DESCRIPTION
The Trabon Spra-Control Valve automatically allows pressurized
air to enter the air-lube mixing nozzle when supplied with gear
lubricant under pressure. The Spra-Control Valve also shuts off the
pressurized-air supply to the nozzle when the lubricant pressure
ceases.
Lubricant, oil or grease, can be supplied directly from the pump,
as in the case of a single isolated spray; it can also be supplied
from a metering manifold or feeder (Trabon Type M or MX) which
feeds several Spra-Control Valves. In some cases where multi-
purpose lubricant is used, bearing taps and gear sprays may be
served by the same pump and manifold system. Air-lube nozzles
providing normal and wide cone spray patterns are of the non-
clogging external mix type. Minimum air pressure required is 20
psi, maximum is 150 psi.
FEATURES
