Ross L-O-X 15 Series Manual

15
Series
Thank You!
You have purchased a premium-quality ROSS
It is a high quality energy isolation valve for international standards
compliance designed for in-line mounting. With care in its installation
and maintenance you can expect it to have a long and economical
service life.
Before you install this valve read the information in this folder
completely, and save it for future reference.
Please read and make sure you understand all installation instructions before proceeding with the installation.
Additional technical documentation is available for download at www.rosscontrols.com.
If you have any questions about installation or servicing your valve, please contact ROSS or your authorized ROSS distributor,
see contact information listed at the back of this document, or visit www.rosscontrols.com to find your distributor.
IMPORTANT NOTE: Per specifications and regulations,
these valves are defined as energy isolation devices, NOT
AS EMERGENCY STOP DEVICES.
Pneumatic equipment should be installed only by persons
trained and experienced in such installation.
A L-O-X ® valves or L-O-X

EEZ-ON Operation Valve

NOTE: The L-O-X valves and the L-O-X
®
operation are similar in appearance, but different in that the L-O-X
valve has a red handle, and the L-O-X
operation has a blue handle. The operating functions of the two
types of valve differ in the following ways:
L-O-X Valve: Pushing the RED handle inward cuts off the
®
supply of air to downstream components, and at the same time
exhausts the air in the downstream lines to the next obstruction.
The L-O-X valve is NOT an emergency stop device, but simply
®
an energy isolation device. When the red operating handle
is pulled outward, supply air is again allowed to flow into the
downstream lines.
L-O-X valve with EEZ-ON
®
operating handle is pushed inward this valve functions like the
L-O-X valve described above. In addition, when the blue handle is
®
pulled outward, the flow of air to the downstream lines is gradual.
When outlet pressure reaches approximately 25 psi (1.7 bar)
less than inlet pressure, the valve will then open fully until the
upstream pressure is exhausted or the handle is pushed down.
Air Lines: Before installing this valve in a new or existing system,
the air lines must be blown clean of all contaminants.
It is recommended that an air filter be installed in the inlet line
close to the valve.

Modular
Valve Inlet (Port 1): Be sure that the supply line is of adequate
size and does not restrict the air supply.
Valve Outlet (Port 2): For quick pressurizing and exhausting
of downstream components, the downstream lines must be of
adequate size and be free of crimps and sharp bends.
Valve Exhaust (Port 3): Do not restrict the air flow from the
exhaust port as this can adversely affect the speed with which
downstream lines and components can be exhausted. To reduce
exhaust noise, an efficient silencer may be used. ROSS silencers
reduce impact noise by as much as 25 dB, and produce little
back pressure.

L-O-X Sensing Port: A 1/8 NPT sensing port allows installation
®
®
of either the Pop-Up Indicator (model number 988A30) or
Pressure Switch option (model number 586A86) to verify
pressure is released.
Operating Pressures and Temperatures: Allowable ranges for
pressure and temperatures are given in the Valve Specifications
on page 2. Exceeding these values can shorten valve life.
Pipe Installation: To install pipe in valve ports, engage pipe
one turn, apply pipe thread sealant (tape not recommended), and
tighten pipe. This procedure will prevent sealant from entering
and contaminating the valve.
EEZ-ON Adjustment: If using a L-O-X
®
operation (valve with a blue handle), push the handle fully inward
before applying line pressure to the inlet port. Turn the brass
adjusting screw in the top of the blue handle clockwise until
resistance is felt. DO NOT TIGHTEN OR THE SCREW MAY
BE DAMAGED. Now turn the adjusting screw counterclockwise
1/2 turn. This will serve as a preliminary setting for the rate of
pressure buildup. Further adjustment can then be made to suit
the needs of your application.
