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.
