Series 15 L-O-X ® Valves with EEZ-ON ® Operation
Combines L-O-X ® Shut-off with EEZ-ON ® Gradual Starts
VALVE CLOSED
With a short push of the blue handle
inward, the flow of supply is blocked
and downstream air is exhausted via
the exhaust port at the bottom of the
valve. It is required by OSHA that the
L-O-X
® valve with EEZ-ON ® operation
be padlocked in this position to prevent
the handle from being pulled outward
inadvertently when potential for human
injury exists or servicing machinery.
VALVE OPEN
After the blue handle is pulled out and
pressure downstream has gradually
increased, the valve automatically
changes to a fully open state, allowing
full flow from inlet to downstream.
See “Toggle Open Pressure” under
standard specifications.
Combining two functions critical to safety concerns in any application,
the ROSS L-O-X
® valve with EEZ-ON ® operation provides the shutdown
and the gradual start-up (or, “soft start”) capabilities today’s systems
require. In addition, because the L-O-X
® valve with EEZ-ON ® operation
is two units in one, you eliminate the need for multiple components. And
that means easier installation and less cost.
The valve permits the gradual increase of downstream pressure in
the pneumatic circuit that has just been actuated. The same unit
also features a shut-off and lockout of system air to limit inadvertent
actuation. For years, ROSS products have been the industry benchmark
in safety-related pneumatic controls, and the tradition continues with the
L-O-X
® valve with EEZ-ON ® operation.
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 with EEZ-ON ® operation.

The L-O-X® with EEZ-ON® operation valve combines shut-off certainty with
gradual pressurization upon start-up. Special labels and adjustment screw
indicates EEZ-ON
® function.
EEZ-ON ® VALVE FUNCTION
With the blue handle pulled out, the
adjustable needle valve (accessed
through top of handle) setting determines
the rate of pressure buildup.

L-O-X ® Sensing Port
L-O-X ® Sensing Port - Series 15 manual L-O-X ® 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.
