The Six Outlet Automatic Distribution Valve (Without Cam) is a mechanical marvel designed for large agricultural, nursery, or multi-zone landscape systems. Also known as an indexing valve, this unit allows you to run up to six distinct irrigation zones using only one central timer and one main water source. It operates purely on water pressure, saving you the massive expense of buying multiple electric valves and trenching hundreds of feet of electrical wire.
Every time your central pump or upstream valve shuts off, the internal mechanical distributor drops down. When the water pressure returns, it ratchets over to the next outlet in the sequence. By pairing this valve body with the correct internal cam, you can easily customize the unit to run 3, 4, 5, or 6 zones.
Detailed specifications for system planning.

Follow these critical rules when installing your indexing valve.
Step 1: Install the Correct Cam
Remove the top screws, open the housing, and insert the specific cam (3, 4, 5, or 6 zones) you purchased separately. Securely reattach the lid.
Step 2: Position at the Highest Point
The valve must be installed at the highest elevation point of your entire irrigation system. If it is installed lower than the emitters, water will backflow, preventing the internal mechanism from fully dropping and switching to the next zone.
Step 3: Glue the Connections
Because the valve body is made of ABS plastic, you MUST use All-Purpose Cement (not standard PVC glue) to attach your PVC pipe. Allow the glue to cure for a minimum of 12 hours before turning on the water.
Step 4: Cap Unused Outlets
If you are using a 3, 4, or 5-zone cam, you must plug the unused outlets. Glue a 12-inch length of PVC pipe into the unused port, attach an end cap, and drill a tiny 1/8" hole in the cap to allow for internal drainage.
Step 5: Program the Timer Delay
Your master timer or pump relay must be programmed with a minimum one-minute delay (OFF time) between cycles. This allows the system pressure to drop to zero so the cam can properly advance to the next outlet.
Does this distribution valve require electricity or a timer?
The distribution valve itself is completely mechanical and requires no electricity. However, it relies on a single upstream timer, pump, or master valve to turn the water pressure on and off to trigger the zone changes.
Why is water leaking out of the other zones while one is running?
A small amount of seepage or flow between the outlets while the system is pressurized is a normal characteristic of the internal indexing mechanism and does not indicate a defective valve.
Why isn't my distribution valve switching to the next zone?
The valve will fail to switch if there is backpressure holding the cam up. Ensure the valve is installed at the highest point in your system and that your timer allows a full 1-minute "off" delay between runs.
Can I use standard PVC cement to install this valve?
No. The body of this distribution valve is constructed from ABS plastic. You must use a high-quality All-Purpose Cement designed to bond ABS to PVC, and allow a 12-hour cure time before pressurizing.
Why is mid-May the ideal time to install an automatic distribution valve?
As spring expansion peaks and large agricultural or nursery operations finalize their planting grids in mid-May, installing an indexing valve immediately resolves the issue of a maxed-out water source by effortlessly splitting heavy volume across new zones before the brutal summer heat demands daily watering.
This listing is for the valve body ONLY. You must purchase a Valve Cam (available in 3, 4, 5, or 6 zones) separately to make this a functional unit.
