Vacuum jacketing

Vacuum jacketing

STICKS series 900 and other cryogenic valve series are available with factory-provided multi-layer absorption insulation material (MLI) and jacketing for quick installation within vacuum-insulated piping systems. All cryogenic valves can be ordered with optional factory-fitted, pre-installed housing.

The valve body is wrapped with a multi-layer absorption insulation material for high thermal quality. The stainless steel housing is welded to the standard pre-installed welding flange. The jacketed valves can be pre-configured with couplings or an open pipe for connection.

General construction and delivery features

  • Welded housing made from corrosion-resistant stainless steel
  • Housing can optionally be supplied with an polished surface treatment
  • Delivery includes leak test at the outer side of the housing
  • Preparation for connections with quick-release plug-in couplings according to customer requirement (optional)
  • Proven multi-layer absorption material for the super insulation to achieve a high thermal quality
  • Connections for vacuum pump and vacuum gauge available as additional housing features for quick-release coupling system (optional)
