Installation Safety Guidelines For Selecting And Using
ROSS CONTROLS Products And Related Accessories
WARNING:
FAILURE OR IMPROPER SELECTION OR IMPROPER USE OF ROSS CONTROLS PRODUCTS, ASSEMBLIES OR RELATED
ITEMS (“PRODUCTS”) CAN CAUSE DEATH, PERSONAL INJURY, AND/OR PROPERTY DAMAGE. POSSIBLE CONSEQUENCES
OF FAILURE OR IMPROPER SELECTION OR IMPROPER USE OF THESE PRODUCTS INCLUDE BUT ARE NOT LIMITED TO:
• Unintended or mistimed cycling or motion of machine members or failure to cycle
• Work pieces or component parts being thrown off at high speeds.
• Failure of a device to function properly for example, failure to clamp or unclamp an associated item or device.
• Explosion
• Suddenly moving or falling objects.
• Release of toxic or otherwise injurious liquids or gasses.
Before selecting or using any of these Products, it is important that you read and follow the instructions below.
1. GENERAL INSTRUCTIONS
1.1. Scope: This safety guide is designed to cover general guidelines on the installation, use, and maintenance of ROSS CONTROLS Valves,
FRLs (Filters, Pressure Regulators, and Lubricators), and related accessory components.
1.2. Fail-Safe: Valves, FRLs, and their related components can and do fail without warning for many reasons. Design all systems and
equipment in a fail-safe mode, so that failure of associated valves, FRLs or related accessory components 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 4414:1998, Pneumatic Fluid Power – General Rules Relating to Systems. See www.iso.org 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 Valves or FRL
products. Do not select, or use ROSS CONTROLS valves or FRLs without thoroughly reading and understanding this safety guide as
well as the specific ROSS CONTROLS publications for the products considered or selected.
1.5. User Responsibility: Due to the wide variety of operating conditions and applications for valves and FRLs ROSS CONTROLS and its
distributors do not represent or warrant that any particular valve or FRL is suitable for any specific end use system. This safety guide does
not analyze all technical parameters that must be considered in selecting a product. The user, through its own analysis and testing, is
solely responsible for:
• Making the final selection of the appropriate valve, FRL or accessory.
• 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
valves or FRLs are used; and,
• Assuring compliance with all applicable government and industry standards.
1.6. Safety Devices: Safety devices must not be removed, defeated or designed around.
1.7. Warning Labels: Warning labels must not be removed, painted over or otherwise obscured.
1.8. Intake / Exhaust Restriction: Do not restrict the air flow in the supply line. To do so could reduce the pressure of the supply air
below the minimum requirements for the valve and thereby cause erratic action. Do not restrict a poppet valve’s exhaust port as this
can adversely affect its operation. Exhaust silencers must be resistant to clogging and have flow capacities at least as great as the
exhaust capacities of the valves. Contamination of the silencer can result in reduced flow and increased back pressure.
1.9. Mechanical power presses and other potentially hazardous machinery using a pneumatically controlled clutch and brake mechanism
must use a press control double valve with a monitoring device. A double valve without a self-contained monitoring device should be
used only in conjunction with a control system which assures monitoring of the valve. All double valve installations involving hazardous
applications should incorporate a monitoring system which inhibits further operation of the valve and machine in the event of a failure
within the valve mechanism.
1.10. Additional Questions: Call the appropriate ROSS CONTROLS technical service department if you have any questions or require any
additional information. See the ROSS CONTROLS publications for the product being considered or used, or call your local distributor or
ROSS CONTROLS' Technical Service department at 1-888-TEK-ROSS in the U.S.A. (1-706-356-3708 outside the U.S.A.). You may find
your local ROSS distributor at www.rosscontrols.com.
2. PRODUCT SELECTION INSTRUCTIONS
2.1. Flow Rate: The flow rate requirements of a system are frequently the primary consideration when designing any pneumatic system.
System components need to be able to provide adequate flow and pressure for the desired application.
2.2. Pressure Rating: Never exceed the rated pressure of a product. Consult product labeling, ROSS CONTROLS catalogs or the
instruction sheets supplied for maximum pressure ratings.
2.3. Temperature Rating: Never exceed the temperature rating of a product. Excessive heat can shorten the life expectancy of a product and
result in complete product failure.
