Design & Working Principle
Lift Check Valve Operation
The lift check valve operates on a simple yet effective principle. When fluid flows in the forward direction, pressure forces the disc to lift from its seat, allowing media to pass through. The disc moves parallel to the flow axis, guided by the valve body to ensure proper alignment.
When flow stops or reverses, the combination of gravity, spring force, and reverse flow pressure quickly returns the disc to its seat, creating a tight seal that prevents backflow. This rapid response is critical in high-pressure applications where backflow can cause significant damage.
High-Pressure Performance
The 1500lb pressure class design incorporates reinforced body walls and precision-machined components that work together to contain extreme pressures. The robust construction of this valve makes it ideal for critical applications where failure is not an option.
The spring-assisted closure mechanism ensures positive shutoff even in low-flow or low-differential pressure conditions. This design prevents the “flutter” that can occur in some check valves, extending the service life and improving reliability in your system.
Maintenance Considerations
The valve’s design prioritizes longevity and ease of maintenance. The bolted bonnet construction allows for straightforward access to internal components when service is required. All wear surfaces are hardened and precision-finished to extend service intervals and reduce maintenance costs over the valve’s operational life.
