For corrosion resistance in wet conditions and harsh environments, these valves have a 303 stainless steel body. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

With a 316 stainless steel body for exceptional corrosion resistance, these valves are often used in wet conditions and harsh environments. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Commonly used with high-volume blowers, compressors, and air-powered conveyors, these valves quickly relieve a large amount of air in systems with a pipe size of 2 or greater. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

These valves meet ASME Code Section VIII for use with water pressure vessels.

Also known as T & P valves, these open when water temperature reaches 210° F or at the set pressure.

For use with low-pressure steam-heating boilers requiring pressure relief at 15 psi, these valves meet ASME Code Section IV.

Use these valves with liquid argon, liquid nitrogen, and liquid oxygen.

Alter the set pressure to suit your application.

Change set pressure without guesswork—the adjustment screw is marked in 25 psi increments for making pressure adjustments without a gauge.

Cleaned and bagged for oxygen service and other high-purity applications, these valves are built to withstand the extreme cold of liquid carbon dioxide, liquid nitrogen, and liquid oxygen.

A finely threaded adjustment screw lets you make precise set pressure adjustments.

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

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

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

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

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.

Valves have a brass body and NPT connections.

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

For extremely high-pressure applications in tight spots, these valves handle the same inlet pressures as other ultra-high-pressure-regulating valves within a smaller footprint.

Valves have a brass body.

Withstand inlet pressures up to 3,500 psi.

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

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.

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.

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

Body is cast iron.

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.

Designed to reduce contaminants in high-purity applications using hydrogen and methane gas, these valves have a 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.

For a longer service than cast iron valves, these have a durable bronze body and a 303 stainless steel seal.

Use these valves in pipelines.

Also known as fusible plugs, these discs have a metal core that melts at a set temperature to exhaust discharge directly.

For a longer service life than brass vacuum-regulating valves, these are made of bronze for strength and durability.

Regulate vacuum levels from your instrument panel with these valves that have threads below the adjustment handle and a panel-mount nut.

To set the pressure, unscrew the cap and turn the adjusting screw.

The pressure setting on these valves cannot be adjusted while they are installed.

Quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. Also known as quick exhaust valves.

Install these valves in the exhaust ports of air directional control valves to control exhaust air speed without needing access to your cylinder.

Prevent accidental start-up when servicing equipment.

Prevent accidental start-up when servicing equipment.

Also known as Monday-morning valves, these valves slowly introduce pressure to reduce surge damage during start-up.
