INOXPA Butterfly Valve Sandwich 4900
Sandwich butterfly valves, whether manually or automatically operated, can be used in most liquid product applications in the food-processing, pharmaceutical and chemical industries. The design allows to easily instal or remove the valve without separating the pipes.

Product Description
Application
Operating principle
The butterfly valve can be operated automatically through an actuator or manually with a handle. The handle blocks the valve in the “open” or “closed” position, although there are also other models with intermediate positions.The actuator transforms the axial movement of the piston into a 90º rotary movement which it transmits to the disc.
Design and features

- Compact and robust design.
- Multi-position handle as standard feature for valves up to DN-100/4″.
- Two-position handle as standard feature for valves starting from DN-100/4″.
- Low pressure losses.
- Bodyhalves interchangeable with any connection type.
- Connections: DIN 11850.
- Traceability of components.
