Brass Needle Valve F/F

A needle valve meters flow instead of switching it: a tapered stem winds down into a small seat, so a full turn of the knob makes a small change to the flow rather than a large one. Brass body, female BSP at both ends, rated to 500 psi maximum working pressure and 110 degrees C. Three part numbers cover the range: NV10402 for 1/8 BSP, NV10404 for 1/4 and NV10406 for 3/8.

Needle valve or ball valve?

A ball valve is a switch: a quarter turn, open or shut, and anything in between is guesswork that also chews the seat. A needle valve is an adjuster, with a tapered stem and several turns between shut and fully open, so a flow can be set and left. Plenty of rigs want both, one to isolate and one to meter.

What size needle valve do I need?

Order on the thread, not on the flow. The range is 1/8, 1/4 and 3/8 female BSP: NV10402 is the 1/8, NV10404 the 1/4 and NV10406 the 3/8. All three carry the same 500 psi and 110 degrees C ratings.

Metering, isolating and one way valves are all in valves.
