This month's ranking
Open and close water flow per zone on the controller's command.
With over 2,400 reviews, it's by far the best-selling valve in this category — which also means more spare parts and installation guides are available if something fails. 3/4" FPT thread, normally closed like most residential valves, and compatible with any 24V AC controller, not just Orbit's own.
Important: this is NOT a complete valve, it's the replacement solenoid (the coil) for Irritrol valves in the 2400, 2500, 2600, and 700 series. It makes sense to buy this if your current valve stopped opening or closing but the valve body is still in good shape — replacing just the solenoid is cheaper than swapping the whole valve.
Unlike the in-line Orbit 57280 valve in this ranking (which goes underground), this is an 'anti-siphon' valve: it installs above ground level, typically screwed directly onto a spigot, with a built-in vacuum breaker — required by code in many areas when a valve sits near a potable water source. 3/4" thread, standard 24V AC, compatible with any controller. Nearly 900 bought in the past month.
