DKLDF - DIALOCK® 2-way diaphragm valve

DIALOCK® diaphragm valve with stroke limiter and male ends for socket welding, metric series
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.

Další charakteristika:

  • High visibility graduated optical position indicator protected by a transparent cap with seal O-Ring
  • Customisation plate: the customisation lets you identify the valve on the system according to specific needs
  • DIALOCK® SYSTEM: innovative handwheel with a patented immediate and ergonomic operating locking device that allows it to be adjusted and locked in over 300 positions
  • Handwheel and bonnet in high mechanical strength and chemically resistant PP-GR, providing full protection by isolating all internal metal parts from contact with external agents
  • Floating pin connection between the control screw and diaphragm to prevent concentrated loads, improve the seal and extend its lifetime
  • New design of valve body interior: substantially increased flow coefficient and reduced pressure drop. The degree of efficiency reached has also enabled the size and weight of the valve to be reduced
  • Adjustment linearity: the internal profiles of the valve also greatly improve its characteristic curve, resulting in extremely sensitive and precise adjustment along the entire stroke of the shutter
  • Valve anchoring bracket integrated in the body, with threaded metal inserts allowing simple panel or wall mounting using the PMDK mounting plate (supplied as an accessory)

  • 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
