    Threaded Precision Flow-Adjustment Valves with Gauge Ports

    Image of Product. Front orientation. Flow-Adjustment Valves. Threaded Precision Flow-Adjustment Valves with Gauge Ports.
    With a gauge port on each side of these valves, you can install two pieces of instrumentation equipment to simultaneously monitor multiple media properties without interrupting flow. 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.
    Metal-to-Metal Seat—Metal-to-metal seats resist temperature fluctuations.
    Bubble-Tight Soft Seat—Bubble-tight soft seats provide a tighter seal than metal-to-metal seats when the valve is completely closed.
    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.
