VK/B-03/20 E Coupling groove DN20 with metric thread

Product catalog summary

Overview: The document describes the specifications and features of the DN20 coupling, model VK/B-03/20 E, which is designed for establishing connections through a simple fitting process. It includes details on its construction, operational temperature range, and optional accessories.

Specifications: The coupling features a groove with a metric thread and is sealed with an O-ring during the coupling process to ensure pressure and vacuum tightness. It is made from stainless steel according to DIN EN 1.4305 standards and is suitable for use with SF6 gas. The nominal pressure is specified in bar, and the nominal width is DN20.

Temperature Resistance: Standard couplings are resistant to temperatures ranging from -40 °C to +80 °C. Special versions are available for a broader range of -60 °C to +80 °C.

Operational Features: The coupling is designed to remain open when coupled and automatically seals when uncoupled. It requires separate ordering of suitable connecting parts for DILO couplings.

Optional Accessories: The document lists optional accessories including a spare O-ring (05-0057-R039), a coupling tongue part (VK/F-02/20 E), and a covering cap for the coupling groove part DN20 (VK/KN-04/20 E).

Additional Notes: The actual product may differ slightly from the image provided in the document.

Catalog excerpts

VK/B-03/20 E Coupling groove DN20 with metric thread-1

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 0-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 o 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. Technical data
