Needle valve
1/4 - 9/16" Rego Europe

These valves are high quality, "true'' throttling valves. Unlike most
so-called needle valves, both the body seat and stem are tapered to
provide fine, precise control over a wide range of adjustment without
stem galling.
The 1224 may be used as a small, inexpensive shut-off valve between
a pressure gauge and bulk storage container to allow for convenient
gauge replacement.
The 1314, 1316 and 1318 provide taper pipe thread by left hand hose
connection threads and are useful in a wide range of torch and fuel
burner applications where an accurate throttling action is required.
