Series 15 Manual L-O-X ® Valves
• Reliable, Low-Cost Control
• 1 1/2 and 2 Ports
VALVE CLOSED
With a short push of the red
handle inward, the flow of supply
air is blocked and downstream air
is exhausted via the exhaust port
while servicing or maintaining
machinery. Padlock the L-O-X
®
valve in this position to prevent
the handle from being pulled
outward inadvertently to avoid
potential for human injury while
servicing machinery.
VALVE OPEN
When the red handle is pulled
out, supply air flows freely from
inlet to outlet and flow to exhaust
is blocked. A detent keeps the
handle in the open position. The
handle is not designed to be
locked in this position, thereby
providing for ready shut-off when
necessary.
The ROSS LOX ® 1-1/2 and 2 inch port size are the newest addition to
ROSS’ renowned family of safety-related products. Following any FRL
components, an energy isolation valve is usually the first valve in the line
supplying compressed air to equipment. The energy isolation valve should
provide a quick means of shutting off the supply of air and exhausting
the downstream lines.
The ROSS manual L-O-X
® valve has a large red operating handle for high
visibility. When the handle is pulled out, there is full line pressure. A short,
full inward push of the handle closes off the flow of air, and quickly exhausts
the pressure in the downstream line. This action is swift and doesn’t require
a difficult, slow, or confusing twisting action.
NOTE: If a system requires gradual buildup of downstream pressure, see
L-O-X
® valves with EEZ-ON ® operation on page 4.
The controlling spool of the valve employs seals made of very low-friction
material. These seals enable the L-O-X
® spool to shift smoothly and easily
even after being on standby for a long period of time.
The exhaust port is threaded for the installation of a silencer or a line
for remote exhausting. Two mounting holes are provided to simplify the
installation of the L-O-X
® valve.
Manual L-O-X ® valve shown padlocked in
closed position. The valve can only be
locked in the closed position.
Push/pull operation - Push the handle inward
to exhaust downstream air (lockable in this
position). Pull the handle outward in to
supply air downstream.

NOTE: Per specifications and regulations, these products are
defined as energy isolation devices,
NOT AS EMERGENCY STOP
DEVICES.
L-O-X ® Sensing Port
L-O-X ® Sensing Port - Series 15 manual L-O-X ® valves and manual L-O-X ® valves with EEZ-ON ® operation are now provided with 1/8
NPT sensing ports, enabling installation of a pressure sensing device such as the Pop-Up Indicator or Pressure Switch shown below.
Standards suggest that machine design should include a method for verifying the release of energy after lockout.
The ROSS 988A30 Pop-Up Indicator is constructed for the industrial environment with a brass body and 1/8” NPT connection. It offers
360° visibility and a redundant verification feature. By pushing on the red plunger, the operator can “feel” the presence of pressure
and verify that the indicator is performing its sensing function.
The ROSS 586A86 Pressure Switch offers an electronic pressure sensing option that can be integrated into a safety monitoring system,
which confirms energy isolation throughout the circuit.
NOTE: Model number 5500B9001 is female threaded as is the exhaust port in the valve. Therefore, a pipe nipple will be needed in
order to attach the muffler to the valve.
CAUTION: These L-O-X
® valves are rated to 20 bar (300 psig), but the mufflers listed above are rated only to 10 bar (150 psig). These
mufflers must not be used for applications with pressures greater than 10 bar (150 psig) or serious injury or damage could occur.
