BLD Series cryogenic pressure regulators provide high flow and shut off quickly at the desired set pressure. The regulator design is a non-balanced, spring reference, reducing type regulator and comes with PTFE seals for cryogenic use. These regulators are optimized for use in pressure build applications.
The solid (non-tied) metal diaphragms provide long lasting, leak-free performance. The springs for BLD Series regulators have been designed for optimized flow within the set pressure range. All BLD Series regulators are supplied cleaned for oxygen service.
- Optimized for High Flow: Design provides high flow rates at low pressure differential
- Quick Shut-Off: Regulators transition from the flowing condition to shut in a tight pressure band
- Solid, Non-Tied Diaphragm: Solid diaphragm eliminates potential leak path and increases sensitivity
- Designed for Cryogenics: All materials were selected specifically for use in cryogenic environments
- Cleaned for Oxygen Service: Regulators are cleaned for use in Oxygen service standard
- Extensively Field Qualified
