Pneumatic / Electric
Lube Sentry Valve
The Lube Sentry Valve provides automatic warning and
shutdown of compressors, pumps and engines when oil is
not flowing properly to primary dividers in series type lube
systems.

PNEUMATIC LUBE SENTRY VALVE
Pneumatic shutdown can be achieved with the Pneumatic Lube
Sentry which meets all hazardous condition area requirements.

ELECTRIC LUBE SENTRY VALVE
For electric shutdown of machinery, the Electric Lube Sentry is
available.

DESCRIPTION
The Lube Sentry is a simple, compact unit that installs in the
main lube line between the lube pump and master divider, and
downstream from any meters or filters (recommended) between the
pump and the divider.

It consists of two separate units - an actuator and a 3-way
pneumatic valve on the Pneumatic Lube Sentry, and an actuator
and microswitch assembly on the Electric Lube Sentry - that are
bolted together. It’s designed for use in series type systems with
flow rates ranging from 4 to 400 pints of oil per day at pressures
up to 6,000 psi (414 bar).
The Pneumatic Lube Sentry can also be used to control pilot
pressure to compatible air safety shutdown valves on gas
compressor engines.

FEATURES / BENEFITS
The Pneumatic and Electric Lube Sentry also feature:
•t Absence of check valves to avoid trapping contamination
from included solids in the lubricant.
•t

B
olted-together components simplifying maintenance.
The microswitch assembly on the pneumatic valve can be
removed without disturbing existing lines or shutting down
the equipment being lubricated.
