Easy-Read Tank-Mount Pressure-Regulating
Valves with Flowmeter for Inert Gas
Flowmeters let you see the gas flow rate from a distance. These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. They have a gauge for monitoring inlet pressure from the tank.
Single-stage valves reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank. They’re best for applications where a constant outlet pressure isn’t critical.
Valves with one flowmeter are for one piece of equipment on a tank. The flowmeter has a single scale.
Adapters (sold separately) change 5/8"-18 outlets to 9/16"-18 male connections, and vice versa.
