- Valve Type: Ball

NPT Female × NPT Female × NPT Female: Air, Water
NPT Female × NPT Male × NPT Male: Air, Argon, Helium, Krypton, Neon, Oil, Water, Xenon - Seal Material: PTFE Plastic
Control flow in two directions from a single source—these valves have two handles for independent operation of each outlet. They can direct flow from the center-port inlet to one side-port outlet at full capacity, direct flow to both side-port outlets simultaneously at reduced capacity, or shut off flow to both outlet ports completely. Valves are standard port, so they slightly restrict flow.

Threaded Solenoid Diverting Valves
- For Use With: Air, Argon, Helium, Krypton, Neon, Oil, Water, Xenon
- Seal Material: Buna-N Rubber
These valves operate on electricity to automatically divert flow between ports. All can direct flow from the center-port inlet to either side-port outlet. Valves cannot shut off flow. They require a minimum pressure drop between the inlet and outlet for operation; the upstream pressure must be 10 psi greater than the downstream pressure. The actuator is directly mounted to the valve body to minimize movement and reduce wear.
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.

Wye-Shaped On/Off Valves with Garden Hose Threads
Convert one faucet into two, four, or five convenient outlets. Each outlet has individually operated shutoff valves.
Plastic valves are lighter than brass or zinc valves, and are durable enough to hold up to impacts and abrasion. They have good corrosion resistance.
Zinc valves have good corrosion resistance. Some also have a TPR rubber or plastic coating to protect your hands—the coating keeps valves from getting hot in the sun or cold in the winter.
Brass valves are softer than zinc and plastic, so they’re easier to thread together. They’re also corrosion resistant.
Valves with flexible outlets are easy to install and help keep your hose from kinking.

Diverting Valves with Fire-Fighting Hose Fittings
- Valve Type: Ball
- For Use With: Water
- Seal Material: Buna-N Rubber
Control the flow of water in two directions from a single source—these diverting valves have two balls and handles for independent operation of each outlet. They can direct flow to one side outlet at full capacity while shutting off flow to the second side outlet, direct flow to both side outlets at reduced capacity, or shut off flow to both side outlets. Valves have a brass body for good corrosion resistance. They are for use with fire-fighting hose.
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.
NH/NST (National Hose/National Standard) threads are only compatible with other NH/NST threads. Male NPSH (National Pipe Straight Hose) threads are compatible with female NPSH threads. Female NPSH threads are compatible with male NPSH, NPT, NPTF, and NPSM threads.

Air On/Off Valves
Turn airflow on and off with these valves. They have two balls to independently shut off airflow to one of two outlets from a single source. When closed, they vent air pressure to the atmosphere so you can disconnect air tools safely.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
