CONCOA 677 Series Switchover | Pressure Differential Switchover | 3000 PSIG Inlet, 316L Stainless
Part Number : CONCOA-677-SERIES-SWITCHOVER
The CONCOA 677 Series is a pressure differential switchover that keeps high purity gas flowing continuously at high flow rates with relatively low static. It suits non-corrosive high purity gases such as nitrogen, argon, helium, hydrogen, methane, oxygen and their mixtures, while EPDM seats cover carbon dioxide, nitrous oxide and certain hydrocarbons that standard FKM seats cannot handle. The series is configured to order: FKM or EPDM seats, open inlet ports or inlet shut-off valves, inlet purge valves, and an integral line regulator are all chosen when ordering. Without the line regulator, constant outlet pressure needs a regulator fitted downstream.
Key features
- Priority valve changes cylinder priority with no interruption in gas flow
- 316L stainless steel regulator bodies, bonnets and 40-micron filters
- Altos 2™ alarm integration gives advance notice of switchover
- Optional outlet valve for pipeline isolation and optional 4-20 mA transducers
- 3000 PSIG (210 BAR) maximum inlet, Cv 2.3, weight 37 lbs (16.8 kg)
