flanges means fewer potential points of failure. This design reduces the need for frequent maintenance and inspection, thereby lowering operational costs over time.
Enhanced Safety: The tight seal provided by the pressure seal bonnet joint minimizes the risk of leaks, which is crucial in applications involving hazardous or high-pressure fluids.
