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

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.

These valves are often used in hydraulic and lubrication systems.

With a three-port design, these valves allow inline flow from the inlet to the outlet during normal conditions and divert flow through the relief port in overpressure conditions. They are often used with feed pumps for fertilizers and bleach.

These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure.

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

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.

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

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 and NPT connections.

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

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

Withstand inlet pressures up to 3,500 psi.

Regulate pressure in air and inert gas systems from your instrument panel—these valves have threads below the adjustment knob and come with a panel-mount nut.

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.

Push-to-connect fittings form a low-pressure seal around plastic or soft metal tubing.

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

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

Body is cast iron.

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

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

Designed for oxygen service and other high-purity applications, these valves can withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen.

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.

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.

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

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