Product Description:
A4020 series universal valve leakage self-inspection system is designed and developed on the basis of microprocessor.
It opens or closes the electric valve in a certain logical way, and determines whether the valve is leaking by detecting the pressure difference.
It can be used with Honeywell's 7800 series, Satronic series and other companies' combustion safety controllers to automatically check double valves or valve groups.
During the automatic detection process, once a valve leak is found, the start of the combustion process will be interrupted and an alarm will be issued.
To ensure the safe operation of combustion equipment.
