Honeywell Solenoid valves for hot water, steam, up to 120 degree LG-series Socket connection L15G31M

Fema piston-type solenoid valves of the LG series are particularly suitable for use as stop and safety check valves in heating installations

up to 120°C or 180°C.

The coupled (automatically servo-controlled) mode of operation does not require a minimum differential pressure; the units open and close

without difficulty even without pressure or with low differential pressures.
