The Toro P-220 1.5" Globe/Angle AC Valve is engineered to handle the brutal demands of large-scale commercial landscapes and agricultural operations. Constructed from heavy-duty, glass-filled nylon, this valve scoffs at the pressure spikes that shatter standard residential equipment, effortlessly maintaining structural integrity up to a massive 220 PSI.
Beyond raw durability, the P-220 features Toro’s proprietary Spike-Guard™ solenoid. This ultra-low-power module drastically reduces electrical draw, allowing you to run twice as many valves simultaneously on a standard AC irrigation controller without overloading the transformer. Paired with a self-cleaning stainless steel metering rod and a massive 110 GPM flow capacity, this valve provides relentless, hassle-free performance year after year.

Follow these steps to safely plumb and wire your commercial Toro P-220 valve.
Step 1: Plumb the Connections
Using high-quality Teflon tape, thread 1.5" male PVC adapters into the large inlet and outlet ports. Ensure the directional arrows on the valve body perfectly align with the direction of your mainline water flow.
Step 2: Install in a Valve Box
Seat the fully plumbed valve inside a heavy-duty underground rectangular valve box over a deep bed of gravel to ensure proper drainage.
Step 3: Connect the Wiring
Connect one wire from the Spike-Guard™ solenoid to your 24V controller's common wire, and the other solenoid wire to the specific station wire. Securely seal all connections using waterproof wire nuts.
Step 4: Activate and Test
Turn on your main water source. You can manually activate the zone to test the connection by turning the solenoid a quarter-turn counter-clockwise or using the controller.
What is the advantage of the Toro Spike-Guard solenoid?
The Spike-Guard solenoid features incredibly low power consumption compared to standard models. This reduces electrical strain, allows twice as many valves to run simultaneously, and lets you use thinner gauge wire on long runs.
Can I use this 1.5" valve on a standard residential system?
While highly durable, this valve is designed for large commercial flows. It requires a minimum flow rate of 30 GPM to operate correctly, which far exceeds the capacity of a typical residential 3/4" water meter.
How does the self-cleaning mechanism work?
The valve utilizes a stainless steel metering rod positioned inside the diaphragm. Every time the valve opens and closes, the physical movement of the rod actively clears away grit and debris from the metering port.
Does this valve have flow control?
While some Toro P-220 models feature a manual flow control handle, this specific configuration operates as a standard high-capacity globe valve without an adjustable top flow dial.
Why is mid-May the critical time to upgrade to commercial valves like the P-220?
Mid-May is the final window for commercial property managers to stress-test their heavy-duty mainlines. Upgrading to the P-220's massive 110 GPM capacity now ensures your system can deliver the massive water volume required before brutal summer evaporation rates hit.
Discovering that a standard valve can't handle the flow demands of a large turf zone in late June can result in thousands of dollars in landscape damage. Installing high-capacity valves in the spring guarantees summer reliability.
