1.600.000 cycles
Bonomi Group has always guaranteed a high product quality standard thanks to the synergy and integration of the different engineering departments of the group's companies.
The industrial plant engineering sector is characterized by many applications, including very complex ones, where product quality and high performance are a guarantee for the continuous operation of production lines. 
Valbia and Ghibson have combined their expertise to offer the market an automation package consisting of a "double eccentric" butterfly valve (HD Series) and a single or double-acting pneumatic actuator (82 Series).
The package was tested for reliability and robustness under heavy duty service conditions. The test was carried out at a temperature of 20°C through repeated cycles at 3-second time intervals and was voluntarily discontinued, given the excellent results, after about 1,600,000 cycles in the absence of signs of wear. 
After the test was finished, the actuator-valve combination was subjected to visual inspection, in-line testing, water testing, and torque detection. The valve was also bench tested with evidence of no disc and seat leakage. 
All inspections showed that the actuator and valve were in perfect condition. 
An excellent performance, that of Valbia and Ghibson, with an extraordinary result that further demonstrates Bonomi Group's strong commitment to engineering, manufacturing and installing efficient and innovative products that meet all market requirements, where safety and durability are essential features.
