Use these valves in cryogenic systems to control the flow of liquid nitrogen, carbon dioxide, and argon. They have PCTFE seats that maintain a tight seal at temperatures as low as -400° F. A vented ball relieves pressure build-up from frequent temperature fluctuations during use. These valves have an extra-long stem filled with graphite packing to prevent heat transfer and leaks. The stem is long enough to fit through thick insulation in your setup. It keeps the handle at a comfortable temperature and your hands away from hazards, so you can start and stop flow in hard-to-reach areas. Their lockable handle can be fixed in place using a padlock (not included). To maintain performance and safety, these valves are shipped cleaned and bagged to avoid contamination. All are full port, so they do not restrict flow.

Fire-tested to meet American Petroleum Institute (API) 607, these valves securely isolate flammable gases such as methane and hydrogen to prevent the spread of fire.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Designed to withstand extremely cold liquid gases, these valves are ideal for liquid nitrogen cooling systems and liquified gas storage. They have PCTFE seats that maintain a tight seal at temperatures as low as -400° F. A vented ball relieves internal gas and pressure build-up from frequent temperature fluctuations during use. These valves have an insulated, extra-long stem to prevent heat transfer and leaks. The extended stem keeps the handle at a comfortable temperature and your hands away from hazards, so you can start and stop flow even in hard-to-reach areas. To maintain performance and safety, these valves are shipped cleaned and bagged to avoid contamination.

Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection. All are full port, so they do not restrict flow. To prevent changes, add a padlock to fix the handle in place.

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. They’ll also work with liquified natural gas and liquid oxygen. They’re cleaned and bagged to meet CGA G-4.1 for oxygen service. Also known as gate valves, they open and close gradually with multiple turns of the wheel handle to prevent sudden starts and stops.

The handle raises as these valves open and lowers as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem. They have a threaded union stem housing, so you can separate the stem from the housing while the valve is inline. That means you can complete maintenance tasks, such as packing the stem, without taking apart your whole setup.

With seats that can stand up to aggressive and corrosive solutions, these valves are often used in chemical-processing applications. They bolt to flanges for adjusting and regulating flow in flanged pipelines.

Wafer valves must be sandwiched between two flanges; they have tabs or unthreaded holes to help align the valve between the flanges.

Lug valves can be sandwiched between two flanges or bolted directly to a single flange for servicing one end of the pipeline without depressurizing the other side. They have threaded flange holes with a hole pattern that matches ANSI flanges of the same pipe size.

Lockable lever handles have 10 flow-adjustment positions. The handle can be fixed in place with a padlock (not included).

Wheel handles open and close with multiple turns, providing fully adjustable flow.

To reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings. The plastic body and fluoroelastomer seal provide excellent chemical resistance. Valves open to allow flow in one direction and close when flow stops or reverses.

PVC and CPVC valves come with unthreaded socket-connect female fittings in addition to the threaded NPT female fittings.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

For a longer service life than standard valves for cryogenic liquids, these have a durable bronze body. All are cleaned and bagged for oxygen service and other high-purity applications. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves are designed to withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen. They have an internal strainer to trap debris.
