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.

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

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

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.

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.

Excellent performance at low pressures.

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.

Use this valve in light duty water systems with garden hose thread (GHT) connections.

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

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

Change outlet pressure without using a gauge—turn the dial to adjust the outlet pressure in 5 or 10 psi increments.

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.

Rated for more than double the temperature of standard pressure-regulating valves, these can withstand temperatures up to 550° F.

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

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

Valves have NPT connections.

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.

Regulate air, gas, and liquid pressure on food, beverage, and pharmaceutical lines with these valves—they’re 3-A certified to meet sanitary design standards.

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

These valves meet NSF/ANSI 61 for use in drinking water systems.

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

These valves have a cast iron body.
