REGO-LOKTM for Securing CGA Fittings on Liquid Cylinders

Application
The REGO-LOKTM is designed for installation on the Rego T9450 and T9460 Series liquid cylinder valves to deter and prevent the removal of the CGA fitting from the valve. The REGO-LOKTM retains standard CGA outlet connection fittings so unauthorized persons do not remove the fitting. By use of a special one-way bolt, the REGO-LOKTM is secured to the valve. The REGO-LOKTM installs in a few minutes with the use of screwdrivers. REGO-LOKTM installs without valve disassembly, brazing, welding, or drilling. The REGO-LOKTM deters and prevents fitting removal by gas customers, however allows the replacement of fittings by authorized gas supplier plant personnel.
Use REGO-LOKTM for compliance with CGA SB-26 for medical and industrial liquid cylinders.

ASME Carbon Dioxide Relief Valves

Application
The UA3149A series "pop-type" relief valves are especially designed for use as a secondary relief valve in carbon dioxide transports and stationary storage tanks. The relief valve is designed to protect the tank from excessive over pressure in the event of fire or other emergencies. A small throttling-type primary relief valve must also be provided to control boil-off and maintain tank pressure. Provisions must be made to prevent the accumulation and build-up of water and foreign material in the valve.
Features
• "Pop-type" design permits the relief valve to open slightly to relieve moderately excessive pressures.
• Relief valve "pops" open to full discharge capacity when pressure exceeds a predetermined point.
