WARNING:
FAILURE OR IMPROPER SELECTION OR IMPROPER USE OF THIS PRODUCT
CAN CAUSE DEATH, PERSONAL INJURY AND PROPERTY DAMAGE.
This document and other information from the Verio Division of Parker Hannin Corporation,
its subsidiaries and authorized distributors provides product and/or system options for further
investigation by users having technical expertise. It is important that you analyze all aspects of
your application, including consequences of any failure and review the information concerning
the product or system in the current product catalog. Due to the variety of operating conditions
and applications for these products and systems, the user, through its own analysis and testing,
is solely responsible for making the nal selection of the products and systems and assuring that
all performance, safety and warning requirements of the application are met.
The products described herein, including without limitation, product features, specications,

OXYGEN SERVICE
The user is solely responsible for selecting the valve and specifying materials to be used
in oxygen service. Extreme caution must be taken when using oxygen. A serious risk of
ignition, re, and explosion exists
• Do not use a valve or operate a system if there is evidence of contamination (e.g. debris,
particles, oils, lubricants, grease, etc.);
• Do not interchange valves, components, or accessories with those that have been used in
other types of gas service;
• Always open a valve slowly to avoid heating from adiabatic compression.
Fast opening valves should not be used.
!WARNING:
• Users must be trained and equipped for the handling, use and servicing of high-pressure uids
and systems.
• Users must contact their gas or liquid supplier for specic safety precautions and instructions.
• Always wear appropriate protective clothing including approved safety glasses, gloves,
aprons, etc.
• Follow all applicable safety and maintenance procedures.
• Obey local, government and agency codes and regulations.
• Do not exceed the maximum inlet and outlet pressures of the product.
• Do not exceed the maximum operating pressure of pressure gauges, connections or other
accessories provided with the product. Note that the maximum operating pressure of an
accessory may be less than or greater than the maximum inlet pressure marked on the
product.
• Operate within the temperature limits and other conditions specied for the product.
• Venting uids and gases can be dangerous. Vent to a safe environment, away from
employees. Ensure adequate ventilation to prevent suocation.
• Questions regarding the installation, operation, and maintenance of a Verio product should
be directed to (510) 235-9590 in the U.S. or visit our web site.
SAFETY PRECAUTIONS
!
Verio oers a variety of diaphragm valves with various inlet connections,
outlet connections, and actuators and other options. Before installing the
valve you should fully understand the options of your particular valve and its
suitability for the application.
Step 1 Verify that the valve is rated for the system operating pressures and has the
proper connections and options for the type of gas and pressures required for
your application.
Step 2 Inspect the valve and your system connections for evidence of contamination
or damage. Valves that are damaged or contaminated should not be used.
Step 3 The uid supplied to the valve must be clean. Contamination can damage the
valve’s seat and cause a leak.
Step 4 Inlet and outlet connections may be identied by an arrow marked on the
body for 2 port valves or by “IN” and “OUT” marking on multiple port valves.
Step 5 Securely tighten connection ttings in accordance with procedures
recommended by the tting manufacturer or appropriate industry standards.
Step 6 Perform leak tests to verify there are no leaks to atmosphere or across the
valve seat. Leak test methods should be appropriate for the system leak
integrity requirements.
Step 7 Follow all applicable safety and maintenance procedures for your system
before applying system pressure.
Step 8 The valve is now ready for operation.
Installation
Operation
Manual Valves
• To open the valve: Turn the handle counterclockwise until the stop is reached.
• To close the valve: Turn the handle clockwise until the valve is fully closed.
Toggle Valves
• To open the valve: Place the lever in the vertical position.
• To close the valve: Place the lever in the horizontal position.
Air Operated Valves, Normally Closed
• To open the valve: Apply 70 - 100 psig to the actuator port.
• To close the valve: Vent the pressure to the actuator to 0 psig.
Air Operated Valves, Normally Open
• To open the valve: Vent the pressure to the actuator to 0 psig.
• To close the valve: Apply 70 - 100 psig to the actuator port.
Operation (continued)
Maintenance
Verio valves are packless and do not require packing adjustment. Do not loosen
or remove the clamp nut. A valve should be checked periodically for proper and
safe operation. A valve should also be checked after cylinder changes or system
maintenance. The user is solely responsible for determining the frequency of
maintenance based on the application, that the recommended checks can be safely
performed, and that the recommended checks are adequate to ensure proper and safe
operation of the user’s system. A valve that does not comply with the recommended
checks or malfunctions in any manner must be immediately removed from the service.
Do not attempt to repair the valve.
• Check for valve seat leak. With the valve closed, there should be no leak across
the valve seat. Leak test methods should be appropriate for the system leak
integrity requirements.
• Check for leaks to atmosphere. With the valve open, there should be no leaks
to atmosphere. Leak test methods should be appropriate for the system leak
integrity requirements.
Removing a valve from service: Follow your system safety and maintenance
procedures when removing a valve from service. Before removing a valve, the user
must:
• Isolate the valve from all pressure sources upstream and downstream of the
valve by closing the appropriate valves.
• Lockout valves and other system equipment needed to isolate pressure sources.
• Properly purge hazardous gases from the valve.
• Vent all pressure in the valve. The valve should be open to ensure pressure is not
trapped in the valve.
