FIP Italy DKDF Series DN 15÷65 DIALOCK® 2-way Diaphragm Valve

DIALOCK® diaphragm valve with male ends for socket welding, metric series

DIALOCK® 2-WAY DIAPHRAGM VALVE

• Connection system for solvent weld, threaded and flanged joints

• Optimised fluid dynamic design: maximum output flow rate thanks to

the optimised efficiency of the fluid dynamics that characterise the new

internal geometry of the body

• Internal components in metal, totally isolated from the fluid and external

environment

• Modularity of the range: only 2 handwheel and 4 diaphragm and bonnet

sizes 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 transparent

PVC cap with seal O-Ring

• Bonnet fastening screws in stainless steel protected against the external

environment by PE plugs. Absence of metal parts exposed to the external

environment to prevent any risk of corrosion

• New flanged bodies: the new bodies, characterised by a monolithic

flanged structure, are available in PVC-U, PVC-C, PP-H and PVDF. This design,

free from body and flange joints, greatly reduces mechanical stress

and increases system performance.

• CDSA (Circular Diaphragm Sealing Angle) system that, thanks to the

uniform distribution of shutter pressure on the diaphragm seal, offers the

following advantages:

??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
