Dry Evotek Couplings

DEC – Dry Evotek Couplings stands for another generation of dry disconnect couplings, that is specially made for use in the chemical industry.

The external cam curve is ergonomically designed and allows coupling against pressure in the tank unit. Rotating the coupling 120° clockwise opens the valves where the high engagement between hose and tank unit ensures a strong connection.

If the coupling halves are disconnected, their inner valves close the line securely. Once coupled, the valves open the flow cross-section with minimum pressure loss. No moving parts interfere with the flow, which makes cleaning easier. Turning the coupling counter clockwise, the valves close due to spring force. Continuing to rotate will separate the coupling halves without significant effort. 

The advantages with DEC, Dry Evotek Couplings

  • Low connecting forces even against pressure
  • Ergonomic handle (DN40 and bigger)
  • Good transmission ratio in the cam curve
  • Wide range of chemical resistance due to selection of high quality materials
  • Minimized spillage during decoupling
