DIALOCK® diaphragm valve with female union ends for socket welding, metric seriesDIALOCK® 2-WAY DIAPHRAGM VALVE• Connection system for solvent weld, threaded and flanged joints• Optimised fluid dynamic design: maximum output flow rate thanks tothe optimised efficiency of the fluid dynamics that characterise the newinternal geometry of the body• Internal components in metal, totally isolated from the fluid and externalenvironment• Modularity of the range: only 2 handwheel and 4 diaphragm and bonnetsizes for 7 different valve sizes• Non-rising handwheel that stays at the same height during rotation,equipped with a graduated optical indicator protected by a transparentPVC cap with seal O-Ring• Bonnet fastening screws in stainless steel protected against the externalenvironment by PE plugs. Absence of metal parts exposed to the externalenvironment to prevent any risk of corrosion• New flanged bodies: the new bodies, characterised by a monolithicflanged structure, are available in PVC-U, PVC-C, PP-H and PVDF. This design,free from body and flange joints, greatly reduces mechanical stressand increases system performance.• CDSA (Circular Diaphragm Sealing Angle) system that, thanks to theuniform distribution of shutter pressure on the diaphragm seal, offers thefollowing advantages:??reduction in the tightening torque of the screws fixing the actuator tothe valve body??reduced mechanical stress on all valve components (actuator, body anddiaphragm)??easy to clean valve interior??low risk of the accumulation of deposits, contamination or damage tothe diaphragm due to crystallisation??operating torque reduction
