Request information
4900 Butterfly Valve Sandwich
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: "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.

Gasket: EPDM according to FDA 177.2600
Internal surface finish: Ra ≤ 0,8 μm
External surface finish: Machined, Ra ≤ 1,2 μm
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.
