    Threaded Flow-Adjustment Valves with Fire-Fighting Hose Fittings

    Connect these valves to fire hydrants, fire pumps, and fire hoses to adjust the flow of water. Ideal for fighting fires, their internal gate allows unrestricted flow when fully open, unlike globe valves. However, you should only use these valves in emergencies when full flow is needed—they get damaged by throttling over time. They have a nonrising stem that stays in the same spot whether they’re open or closed.

    Valves with a wheel handle take up less space than valves with a speed handle. The included hose cap protects them from dirt and debris. It’s connected to the valve with a chain, so you won’t lose it.
    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.

    Speed Handle—Red Brass Body with Bronze Gate

    Valves with a speed handle can be turned with one hand, unlike valves with a wheel handle. Quickly connect the fittings to hydrants, pumps, and hoses with the easy-to-grip pin lugs on the sides. Tighten them with a hook-style spanner wrench. To prevent kinking when you’re connecting a hose, the fittings swivel until tightened. These valves are red so people know they’re fire valves.
