Diaphragm valves

  • controlled by appropriately matched pilot valves
  • integral possibility of hydraulic control, using the energy of flowing water
  • use in water supply, irrigation, fire protection systems and in industry

Needle valves

  • smooth regulation through axial movements of the piston (slider) moved by a crank mechanism
  • work even with large pressure differences and significant flows
  • they do not cause vibration and noise caused by the flow
