VALVE FEATURES
- Designed by Computational Fluid Dynamics (CFD)
- Metal to Metal Seated design.
- Tight shut-off is obtained by means of a metal-to-metal sealing
- Spring loaded disc design allows mounting in any orientation
- Short stroke length reduces closure time and minimizes water hammer
- Low Pressure drop to avoid Cavitation and turbulence
- Short light weight Disc & Fast closing Spring design protects the piping against sudden Surge
