Valves and couplings

Coupling groove part with O-ring 

VK/B-03/20 E

Gas type
SF6 

The coupling allows to establish a connection by simply fitting both coupling parts into each other. Before load relieving of the coupling seats the pressure- and vacuum tight coupling is sealed inside with an O-ring during the coupling process. The coupling is forced to be open in coupled position. If both coupling sides are separated again the sealing seats shut oŒ automatically.
All couplings are temperature-resistant from -40 °C to +80 °C.
In special version these couplings are also available for a temperature range of -60 °C to +80 °C.
The suitable connecting parts for DILO couplings must be ordered separately.
