Butterfly Valve U Type
This model of butterfly valves are used for control and on/off operations.
It’s the wafer type valves,but the designed U type flanges facilitate the pipeline centering and installation.
Usually they are used in application fields such as,water supply and treatment,the metal industry,power generation,pulp and paper,mining,shipbuilding,environmental and mechanical engineering.
Further features and benefits are:
- ISO 5211 mounting pad compatible for various type of actuators;
- Pinless disc and stem,easy replacement of valves parts.
- CNC machined and manually polished disc edge, ensures long life and low torque.
- Anti-blow out shaft and lockable handle lever and gearbox
