1. GENERAL INSTRUCTIONS

1.1. Scope: This safety guide is designed to cover general guidelines

on the installation, use, and maintenance of Veriflo Division valve,

pressure regulator, and flow control products and related accessories

(“products”).

1.2. Fail-Safe: Veriflo products can and do fail without warning for many

reasons. Design all systems and equipment in a fail-safe mode, so that

failure of Veriflo products will not endanger persons or property.

1.3. Relevant International Standards: For a good guide to the

application of a broad spectrum of pneumatic fluid power devices see:

ISO 4413, Hydraulic fluid power — General rules and safety requirements

for systems and their components, and ISO 4414, Pneumatic fluid

power — General rules and safety requirements for systems and their

components. Visit for ordering information.

1.4. Distribution: Provide a copy of this safety guide to each person

that is responsible for selection, installation, or use of Veriflo products.

Do not select or use Veriflo products without thoroughly reading

and understanding this safety guide as well as the specific Veriflo

publications for the products considered or selected.

1.5. User Responsibility: Due to the wide variety of operating

conditions and applications for Veriflo products, Parker and its

distributors do not represent or warrant that any particular Veriflo

product is suitable for any specific end use system. This safety guide

does not analyze all technical parameters that must be considered in

selecting a Veriflo product. The user, through its own analysis and

testing, is solely responsible for:

• Making the final selection of the appropriate Veriflo product;

• Assuring that all user’s performance, endurance, maintenance,

safety, and warning requirements are met and that the application

presents no health or safety hazards;

• Complying with all existing warning labels and / or providing all

appropriate health and safety warnings on the equipment on which

the Veriflo products are used; and

• Assuring compliance with all applicable government and industry

standards.

1.6. Safety Devices: Safety devices should not be removed or

defeated.

1.7. Warning Labels: Warning labels should not be removed, painted

over or otherwise obscured.

1.8. Additional Questions: Call the appropriate Parker technical

service department if you have any questions or require any additional

information. See the Parker publication for the product being considered

or used, or call 1-800-CPARKER, or go to /veriflo, for

telephone numbers of the appropriate technical service department and

Veriflo catalogs and publications.

2. PRODUCT SELECTION INSTRUCTIONS

2.1. Operating Pressure: The user must assure that the pressures

applied to the product will never exceed the maximum operating

pressure of the product, the maximum operating pressure of any options

and accessories connected to the product, and the maximum operating

pressure of any other system component. Consult product labeling and

Veriflo Division catalogs for maximum operating pressures. Additional

operating pressure considerations:

• Pressure regulators have an outlet operating pressure range that

is less than the maximum operating inlet pressure. Never exceed

the maximum operating inlet pressure. Never exceed the maximum

operating outlet pressure.

• Pressure gauges should be selected such that the pressure to

be measured is no more than 75% of the full-scale range of the

gauge. For additional information refer to ASME standard B40.100,

Pressure Gauges and Gauge Attachments. Visit .

org for ordering information.

• Products may be fitted with special connections and adaptors to

connect the product to a pressure cylinder. The maximum operating

pressure of the product, its options, and accessories must equal or

exceed the maximum pressure of the cylinder. For more information

regarding the selection and safe use of pressure cylinders and

cylinder connections, visit the Compressed Gas Association (CGA)

at .

Temperature rating: Never exceed the temperature ratings of a

product. Excessive heat or cold can shorten the life expectancy of a

product, cause improper function, and product rupture. Consult Veriflo

Division catalogs for maximum and minimum temperature ratings.

Leakage: Most products experience small amounts of leakage.

Product leakage must be suitable for the application, environment, and

the process fluid. Good system design and product selection require

consideration of both internal and external leakage. Leakage can create

hazardous situations due to exposure to the process fluid, unintended

chemical reactions, loss of system pressure, or unexpected transfer of

fluids and pressures within the system. Consult Veriflo Division catalogs

for product leakage rates.

Severe Leakage: The user must address in their system design and

product selection any hazards that may result from severe leakage due

to product or system failure. Good system design requires consideration

of the possibility of severe internal and external leakage and may require

safety pressure relief devices and secondary fluid containment. Severe

leakage can create hazardous situations due to exposure to the process

fluid, unintended chemical reactions, loss of system pressure, or

unexpected transfer of fluids and pressures within the system.

Flow rate: The flow rate requirements of a system are an important

consideration when selecting a product. Products need to be able to

provide adequate flow and pressure for the desired application.

Environment: Many environmental conditions can affect the

integrity and suitability of a product for a given application. Veriflo

Division products are designed for use in general purpose industrial

applications. If these products are to be used in unusual circumstances

such as direct exposure to sunlight, weather, and/or corrosive or

caustic environments, such use can shorten the useful life and lead to

premature failure of a product.

Fluid Compatibility: Veriflo products are constructed from a

variety of materials. The user is solely responsible for selecting and

2.2.

2.3.

2.4.

2.5.

2.6.

2.7.

assuring that the product and materials of construction are compatible

with the process fluid. The user must take extreme caution when

selecting products and materials for use with corrosive and hazardous

fluids. The user should contact their fluid supplier for additional safety

and product selection guidance.

2.8. Oxygen Service: Extreme caution must be taken when using

oxygen. A serious risk of ignition, fire, and explosion exists. The user is

solely responsible for selecting the product and specifying materials to

be used in oxygen service.

• Do not use a product or operate a system if there is evidence of

contamination (e.g. debris, particles, oils, lubricants, grease, etc.);

• Do not interchange products, components, or accessories with

those that have been used in other types of gas service;

• Do not operate a pressure regulator without a proper filter;

• Always apply pressure to the regulator slowly to avoid heating from

adiabatic compression. Fast opening valves should not be used.

3. PRODUCT INSTALLATION AND OPERATING INSTRUCTIONS

3.1. Product Inspection: Prior to assembly or installation a careful

examination of the product must be performed. All products must be

checked for correct style, size, and model number. DO NOT use any

product that displays any signs of nonconformance.
