FEATURES:• Normally closed, in-line design with bubble-tight shut-off.
• Minimum 5 PSI differential required.
• High pressure: Particularly for applications where high back- pressures (up to 70 PSI) are required e.g. controlling flow spray nozzles, high pressure chemical injections, etc. Inlet pressure to 140 PSI.
• High flow rates – Cv’s from 5.2 on the 1/2" size to 80 on the 3" size.
• Unique Design: PTFE Bellows barrier-type dynamic seal prevents leaking of fugitive emissions to the atmosphere.
• Safety/Dependability: Patented Fail-Dry® safety design feature provides advance visual warning if seal malfunctions, while permitting valves to continue operating until maintenance can be scheduled.
