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.

Fire-tested to meet American Petroleum Institute (API) 607, these valves securely isolate flammable substances 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.
