4800 Butterfly Valve

4800 Butterfly Valve


Product Description

Sanitary butterfly valves, whether manually or automatically actuated, can be used in most liquid product applications in the food-processing, pharmaceutical and chemical industries.

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″.
Several models of easily interchangeable manual handles and pneumatic or electric actuators.
Low pressure losses.
Body halves interchangeable with any connection type.
Connections: DIN 11850.
Traceability of components.
