These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure.

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.

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

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 inlet pressures up to 3,500 psi.

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 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.

For precise control over your vacuum level, these valves have ±0.1% accuracy.

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.

For installation through thick insulation, these valves have an extra-long stem.

To withstand aggressive and corrosive solutions in miniature chemical-processing pipelines, these tiny valves have a chemical-resistant fluoroelastomer seal and a corrosion-resistant 303 stainless steel body.

The most chemical-resistant threaded valves we offer, these have a PTFE seal and an alloy body that can withstand extremely aggressive and corrosive chemicals, such as methyl ethyl ketone and toluene.

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a plastic body and a chemical-resistant seal.

Designed to withstand extremely cold liquid gases, these valves are ideal for liquid nitrogen cooling systems and liquified gas storage. Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection.

Built to handle the extreme cold of liquid gases, these bronze valves are ideal for liquid carbon dioxide carbonation systems, liquid nitrogen coolant systems, and other cryogenic applications.

Lower profile and available in smaller connection sizes than standard valves, these fit in tight spots.

Limit wear and damage in high-cycling applications—these valves have additional seals that prevent leakage to reduce maintenance time.

Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage.

Insert tubing into the fittings on these valves—no heat, solder, or flux required. With a fluoroelastomer seal and a PVDF body, they can withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. The 316 stainless steel body and seal, the PTFE seat and packing, and the Monel needle can withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Often used with portable cryogenic cylinders, these valves are a third of the height of other valves for cryogenic liquid. They are designed to withstand the extreme cold of liquid argon, liquid carbon dioxide, and liquid nitrogen. All are cleaned and bagged to meet CGA G-4.1 standards for oxygen service. These valves gradually open and close to adjust and regulate flow.

With a shorter end-to-end length than other check valves, these fit in tight spaces.

Insert tubing into the fittings—no heat, solder, or flux required.

Barbs grip onto tubing, providing a secure hold.

Insert tubing into the fittings on these valves—no heat, solder, or flux required. All are for use with water, oil, air, and inert gas. They divert flow between ports in tubing lines.

Connect these orifices to threaded pipe, or insert them into threaded holes.

Press these orifices into machined holes in connectors, manifolds, and other custom parts.

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

Designed to handle high-pressure welding applications, these CGA fittings are commonly used to connect pressure regulators to compressed gas tanks or cylinders.

Commonly used in low-pressure welding applications, these fittings connect downstream of your pressure regulator. Slide the barbed end into hose and secure with a crimp-on hose ferrule.
