How Sprinkler Valves Work

Your controller sends 24V to a valve’s solenoid, which opens it to water that zone, then closes it when the station ends — one valve per zone. In-line solenoid valves do the automatic watering; anti-siphon valves add built-in backflow protection in the same body; and ball valves give you a reliable manual shut-off to isolate the system. Group the zone valves on a manifold inside a valve box for protected, serviceable access. Sizing the box? Read our How to Choose a Sprinkler Valve Box guide.

Valve FAQ

How does a sprinkler valve work?

A controller energizes the valve’s 24V solenoid, which lifts the diaphragm and lets water through to that zone. When the station time ends, the solenoid de-energizes and the valve closes. One valve controls one zone.

What size valve box do I need?

Match the box to the number and size of valves it covers — a single valve fits a round box, while a manifold of two or more needs a rectangular jumbo box with room to service each solenoid. Our valve box guide walks the sizing.

Globe or angle valve?

Both are in-line solenoid valves. A globe valve has the inlet and outlet in a straight line; an angle valve turns the flow 90°, which saves a fitting at the base of a manifold or where the supply comes up from below.

What is an anti-siphon valve?

An anti-siphon valve combines a zone valve with a built-in atmospheric vacuum breaker, so it both controls the zone and provides basic backflow protection. It must be installed at least 6 inches above the highest head and cannot be left under continuous pressure.

Ball valve or gate valve for a shut-off?

A ball valve opens and closes a quarter turn and seals reliably, which makes it the common modern choice for a mainline isolation point. Both isolate flow; ball valves are quicker to operate and less prone to seat wear.
