INOXPA Butterfly Valve 4800


Butterfly valves, whether manually or automatically operated, 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.
