    Low-Pressure Threaded Flow-Adjustment Valves

    Use these valves for boiler maintenance and other low-pressure plumbing applications. They gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. All have a rising stem that lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off.
