A diaphragm is used to isolate media from the over seat parts of the valve, reducing media contact with the valves internal components. This is suitable for aggressive liquids or gases and helps reduce the risk of media contamination.
A latching valve is designed to allow the valve to stay either open or closed without continuous power.
Response time is application specific but as a general rule use 5ms for the E,F,G series and 10-20 ms for the A,B,C,D series.
Maximum opening pressure difference across the valve. Gems solenoid valves range from 0 to 1000 PSI
-40°F to 212°F / -40°C to 100°C Cryogenic valves are rated to -320°F / -196°C
Gems have 3 class options, each having a different maximum operating temperature. Be aware that valves left on for 5 to 10 minutes will self-heat. A typical 6 watt “A” valve will self-heat to 60°C while a 10 watt “D” valve will self-heat to 90°C
Class B 266°F / 130°C
Class F 311°F / 155°C
Class H 365°F / 180°C
