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

DIALOCK® diaphragm valve with female union ends for solvent 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.

• 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
