Precision Flow-Adjustment Valves with Solder-Connect Fittings

- Valve Type: Needle
- For Use With: Water, Oil, Air, Argon, Helium, Krypton, Neon, Steam, Xenon
Solder these valves to tubing for a permanent, leak-tight connection. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Valves have a 316 stainless steel body for excellent corrosion resistance. All have metal-to-metal seats that resist temperature fluctuations. They have a nut that can be tightened to compress the packing if it leaks.
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.
