Reduce contaminants in gases used in research sample systems, emission monitoring systems, chromatography, and other high-purity applications. 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.

Often used for pressure-vessel testing and other high-pressure applications, these valves can handle at least seven times the outlet pressure of standard tank-mount pressure-regulating valves.

Flowmeters let you see the gas flow rate from a distance.

Withstand inlet pressures up to 3,500 psi.

A 316 stainless steel body provides exceptional corrosion resistance in wet conditions and harsh environments.

Commonly used for oxygen service and other high-purity applications, these valves come cleaned and bagged to prevent contamination.

For easy panel mounting in your water system, these valves have threads below the adjustment knob and come with a panel-mount nut.

Withstand more than six times the inlet pressure of standard pressure-regulating valves.

Often used for oxygen service and other high-purity applications, these valves are cleaned and bagged to meet CGA G-4.1 standards to prevent contamination.

To maintain contaminant-free standards in clean room environments, these valves come cleaned and bagged to Fed. Std. Class 100 and ISO Class 5 clean room standards and have a 316 stainless steel body with a smooth finish to resist dust collection.

A cast iron body absorbs vibration from pressure changes to reduce wear and noise in your pipeline.

Thicker walls and a 304 stainless steel seal make these valves tougher than brass pressure-regulating valves.

Excellent performance at low pressures.

Hook up these valves to equipment with garden hose thread (GHT) connections.

Valves have a brass body and NPT connections.

Often used on dispensers, humidifiers, and fountains, these valves have a 316 stainless steel body that can stand up to deionized water and corrosive conditions.

For use with acetylene, hydrogen, methane, propane, or propylene gas.

Choose from valves for liquid argon, liquid nitrogen, liquid carbon dioxide, or liquid oxygen tanks.

Compression fittings bite down on hard metal and plastic tubing for a tighter seal than push-to-connect fittings.

For a longer service life than standard valves for cryogenic liquids, these have a durable bronze body. They’re for use with liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen.

A plastic body and fluoroelastomer seal stand up to harsh chemicals.

It's like getting four regulators in one—each comes with four springs so you can change between regulating pressure ranges of 2-30, 10-50, 30-90, and 100-180 psi.

Body is cast iron.

A 316 stainless steel body provides exceptional corrosion resistance in wet conditions and harsh environments.

Threads below the adjustment knob and an included panel-mount nut allow you to add these valves to your instrument panel.

Use these valves in pipelines.
