Design & Performance Features
- It is a full bore straight through, give high flow performance with
minimum turbulence, while giving 100% leak tight closure.
- Perfect sealing and longer diaphragm life due to weir design.
- Valve is self cleaning with no pockets, recesses, corners,
grooves or sharp edges in the direction of flow.
