Reduce Maintenance Costs, Improve Reliability, Increase Safety, and Lower Emissions
The Crosby J-Series with Balanced Diaphragm technology minimizes these risks by replacing the bellows with a flexible reinformed elastomer diaphragm. Diaphragms are inherently more resilient for higher backpressures and rapid pressure cycling applications. As a result, our new technology extends the backpressure limits to 80% of set pressure and increases the Kb factor up to 15%—expanding the application range of spring-loaded PRVs.
The Crosby Balanced Diaphragm Checks All the Boxes
✓ Reliability: Robust design ensures balanced operation
✓ Productivity: Extends backpressure handling while improving Kb factor
✓ Safety: 100x more resilient than metal bellows for high frequency cycling
✓ Environment Friendly: Maintains reliable protection against fugitive emissions
✓ Cost Effective: Yields long-term cost savings relative to PRVs with bellows installed
