Diaphragm valve with male ends for solvent welding, metric seriesDIAPHRAGM VALVE• Connection system for solvent welding and for flanged joints• Optimised fluid dynamic design: maximum output flow rate thanks to theoptimised efficiency of the fluid dynamics that characterise the new internalgeometry of the body.• Handwheel that stays at the same height during rotation, with internalbearing to minimise friction and operating torque• Standard optical indicator• Internal operating components in metal totally isolated from the conveyedfluid• Bonnet fastening screws in STAINLESS steel protected against the externalenvironment by PE plugs• New flanged bodies: the new bodies, characterised by a monolithicflanged structure, are available in PVC-U, PVC-C, PP-H and PVDF. Thisdesign, free from body and flange joints, greatly reduces mechanical stressand increases system performance.
