Pneumatic Actuators for Internal & Emergency Shut-off Valves
Field Topics are intended to provide useful information to the network of authorized LP-Gas and Anhydrous Ammonia distributors regarding the proper use of RegO® products.
Warning Bulletins covering many of the hazards involved are available from RegO for more detailed information. These bulletins can be found in our L-500, L-102 and NH3-102 catalogs. Neither the Field Topic or the Warning Bulletins are intended to conflict with federal, state, or local ordinances and/or regulations, which should be observed at all times. This information also is not intended to be a substitute for or to supplement any training in the safe handling and use of propane and related equipment, as required by any applicable law. By providing this material, ECI assumes no responsibility for providing any such training. Only individuals properly trained in the safe handling and use of propane and related equipment should be permitted to do so, and by providing this information, ECI does not assume responsibility for providing such training
For more information on LP Gas system requirements, refer to Liquefied Petroleum Gas Code (NFPA 58), National Fuel Gas Code (NFPA 54), National Propane Gas Association Safety Handbook, the RegO LP-Gas Serviceman’s Manual L-545, RegO catalogs L-500/L-102/NH3-102, ANSI K61.1 Safety Requirements for Storage and Handling of Anhydrous Ammonia, as well as any applicable local codes and ordinances.
During the selection process of a RegO internal valve and/or Emergency shut-off valve actuators must be ordered separately for pneumatic, cable or electric systems.
It is important to order each regulator with the proper vent position specified. This will ensure the user Pneumatic actuators can be operated using a source of nitrogen, compressed air or propane vapor. When using propane vapor as a source, it is important to install so there is no result of condensation of the LP-Gas vapor. Additionally, if you are experiencing low temperatures and conditions, the vapor pressure in the container must meet the minimum operating pressure of the pneumatic actuator. When using compressed air as a source it is important to install with a means to prevent excessive moisture. Excessive moisture in a pneumatic system could cause freezing and corrosion which could, in turn, prevent the proper operation of the actuator.
To properly install a pneumatic system, it is important to be aware of the minimum and maximum operating pressures of each actuator in the system. The chart below is to help as a guide to selecting the proper pneumatic actuator and supply pressure needed for your system.
