- Cost-effective for high-volume integration
Series Performance Comparison
| Specification | R-900 (Relieving) | R-910 (Non-Relieving) | R-920 (Near-Zero Bleed) |
|---|---|---|---|
| Regulator Type | Constant Bleed | Non-Bleed | Near-Zero Bleed |
| Repeatability | < ± 0.1 PSI | < ± 0.25 PSI | < ± 0.25 PSI |
| Supply Variation | < 0.07 PSI per 10 PSI | < 0.1 PSI per 5 PSI | < 0.1 PSI per 5 PSI |
| Max Flow | 2.3 CFM (65 LPM) | 2.3 CFM (65 LPM) | 2.3 CFM (65 LPM) |
Note: R-910 is not recommended for dead-end applications. R-920 relieves only what is necessary to stabilize the pressure setting.
