    Precision Flow-Adjustment Valves with Solder-Socket Fittings

    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)—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.
