Complete range of industrial valves for various applications
Valves Fundamentals:
- Isolation Valves: Used to completely stop fluid flow (Ball, Gate, Plug valves)
- Regulation Valves: Used to control flow rate (Globe, Needle, Control valves)
- Check Valves: Prevent backflow in pipelines (Non-Return Valves)
- Strainers: Protect equipment by filtering debris from fluid streams
