This innovatively designed valve by Rain Bird is effectively engineered to handle particles at a low flow rate (45.4 to 1136 L/h) making it ideal for low-flow and drip line irrigation systems.
Please Note: The solenoid handle (pictured) is not included.
Unique Diaphragm Design
Made specifically for drip irrigation systems, this low-flow valve is engineered with a double knife diaphragm to eliminate the need for filtration even at low flow rates (45.4 to 1136 L/h).
The ½” diameter seat lifts higher when water passes through promising flawless operation at low flow rates and the ability to handle all sized particles.
Prevents valve weeping.
Confidently install the filter downstream since these valves will handle any sized particles.
Unmatched Durability Engineered to Last
For strength, impact and weather resistance, the body is made from chemical and UV-resistant glass-filled polypropylene whilst the internal design promises a strong seal between the body and bonnet.
Features an energy-efficient, low-power, fully encapsulated solenoid and an internal plunger with a smart coil design ensuring the plunger and spring cannot fall out.
Outstanding Performance
This premium value product is chosen by professionals as it features a double-filtered diaphragm and solenoid with self-cleaning 90-mesh pilot filters for maximum reliability and grit resistance.
The durable Buna-N rubber diaphragm ensures smooth closing, balanced pressure and less water hammer.
Consistent problem-free performance proved by its history of reliable performance.
Clog-resistant metering orifice.
Easy to Install
External bleed screws allow manual flushing of dirt and debris during installation. Activate the flush mode by turning the external bleed screw half a turn.
Internal bleed screws allow spray-free manual operation. Operate the internal bleed by turning the solenoid counter-clockwise a quarter to a half a turn and re-tighten after use.
Reverse flow, normally closed design.
Performance and Value Combined
Easily access the internal parts of the valve using the removable top without having to disrupt the valve installation.
Accepts a latching solenoid for use with rain bird battery-operated controller

Solenoid Valves Frequently Asked Questions
Which Irrigation Solenoid Valve Do
I Need?
If using a 9V/Battery Operated Controller, use alongside a 9V DC Solenoid Valve to ensure the current is enough to operate the valve. 9V DC Solenoids operate on a lower voltage and have much smaller coils inside the solenoid so should not be used alongside mains-powered controllers.
Top Tip: Contact a qualified electrician before purchasing and installing your components.
Why is my Solenoid Valve not
Working?
A solenoid valve that does not open or shut off water flow when required or is leaking indicates damage to the solenoid or valve. After switching off the water flow and power supply linked to the valve, check the following considerations are met.
Debris built up inside the valve’s internal mechanisms may be causing a blockage or preventing the valve diaphragm from operating as it should. Ensure the valve box is free from any dirt or weed growth clogging any vital mechanisms.
Check the water pressure and flow rate from the water source to the valve are within the range outlined in the product’s specifications. Too much pressure will cause damage and too little will prevent the valve from opening.
A valve may be prone to leaks if the O-ring between the solenoid thread and solenoid port is bent, twisted or perished. Turn your valve to the off position before installing a Replacement Solenoid.
Irrigation Solenoid Valve
Remaining Open
A valve that won’t shut off indicates a problem with the internal plunger where the port has become blocked or filled with debris preventing the plunger from dropping down into the valve. Often cleaning the solenoid port should rectify this problem. After cleaning the solenoid port, switch the solenoid valve off manually or at the controller level. If the valve remains open, the internal mechanisms will need inspecting and further cleaning.
For valves with built-in flow control, turn the flow control down until the valve does eventually close (usually this is achieved by turning in a clockwise direction). Once you have established the required level of flow, leave the flow control in this position. This should allow the valve to work correctly opening automatically when receiving communication from the timer.
Are Solenoid Irrigation Valves
Waterproof?
A solenoid valve should be installed in a dry Valve Box with adequate drainage that is not prone to flooding. This is to maintain the integrity of the valve over time protecting against the effect of thawing and freezing and the risk of electrical wires getting wet. Solenoid valves are designed to cope with some immersion of water, however, they should not be submerged for long periods. HydroSure Solenoid Valves are epoxy encapsulated and designed for maximum moisture resistance and longevity compared with moulded solenoids. Please Note: All electrical wires should be encased in a waterproof Electrical Connector with no exposed wiring – Consult a licenced professional during installation.
How to Replace a Solenoid Valve
The solenoid and solenoid valves are separate components. If the valve is not damaged, you can simply replace the solenoid.
Begin by shutting off any water/power supply to the valve. 2. The wires connecting the old solenoid to the system should be cut off at the connection point making sure to save as much wire as possible that connects to the system but dis-guarding any wire that has corroded or split. 3. Unthread the solenoid from the valve by turning the solenoid counter-clockwise. Once the old solenoid is removed, clean the solenoid port on the valve before installing the new Replacement Solenoid. 4. The new solenoid can be threaded into the solenoid port and rewired to the common wire and zone it controls. Ensure no copper wiring is exposed and each connection is secured using an Electrical Connector.
Top Tip: During this installation, take care not to get any dirt in the solenoid ports or cross-thread the solenoid which will hinder its function.
Why is my Irrigation Solenoid
Valve Not Opening?
Check the water supply is switched on and that there are no flow restrictions such as a closed valve or a leaking connector.
If using a valve with built-in flow control, ensure the valve is not closed/partially closed preventing water from reaching the sprinklers.
Most solenoid valves allow you to remove the valve bonnet. Before undertaking any maintenance, turn off the water supply to your valve box and drain the irrigation line. Then, remove the solenoid lid by unthreading the screws. Check if any grit or large particles have become lodged inside. The debris can be removed or flushed from the valve and the lid refitted.
A low flow rate or low pressure generated from the tap can cause a valve to remain closed. To combat this, manually open the valve using the bleed screw to allow water to run through. If the valve remains closed, this indicates an electrical problem and it is advisable to contact a licenced professional to carry out maintenance.
