3 Inch L-O-X ® Valve for Lockout
Five good reasons to equip your pneumatic systems with
our energy isolating L-O-X ® valve:
Effectiveness: A L-O-X ® valve not only isolates the equipment
by shutting off air supply, it exhausts stored or residual air
immediately from downstream.
Ease of Use: Air shutoff is simple; just push in the bright red
handle. There’s no turning or twisting and guessing whether
the valve is completely open.
Locking protection: L-O-X ® valves are designed to allow
secure lock-out upon shutdown, using standard padlocks.
Reliability: Special Teflon seals help ensure “shift-ability”
even after long periods of non-use.
Efficiency: Large exhaust ports provide rapid exhaust of
downstream air and are threaded for silencers or remote
exhaust lines.

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.
