![](/prerenderstable/mvPRE/contents/gfx/imagecache/371/3710k33p1-c03a-digital@halfx_637043688557577912.png?ver=imagenotfound)
- Valve Type: Ball
- For Use With: Diesel Fuel, Fuel Oil, Gasoline
- Seal Material: PTFE Plastic
These valves have 37° flared tube fittings that form a tight seal on metal tubing lines to transfer diesel fuel, fuel oil, and gasoline. All are full port, so they do not restrict flow.

Prevent vacuum loss with these airtight, leakproof valves. They open to allow flow in one direction and close when flow stops or reverses.
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.
