The application
Build around the experiment.
Research installations often combine tight space constraints, repeated cool-down cycles and specific flow or leakage requirements. A clear valve schedule helps separate isolation, control and measurement duties. The selection below focuses on products with published liquid-nitrogen service.
Insulated cold lines
Vacuum-jacketed globe, shut-off and lift-check configurations for LN2 pipework.
Measurement & auxiliaries
Liquid-level manifolds, compact globe valves and strainers for instrument and process lines.
Selection essentials
What defines the right configuration?
- Experiment
- Medium, fluid state, flow range, temperature and pressure.
- Performance
- Leakage criteria, modulation, cycle frequency and repeatability.
- Interfaces
- Connection geometry, envelope, insulation and instrument access.
- Evidence
- Material records, test procedure and acceptance criteria.
