A Base ISO5211

The top flange, with integrated centring, allows direct installation of the actuator.

B

V-RingThe seal, fitted on the top flange, allows the protection of the shaft line from the outdoor environment.

C

BearingsThe bearings guarantee the perfect stability of the shaft line regardless the pressure conditions.

D Shaft

• Equipped with a foolproofing system which guarantees the correct assembly of the disc;

• Dry shaft design: no contact between the shaft line and the fluid.

E Body

Available in several material grades, the one-piece body design gives it excellent mechanical properties.

F

Seat

The specific design guarantees the watertightness :• bidirectional thanks to the

mechanical anchorage in the body in low and high pressure;

• external without the use of additional gasket on the piping flanges;

• of the shaft line without any additional sealing.

Its great resistance in time is due to a continual demand with French quality partners.Under severe conditions, the easy replacement allows the valve to find back its original characteristics.

G Butterfly

The lenticular profile and the spherical diameter, make it perfectly suitable for all applications, especially abrasives.The absence of a dead-space is a guarantee of safety in the food processing applications.

H Plug

Protection of the shaft line against external pollution.

Approvals

Performance

The maximum pressures and temperatures depend on the pressure / temperature ratio and the characteristics of the fluid.

Technology Concentric and bi-directional butterfly valve.
