Frequently Asked Questions
It’s a specialized, heavy-duty swing check valve engineered for very high-pressure systems. Its defining feature is a unique bonnet (or “cover”) that uses the system’s own internal pressure to create an increasingly tighter seal. This ensures exceptional leak prevention where it matters most.
Think of it as the upgrade for extreme duty. Choose a Pressure Seal Cover design when your application involves very high pressures (typically Class 600 and above), high temperatures, or critical services in industries like power generation, oil & gas, and petrochemicals. It’s for when system integrity and safety are paramount.
Unlike a standard gasket or bolt-based seal, this design features a specially shaped bonnet gasket. As the system pressure rises, it pushes the bonnet assembly upwards, which in turn forces the gasket to wedge more tightly against its sealing surfaces. Simply put, higher pressure creates a stronger, self-energizing seal.
The biggest advantages are superior safety and reduced maintenance. The self-sealing action provides a guaranteed leak-free performance at high pressures, protecting people and processes. This robust construction also offers exceptional durability and long service life, minimizing the need for interventions and downtime.
They are ideal for critical high-pressure lines where backflow prevention is essential. Common applications include main steam lines, boiler feedwater systems, high-pressure process lines in refineries, and other demanding services in power plants, offshore platforms, and chemical plants.
Yes. As a leading manufacturer, IPC specializes in engineering valves for specific project demands. We can provide expert guidance on selecting the correct size, pressure class (like #150 to #2500 and beyond), and material specifications (such as forged or cast steel grades) to match your exact service conditions.
