Butterfly Valve Sandwich 4900

Application

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.

Operating principle

The butterfly valve can be operated automatically through an actuator or manuallywith a handle.
The handle blocks the valve in the "open" or "closed" position, although there are alsoother models with intermediate positions.The actuator transforms the axial movement of the piston into a 90º rotary movementwhich it transmits to the disc.

Design and features

Design: "between flanges".
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.

Options

AISI 304L valve.
Gaskets: NBR, VMQ or FPM.
Two sizes for two-position handle.
Handles: two-position, lever, micrometric, with safety lock, etc.
Electric actuator or single- or double-acting actuator,


 the size is determined by the operating torque of the valve.
