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.

Commonly used in TIG welding where gas flow/coverage is a concern.

Designed for nitrogen gas purging in air conditioning, refrigeration, and plumbing systems.

For a longer service life than brass and cast iron valves, these have a durable bronze body.

Often used in wet conditions and harsh environments, these valves have a 316 stainless steel body for excellent corrosion resistance.

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.

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

Prevent changes to your pressure setting—these valves come set at a nonadjustable outlet pressure.

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

Our smallest pressure-regulating valve.

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

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.

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