Application & Operation
Lift check valves automatically prevent backflow by responding to pressure changes in the pipeline. The disc lifts from the seat as inlet pressure increases, while pressure differentials between inlet and outlet sides cause the valve to close. Back pressure maintains the disc in the closed position for effective sealing.
These valves are typically installed in horizontal flow applications but can be configured for vertical installation with spring assistance. The lift check design provides superior shutoff capability and tighter sealing compared to swing check valves.
Product Features
- Body and cover constructed from high-quality casting steel with robust sections
- Body seat ring and disc precision-machined to close tolerances for smooth operation and accurate seating
- Enhanced sealing performance compared to swing type check valves
- Optional spring configuration available for vertical installation requirements
