PPH Dialock 2 Way Diaphragm Valve

PPH Dialog 2 Way Diaphragm Valve Use to control and shut off dirty or scratched substances. The redesigned internal shape of the body increases the flow coefficient and pressure drop, allowing for delicate, precise shutter adjustments over the entire stroke. The valve is quite small and lightweight. There is an ergonomic and quick locking feature on the handwheel, allowing the handwheel to be moved and secured in any position.

Many different materials, body styles and diaphragms can be used with this PPH Dialog 2 Way Diaphragm Valve. Wear-style body re-design improves flow rate and allows precise linear flow regulation throughout the valve’s full range of operation. A variety of options and accessories are available with this pneumatically operated version.

This increases the flow rate. In addition, the PPH Dialog 2 Way Diaphragm Valve allows for precise linear flow control. Through the use of its locking mechanism, the handwheel can be turned and secured in over 300 locations.

The DK DIALOCK® diaphragm valve is particularly suitable for shutting off and regulating abrasive or dirty fluids. The new internal geometry of the body increases flow coefficient, reduce pressure drop and allows a sensitive and precise adjustment along the entire stroke of the shutter. The DK is extremely compact and very light. The innovative handwheel is equipped with a patented immediate and ergonomic operating locking device that allows it to be adjusted and locked in any position.

• 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 inter-
nal 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
