Lift Type Check Valves (NRV)
A Lift Type Check Valve features a vertically moving disc or plug that lifts off its seat to allow flow in one direction and drops back to prevent backflow. Its design ensures effective one-way flow control with minimal pressure drop. Ideal for applications requiring reliable backflow prevention and smooth flow management.
Features
- Vertical Movement: The disc or plug lifts off the seat to allow flow and drops back to prevent backflow, ensuring one-way flow control.
- Minimal Pressure Drop: Designed to offer low resistance to flow, maintaining system efficiency.
- Reliable Backflow Prevention: Effectively prevents reverse flow and potential damage to the system.
- Simple Design: Features a straightforward mechanism with fewer moving parts, facilitating easy installation and maintenance.
- Durable Construction: Built to withstand high pressures and various conditions, providing long-lasting performance.
