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)
