FLDI/ SP – Closure Speed Control Valve

The FLDI/ SP – Gradual and Regulated Closing Speed Control Valve prevents pressure surges that can occur with fast valve closures leading to potential damage to pipes, valves, or other components. It does so by automatically and dynamically self-adjusting its closure speed, ensuring smooth operation and protecting the entire system.
Notes:
1. An optional solution is to install a quick relief valve (QR) at the bypass.
2. To prevent backflow, a check valve (CV) can be incorporated (FLDI/ SP/ CV).
