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.

High-Flow Threaded Check Valves

To achieve the maximum possible flow, internal components are designed to reduce flow resistance. These valves open to allow flow in one direction and close when flow stops or reverses. A removable cap provides easy access to internal components for maintenance.

Repair kits include everything you need to rebuild the valve.

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.

Adjustable-Angle Wye

Anodized aluminum resists corrosion and wear better than uncoated aluminum and has a finished appearance.

Black powder-coated aluminum blends in with backgrounds and hides dirt and grime.

Adjustable-angle fittings can be positioned at any angle. Tighten the set screw to secure.

Fittings that meet UL 2703 are approved for use in solar rack mounting systems.
