Pressure-Activated Bonnet Sealing
The pressure seal bonnet utilizes internal system pressure to strengthen the seal between the bonnet and body. As operating pressure increases, sealing performance improves automatically, significantly reducing the risk of external leakage.
Designed for Ultra-High Pressure Applications
Specifically engineered for Class 600 to Class 4500 pressure ratings, making it the preferred solution for high-pressure steam, boiler feedwater, and critical power plant services.
Reduced Bolt Load Compared with Bolted Bonnet Designs
The pressure seal structure minimizes reliance on bonnet bolting, reducing bolt stress and maintenance requirements while improving long-term joint reliability.
Enhanced Safety Under Extreme Temperature Cycling
The self-energizing pressure seal accommodates thermal expansion and contraction more effectively than conventional bolted bonnet valves, ensuring dependable sealing during repeated temperature fluctuations.
