Toro Irrigation Valves

The right Toro irrigation valve depends on your system’s flow rate, pipe size, and the number of sprinkler heads in the zone. For most residential systems, a 1-inch Toro valve is perfectly acceptable because it provides enough flow for typical rotor or spray zones. Smaller 3/4-inch valves may work for low-flow drip or small spray zones, while larger 1 1/2-inch or 2-inch valves are more common in commercial systems.

A pressure regulator may be necessary if your irrigation system has high or fluctuating water pressure. While many Toro irrigation valves can handle normal residential pressure levels, excessive pressure can cause misting, pipe stress, leaking sprinkler heads, and uneven watering. Adding a pressure regulator can help protect valves, rotors, spray nozzles, and drip irrigation components. Also note that some Toro spray bodies and rotors already include built-in pressure regulation.
