    High-Purity Tank-Mount Pressure-Regulating Valves for Inert Gas

    Reduce contaminants in research sample systems, emission monitoring systems, chromatography, and other high-purity applications that use argon, helium, nitrogen, or carbon dioxide. These valves have a 316 stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination. They 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. Outlet fittings are Swagelok® for a leak-free seal around hard metal tubing in high-pressure lines. Also known as instrumentation fittings, Swagelok® fittings are compatible with Parker A-Lok, Gyrolok, Bilok, and Tylok fittings. Valves have a gauge to monitor outlet pressure and a gauge to monitor inlet pressure from the tank.
    Choose a valve with a maximum outlet pressure that’s approximately twice your application’s normal operating pressure. Your operating pressure should never exceed 75% of the valve’s maximum outlet pressure.

    Chrome-Plated Brass Body—Chrome-plated valves add a layer of corrosion resistance.
    Single Stage—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.
    Two Stage—Two-stage valves progressively reduce pressure over two steps for more consistent outlet pressure at all times. They’re often used in applications that require a constant outlet pressure regardless of the tank level.

    Cleaned and Bagged Panel-Mount Pressure-Regulating Valves for Air and Inert Gas

    Image of Product. Front orientation. Pressure-Regulating Valves. Cleaned and Bagged Panel-Mount Pressure-Regulating Valves for Air and Inert Gas.
    Commonly used for oxygen service and other high-purity applications, these valves come cleaned and bagged to prevent contamination. All automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have threads below the adjustment knob and come with a panel-mount nut. They can also be surface mounted. All have two gauge ports. Body is 316 stainless steel for exceptional corrosion resistance. Valves are no-bleed style, so they keep process gases contained in the valve.
