Introduction
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.
GENERAL:
ROSS L-O-X
®
valves are energy isolation valves and are generally
used as the first valve in a line supplying compressed air to equipment.
Air can be shut off by pushing the L-O-X
®
handle inward; downstream
air is simultaneously exhausted through the L-O-X
®
exhaust port.
Many standards & regulations, e.g., OSHA, require that the valve
be padlocked in this position to prevent handle from being pulled out
inadvertently during maintenance and/or servicing.
FEATURES:
• Easily identified by unique shape
• Corrosion-resistant 316 Stainless Steel construction
• Reliable Fluorocarbon seals withstand contaminant ingression
• Self-draining, washdown suitable design
• Trusted L-O-X
®
performance
• Lockable only in the OFF position
• Large exhaust port for rapid release of pressure
• Standard pressure sensing port with optional pressure switch or
visual indicator
• Simple push/pull of the large handle provides direct manual
operation
• Pressure sensing port allows installation of either the visual
indicator or pressure switch (see page 2) to verify pressure
downstream to the next obstruction is released.

Valve Operation
VALVE OPEN
When the 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.

VALVE CLOSED
With a push of the 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.
