How do you repair a sprinkler control valve?
How to Replace a Valve Solenoid
- Shut off the water supply to the sprinkler system.
- Remove the two wire connectors on the wires leading to the bad solenoid, then untwist the wires to separate them.
- Remove the old solenoid from the sprinkler valve by turning it counterclockwise.
How many volts does a sprinkler valve need?
24VACIrrigation systems utilize a 24VAC electronic signal to initialize a valve's solenoid.
Are sprinkler valves 24v AC or DC?
It's a common mistake to assume sprinkler valves work with DC voltage. While most valves indeed CAN be powered by DC voltage (see below), they are designed to work with AC voltage in the range of 22VAC to 28VAC. That's why if you look at a standard sprinkler transformer, the output is usually AC.
What voltage are sprinkler solenoids?
Most irrigation solenoids operate on AC voltage. Rain Bird voltage specifications are 117 VAC ± 10% (105 - 129) volts. DC volts (VDC) - Direct Current, the normal source is a battery.
How do you check the voltage on a sprinkler valve?
Touch one multimeter lead tip to the common wire on the controller, which is usually white. Touch the other multimeter lead to the screw on the wiring on the defective zone. The reading should be between 22 and 28 V. The normal reading is 24 V.
Are all sprinkler valves 24 volt?
Sprinkler valves are operated electronically using low voltage 24v power generally of 18 gauge wire for residential, and 14 gauge wire for commercial.
Will 12V solenoid valve work on 24V?
Well, I did state "replace 12V supply shown here with 24V supply." Test your solenoid in the intended application with the 12V supply, it may work fine. ' You usually do not need to apply the rated voltage for adequate operation.
How do I know what voltage my solenoid is?

Will a 24vac solenoid work with 24vdc?
As an example, using a 24 VAC rated solenoid valve with a 24 V DC power supply would most likely damage the solenoid because the effective current flowing through the solenoid would be much higher with DC voltage. Unfortunately, there is no fixed factor for derating the power supply voltage.
How many amps does a sprinkler solenoid draw?
Many irrigation valve solenoids have an inrush current (the sudden surge of current, measured in amps, occurring when the solenoid is first energized) anywhere from . 35 to . 70 amps. When the valve is powered, the inrush current will reduce to a hold current, which has a lower amperage value between .
How many watts does a sprinkler valve use?
The controller of the irrigation system uses electricity to turn the valves on and off. A typical residential controller uses about 0.5 Kwh a day while a large commercial controller uses about 1.2 Kwh a day.
How does a 24v solenoid valve work?
Solenoid valves are control units which, when electrically energized or de-energized, either shut off or allow fluid flow. The actuator takes the form of an electromagnet. When energized, a magnetic field builds up which pulls a plunger or pivoted armature against the action of a spring.
How do you test a 24v solenoid valve?
How to Test a Solenoid Coil?Set your multimeter on ohms. If the multimeter is not automatic, set it on 2k ohms. ... Place the probes of multimeter across the pins of a solenoid coil. If you find 3 pins there, one of them is a flat pin which is connected to the ground. ... Read the number on the multimeter.
Can a sprinkler valve be powered by DC?
It’s a common mistake to assume sprinkler valves work with DC voltage. While most valves indeed CAN be powered by DC voltage (see below), they are designed to work with AC voltage in the range of 22VAC to 28VAC. That’s why if you look at a standard sprinkler transformer, the output is usually AC.
Can you use 9V to activate a solenoid?
However, if the rod is already in, 9V is sufficient to hold the solenoid activated. So if you really want to make it work with 9V, you need a circuit that can provide a high impulse voltage; then once the solenoid is activated, you can lower the voltage to reduce the current (hence power) consumption.
Do sprinklers have inductance?
The catch is exactly in the fact that sprinkler solenoids are powered by AC voltage. Because the solenoid is made of a coil, it not only has coil resistance but also inductance. When operated on AC power, the inductance produces significant reactance which cannot be ignored.
Can a sprinkler valve be powered by DC?

Where to install sprinkler valves?
In-line sprinkler valve can be installed in an underground box. Rain Bird. Place them near the timer so you will not have a long wire run. Install a shutoff valve just prior to the control valves. The valves are simply put together with threaded parts; you do not have to glue them.
How high should a backflow valve be above a sprinkler head?
Anti-siphon control valves have their own backflow prevention. They must be positioned at least 8 inches above the highest sprinkler head.
What type of cable do I need to connect a timer to a control valve?
Use low-voltage insulated cable approved for burial (usually AWG-14 or -18) to connect the timer to the control valves. You will need multi-strand wire with enough wires for each valve plus one more to connect the valves to the timer. (So, if you have three valves, you’ll need four-strand wire.)
How to keep sprinklers from getting snagged?
Make use of sprinkler trenches where you can, placing wires underneath the pipes and loosely looping around each valve and bend in the trench. Run the wire above ground when you get to the timer, and secure it to a wall or other surface to keep it from getting snagged.
How many volts does an irrigation controller use?
The irrigation controller tells the valve when to open and close. When the clock reaches the programmed time, 24 volts is applied to the lines running to the solenoid. The current is applied to the solenoid until the clock reaches the end of the programmed time.
What is automatic irrigation valve?
Automatic irrigation valves allow homeowners to turn their sprinklers on and off unattended and without consideration--once the initial programming is done. The valves are controlled by a computerized controller or "clock" and are operated by safe, low-voltage AC power. They do their work in a very hostile environment.
What is the hole in the diaphragm of a valve?
A tiny hole in the middle of the diaphragm allows water into an upper chamber. As long as the pressure is the same on both sides of the diaphragm, the valve remains closed. Inside that upper chamber, a small vent leads to the outflow side of the valve. A small plunger keeps that vent closed and the pressure equalized.
How much pressure can a mechanical valve hold?
It would not be strong enough to open a mechanical valve capable of holding back 40 to 80 pounds per square inch (psi) of water pressure.
How does water flow through a solenoid?
When power is applied to the solenoid, an electromagnet lifts the plunger and water flows through the vent, decreasing the pressure above the diaphragm, which pulls it off the ports. Water flows through the ports, down the pipes and on to the sprinklers. Advertisement.
How to read AC voltage on a voltmeter?
Using the AC voltage reading on your voltmeter, touch one probe to the station terminal you wish to test and the other probe to the C or COM terminal while the station is activated. Typically it does not matter which of the two colored probes goes where, but for consistency, purposes use the black probe for the C terminal and the red probe for ...
How many wires does a solenoid have?
It is no coincidence that the solenoid has two wires and the controller had two screw terminals for you to test. Solenoids have two wires, one for the COMMON wire and one for the station's power wire. Typically COMMON wires are shared throughout irrigation systems to save on wire.
Where should I install a sprinkler controller?
1. Decide where you would like to locate the sprinkler controller. Most residential controllers should be installed indoors, i.e. the garage unless the sprinkler controller is designed for outdoor use.
How many wires do I need for a 5 zone controller?
If you are wiring a 5-zone system, purchase a combination of wires with at least 6 total wires long enough to reach from your controller to the farthest valve. 3.
