A640 Ball Valve

Sanitary ball valves A640, whether manually or automatically operated, are used mainly with viscous fluids containing solid particles, and, generally, in applications requiring an unobstructed flow.
Suitable for the food-processing, beverage, wine-making, oil-making, cosmetic and chemical industries.

The ball valve can be operated automatically with an actuator or manually with a handle.
The handle blocks the valve in the “open” or “closed” position. The actuator transforms the axial movement of the piston into a 90º rotary movement which it transmits to the ball.
