Needle Valve - Female by Female Connection
General FAQ
Needle valves control fluid movement accurately, hence the name flow control valve.
When the handle is turned on and the stem is being rotated, the needle rises up from the seat and fluid flows through. This allows maximum accuracy as the tiniest change of the needle will affect the fluid movement.
The design of the seat and needle helps to avoid any gap for the fluid movement when the needle is put into place.
- Size availability from 1/4” to 1”.
- Made of stainless steel 316.
- High working pressure (up to 6000 PSI).
- Users can regulate fluid movement precisely
- Effectiveness & efficiency.
- The precision feature of needle valves reduces the chances of leakage, breakage, and overuse.

This is not a very good needle valve I'm trying to throttle carbon dioxide and first thing that happened is the seal around the valve shaft leaked so I tightened up the packing then it will hardly close you should not have to put any pressure on a good needle valve to stop flow but this thing I had to use some force to get it to close up completely so to me its junk Im taking it out and putting a ball valve in its place which will be better than this thing by far .

Looks hefty but it leaks on the inlet side through the threads. I tried a bushing and a nipple. Same problem with each so I’m confident it’s the needle valve. I’m 24 hours away from leaving to sail to the Bahamas and I can’t replace this. Only running 800 psi for our desalinator. Very disappointed!See my water maker build on YT “Salty Escapeâ€

No sirve, dice que soporta 6,000 PSI, pero con 3,000 - 4,000 PSI no trabaja, deja ir todo.

Used in an RO system and was surprised how hefty it was. The valve only turns about 70% of one turn, I thought it would have 2-3 turns in it. Makes for a very small window between full off and full on. Overall, solid quality and after several days of being in or near the salt water, it only has a couple minor rust spots (as expected, stain "less" not stain "proof"). Overall, good quality for the money!

Works great for my 3K air setup. Tighten packings if required.
