Features and Benefits
- In-line removable trim significantly reduces maintenance time
- Fully drainable (no hold up) when oriented for downflow with spring pressure removed and positive pressure at inlet
- No threaded connections below the diaphragm
- Minimized internal volume
- High flow rate coupled with high rangeability reduces need for reduced trim sizes
- Proprietary Jorlon diaphragm material provides exceptionally long life and CIP/SIP capability
