Check Valves
Automatic prevention of reverse flow
Check Valves
Overview
Check valves protect equipment and pipelines by allowing flow in one direction and automatically preventing backflow. A range of designs — swing, dual-plate, lift and piston — covers everything from low-pressure water lines to high-pressure steam systems.
Key Features
- Automatic, non-return reverse-flow protection
- Swing, dual-plate, lift and piston designs
- Low cracking pressure, minimal slam
- Renewable seats and discs
- Bolted-bonnet and pressure-seal constructions
Applications
Pump discharge Boiler feed Oil & gas Power Water systems
