Butterfly Valve

The ATHENA is a single seat upslream pressure balanced equilibrium ball float valve, which aulomatically controls the conslant level of a tank or reservoir, regardless of upstream pressure variations, ancl shuts off when the maximum levet is reached. Thanks to its exclusive technology ATHENA brings the concept of reliability and performance to the highest standards.

• Body in ductile cast iron with three ways, allowing the installation both with an angle or a globe pattern, containing an interchangeable sealing seat and piston in stainless steel and a guiding bush in bronze.
• Mobil€ block composed of the main shaft, obturator, gasket retainer and piston featuring a unique self-cleaning technology (pat. pending) to reduce the accumulation of dirt and maintenance operations.
• The lever mechanism, in zinc-plated or stainless steel, is obtained from a double rod (single rod for DN 40/50/65) which, by means of pivots, puts the shaft in communication with the float which imparts the movement allowing the opening or closing of the valve.
• A large float in stainless steel AIsl 304/316 is connected to the lever mechanism by means of a stainless steel pipe, onto which it exerts a vertical force.
• The valves modulates and throttle the inflow proportionally to the consumption, accuracy and perfect water-tightness is guaranteed also with low pressure values.
• Thanks to the upstream pressure balanced seat the movement of the obturator and valve performance is not affected by upstream pressure fluctuations, transient and unwanted surges are therefore avoided.

• Water distribution systems.
• Fire protection storage tanks.
• lrrigation systems.
• Whenever the constant level regulation and control function is required.
