Manual operation: Lift stem to drain bowl
Automatic drain connection: Will fit 1/8-27 and 1/8-28 pipe thread - Flexible tube
with 3/16" (5mm) minimum I.D. can be connected to the automatic drain. Drain
may fail to operate if the tube I.D. is less than 3/16" (5mm). Avoid restrictions in
the tube.
Automatic drain operating conditions (float operated):
Bowl pressure required to close drain: Greater than 5 psig (0.3 bar)
Bowl pressure required to open drain: Less than 3 psig (0.2 bar)
Minimum air flow required to close drain: 0.2 scfm (0.1 dm

An automatic drain is a two-way valve, which will close when the system is
pressurized. The drain opens when the float rises due to accumulated liquid
and on depressurization.
