The EVRM-NA/6NA series are normally open manual reset gas emergency shut-off valves that achieve mechanical closure when the solenoid coil is energized. This series connects to one or more leak detectors or alarms to detect the presence of carbon monoxide and trigger alerts. In emergencies such as gas leaks or fires, it automatically and rapidly cuts off the gas supply, offering advanced technical performance and significant energy-saving benefits. Widely used in natural gas transmission and distribution projects, gas thermal energy plants, and residential safety facilities.
