CRM Series pressure regulators provide high flow and quick, positive shut off at the desired set pressure. The regulator design is a non-balanced, spring reference, pressure reducing type regulator. Designed especially for use as pressure build regulators for cryogenic liquid cylinders but suitable for many other applications.
Solid, non-tied diaphragm provides leak-free and long-lasting performance. Optimized diaphragm and adjustment spring designs provide high flow performance. All CRM Series regulators are supplied factory pre-set and 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
- Inlet Filter Screen: Protects against system debris and particulate
- 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
- Max Inlet Pressure: 600 PSIG (41.4 bar)
- Outlet Pressure Ranges:
- Spring A – 15 to 65 PSIG (1.0 to 4.5 bar) — 15 PSI/Turn
- Spring B – 50 to 175 PSIG (3.4 to 12.1 bar) — 25 PSI/Turn
- Spring C – 150 to 350 PSIG (10.3 to 24.1 bar) — 55 PSI/Turn
- Spring D – 300 to 525 PSIG (20.7 to 36.2 bar) — 70 PSI/Turn
- Temperature Range: -320° to 200°F (-196° to 93°C)
- Full Open Flow Coefficient: 0.51
- Connection: 1/4" NPT, Side IN, Side OUT
*PSI/Turn value is approximate change in setpoint per full turn of the adjustment screw (CW to increase, CCW to decrease), for reference only.
