RegO Regulators

1784NG Series Gas Phase Regulators
Designed specifically for LNG vehicles for optimum performance. Highly responsive to changes in flow, pressure remains steady if flow increases. Bonnet construction features hose barb and choice of ports for dome loading. Adjusting screw is per-set and protected against tampering.

RG Series Pressure Builder Regulators
Designed to maintain the pressure in cryogenic containers, they are especially useful in installations where space and cost are important. PTFE seat enables a positive shut-off down to -196°C. Inlet filter helps prevent foreign material from entering the regulator.

ECL502 Series Economizer Back Pressure Regulators
Designed to be used as pressure reducing valves to automatically maintain a constant inlet or back pressure, normally closed at pressures below its set point and open at pressures above its set point. Provides premium flow characteristics enabling fast pressure reduction while maintaining sensitive flow control at lower pressure settings.
RegO Pressure Relief & Check Valves

9400 Series Pressure Relief Valves
Specifically designed for vapor line safety relief applications and cryogenic liquid containers. Available in brass or stainless steel.

NG900 Series Pressure Relief Valves
Designed for vapor line safety relief applications and cryogenic liquid containers. These valves open and close at preset pressures to ensure reliable performance at cryogenic temperatures to avoid over pressurization in LNG fuel tank application and LNG installation.

NG300 Series In Line Check Valves
For use with LNG liquid lines as an effective shut-off utilizing ball and spring mechanism. ⅛” design fits compact piping systems. Heavy-duty spring and precision ball provide dependable service. Available in brass or stainless steel.
RegO Shut-off & Excess Flow Valves

T9450 Series Shut-off Valves
Designed for use on portable cryogenic cylinders, LNG fueling systems and other in-line shut-off valve applications. Spring-loaded stem seal automatically adjusts for any gasket wear, eliminating the need to constantly re-tighten the packing nut.

T9460 Series Shut-off Valves
Designed for use on portable cryogenic cylinders, LNG fueling systems and other in-line shut-off valve applications. Spring-loaded stem seal automatically adjusts for any gasket wear, eliminating the need to constantly re-tighten the packing nut.

NG304 Series Excess Flow Valves
For use with LNG liquid lines as an effective shut-off when an excess flow condition occurs downstream to prevent uncontrolled release of system media. Poppet design provides high-flow capacity. Design allows spring to reset poppet automatically when system pressure equalizes.

SSV9400 Series Solenoid Valves
RegO Filling & Venting Components

MFR100 Series LNG Receptacles
Provides a safe and secure connection with the CryoMac®3 50M LNG Nozzle and other LNG Nozzles. Flow capacity 50 GPM. Available in most standard inlet connections, different outlet available upon request.

MRF5000 Filler Caps
Textured grip makes for easy on and off. Snug fit keeps debris out of filling receptacle. Sturdy wire lanyard keeps it close at hand.

MDQ100 Series Quick Disconnect Vents
For venting excess pressure in LNG vehicle tanks. Engineered for easy connection / disconnection with quick disconnect vent couplers. PTFE seat provides positive shut off at cryogenic temperatures.
