• Connection system for solvent weld, threaded and flanged joints • Compact and lightweight construction • High flow coefficient and minimum pressure drop • Internal components in metal totally isolated from the conveyed fluid, with anti-friction disk to reduce friction to a minimum • Modularity of the range: only 5 diaphragm and bonnet sizes for 9 different valve sizes • Handwheel that stays at the same height during rotation • Bonnet fastening screws that screw into the built-in bush preventing the deposit of dirt or impurities • CDSA system (Circular Diaphragm Sealing Angle) used up to DN50, offering the following advantages: - uniform distribution of shutter pressure on the diaphragm - reduction in the tightening torque of the screws fixing the actuator to the valve body - reduced mechanical stress on all valve components (actuator, body and diaphragm) - easy to clean valve interior - low risk of the accumulation of deposits, contamination or damage to the diaphragm due to crystallisation - operating torque reduction
