Automatic Drain Valve
The Inbal Automatic Drain Valve model
373-08 is designed to automatically drain
water from the fire protection system,
which must normally be maintained dry.
It is used to provide a visual indication of
leakage past the deluge valve, dry pipe
valve, or check valve; as well as to
automatically drain condensate in the
automatic sprinkler piping.
The Inbal 373-08 is also used to ensure
proper operation of the Inbal Flow
Release Pilot in case it leaks in actuated
mode to prevent Inbal Valve closure
prior to resetting. In an increase in flow
pressure, the Inbal model 373-08 will
close automatically and will reopen with
the pre-designed decrease in pressure.
