Pressure-Activated Bonnet Sealing
The pressure seal bonnet utilizes internal line pressure to enhance the sealing force automatically, providing superior sealing performance as system pressure increases.
Designed for High-Pressure & High-Temperature Service
Specifically engineered for severe operating conditions in ASME Class 600–2500 applications where conventional bolted bonnet valves become less efficient.
Reduced External Leakage Risk
The self-energizing pressure seal design minimizes bonnet gasket stress relaxation, significantly reducing the possibility of external leakage during thermal cycling.
Compact Bonnet Construction
Eliminates the need for large bolted bonnet flanges, resulting in a more compact, lighter, and space-saving valve design for high-pressure piping systems.
Excellent Thermal Expansion Compensation
The pressure seal joint automatically accommodates thermal expansion and contraction, maintaining reliable sealing integrity under frequent temperature fluctuations.
