For a longer service life than brass and cast iron valves, these have a durable bronze body.
A cast iron body absorbs vibration from pressure changes to reduce wear and noise in your pipeline.
These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure.
Often used in wet conditions and harsh environments, these valves have a 316 stainless steel body for excellent corrosion resistance.
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.
Prevent changes to your pressure setting—these valves come set at a nonadjustable outlet pressure.
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.
Rated for more than double the temperature of standard pressure-regulating valves, these can withstand temperatures up to 550° F.
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.
A 316 stainless steel body provides exceptional corrosion resistance in wet conditions and harsh environments.
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.
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.
These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure.
Flowmeters let you see the gas flow rate from a distance.
Commonly used in TIG welding where gas flow/coverage is a concern.
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.
Designed for nitrogen gas purging in air conditioning, refrigeration, and plumbing systems.
Choose from valves for liquid argon, liquid nitrogen, liquid carbon dioxide, or liquid oxygen tanks.
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 use with acetylene, hydrogen, methane, propane, or propylene gas.
Install these valves directly in gas distribution pipelines.
Use these valves in pipelines.
Threads below the adjustment knob and an included panel-mount nut allow you to add these valves to your instrument panel.
Our only valves that meet ASME Code Section VIII for use with cryogenic pressure vessels. They are for use with argon, carbon dioxide, helium, hydrogen, methane, nitrogen, and oxygen.
Change set pressure to suit your application—this valve includes four interchangeable color-coded springs with different set pressure ranges.
Body is brass or nickel-plated brass. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.
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.
The most basic option for air and inert gas applications.
These valves have a bronze body for durability and a long service life. 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.

Design a valve specifically for your process media and set pressure. Choose from a valve for air, inert gas, water, hydraulic oil, fuel oil, gasoline, or diesel fuel and a set pressure.
A finely threaded adjustment screw lets you make precise set pressure adjustments.
To gradually relieve pressure in lines for diesel fuel, fuel oil, gasoline, and kerosene, these valves begin opening at the set pressure and fully open at about 10% over the set pressure.
For precise control over your vacuum level, these valves have ±0.1% accuracy.
A lighter and more corrosion-resistant alternative to metal vacuum-regulating valves.
For a longer service life than brass vacuum-regulating valves, these are made of bronze for strength and durability.
These valves have a brass body.
A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals.
Rated for 12 times the pressure of standard vacuum-breaking valves, these can handle up to 1,500 psi. Connections are NPT.
Commonly used with irrigation systems and laboratory equipment, these valves have NPT connections.
