The color-coded threads and numerical markings on these valves ensure consistent and repeatable settings. One full revolution of the handle reveals a new color to indicate the set point. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Valves have metal-to-metal seats that resist temperature fluctuations.

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.
