European & American Standards
All materials used are of high technology ; this allows to be proof against high pressure , water hammer and allows to meet all the international standards.
The seals subjected to the compression set are nontoxic and shape-retaining.
The discs, in syntherized ceramic at low friction coefficient, allow a movement extremely soft even after several years of use.
The product recognizable by the high flow rate and the low noise to be according to the various international bureaux.
1/2" classic headwork
Perfectly tight: the tiresome leakages due to dripping are eliminated.
Exceptional strength: brass drive and internal stops are of reinforced section.
Exceptional wear: during the Life tests these valves exceeded the 500.000 open/closing cycles in cold water ~20°C) and the 200.000 cycles in hot water ~90°C) WITHOUT mesaurable wear, malfunction or breakage of parts.
No shape deformation throughout temperature range.
Ease of turning: the high manufacturing precision, and quality of the components with continuous process inspection guarantees 100% smooth running.
Short turning movement: only 90° (1/4 turn) or 180° (1/2 turn) to fully open or close the tap.
The absence of wear from threaded moving brass components eliminates internal vibrations.
Always constant water flow from rotation of the tap.
Perfect hot and cold water mixing: all the variations due to the deformation of the rubber washers are eliminated.
