Yilin YL28009-3 24V AC Irrigation Solenoid Valve
The Yilin YL28009-3 is a 24V AC irrigation solenoid valve with a 3-inch internal thread, a manual ON/OFF control and adjustable flow. It suits irrigation systems run from an AC controller, where one large valve opens and closes a supply line. Yilin's page gives the voltage, connection size and packing data. For a working installation, ask Yilin for the pressure range, a flow curve, the coil's electrical data and the thread standard, and ask for corrected packing weights before you plan freight.

Build my procurement briefSizing the valve for your water flow
The 3-inch thread tells you which pipe the valve screws onto. How much water it passes at your pressure is a separate question, and Yilin's page gives no pressure range or loss curve. Settle both before you order. Working pressure and friction loss in the pipe on either side of the valve are explained in our guide to specifying irrigation hose and pipe.
| Your irrigation condition | What to ask Yilin for |
|---|---|
| Pipe fittings | The thread standard, the mating fitting and a dimensioned connection drawing. |
| Required watering flow | Your flow and the pressure at the valve, checked against a hydraulic curve or written operating limits for this model. |
| Water source and quality | Your water and filtration conditions and any additives, plus Yilin's body and seal materials and water-quality limits. |
| Adjustment and shutoff | How to adjust flow, the conditions it is rated for, and agreed leak and function checks with a minimum-flow and shutoff limit. |

Published specifications
Read each value with its stated conditions, and ask the manufacturer for any limit not listed here.
| Specification | Published value | Meaning / limit |
|---|---|---|
| Electrical identity | YL28009-3; 24V AC in the product title [1] | The coil is AC. Ask for the frequency, inrush and holding current, and which controllers it works with. A 24V DC circuit needs a DC coil. |
| Connection | 3-inch internal thread [1] | Ask for the thread form (such as BSP or NPT), pitch, engagement length and bore. |
| Local operation | Manual ON/OFF [1] | Lets you open or close the valve by hand. Ask for the operating procedure and how it hands back to the controller. |
| Flow adjustment | Adjustable flow, as Yilin describes it [1] | Ask for the adjustment range, minimum operating flow and a pressure-loss curve. |
| Packaging | Colour box; one piece per carton; 30 × 16 × 30 cm carton [1] | Yilin's packing listing. Check it still applies to the coil and connection version you order. |
| Gross/net weight entry | G.W./N.W.: 3.8/3.9 kg, as printed [1] | The printed gross figure is lower than the net. Ask Yilin for measured weights before calculating freight. |
Matching the AC coil to your controller
The product title fixes the coil at 24V AC. For a full electrical match, ask Yilin for the coil frequency, inrush and holding current, connector and wiring details, and the coil's weather protection. Check those against your controller output and cable run. Name your controller, transformer or timer in the enquiry and ask Yilin to confirm in writing that it will drive this valve. If the controller is not chosen yet, the RAIN LING RL-CA08 Eight-Station Irrigation Controller is one station controller you can name in that request.
Ask for the operating instructions for the manual ON/OFF, including how to return the valve to controller operation. Also ask whether the valve fails open or closed, whether the coil has surge protection, and its enclosure rating. Put the answers in the equipment schedule for the job. For a second quote on a controller-switched valve, the RAIN LING EVA/EVD Solenoid Valves are the closest alternative in our irrigation listings.

Packing weights and container loads
Yilin prints G.W./N.W. as 3.8/3.9 kg. Gross weight normally includes packaging, so one of the two figures is wrong. Ask for measured net and gross weights of the current packed valve, with the carton drawing and pallet layout.
Yilin lists 1,950 pieces per 20-foot container and 4,720 per 40-foot. Use these for a first estimate, then get loading limits, pallet count and corrected weights from Yilin before booking freight.

Checking a sample valve
Agree a check plan with Yilin and your installer using your real pipework, controller and water. Set pass limits before the sample ships. Timer and valve suppliers, Yilin among them, are listed in our irrigation section.
Identify the sample
Match the valve marking, coil marking, connector and thread drawing to the production order.
Run it on your circuit
Check the coil datasheet, then switch the valve from your own controller and wiring under the agreed conditions.
Check the water side
Test opening, flow adjustment and shutoff at your working conditions, following a written procedure and agreed limits.
Complete the supply pack
Record current weights, installation and maintenance instructions, spare coils and seals, and the warranty and support terms.

Buyer questions
Will a 24V DC controller switch this valve?
The product title says 24V AC. Ask Yilin whether a DC coil is available, and match the coil datasheet to your controller output. [1]
Is the 3-inch internal thread BSP?
Yilin's page does not name the thread standard. Ask for the drawing and identify the mating fitting before ordering. [1]
What are the maximum pressure and rated flow?
Yilin's page gives neither. Ask for the pressure rating and a flow curve for this model in writing. [1]
Should I swap the printed packing weights?
Ask Yilin for measured current weights instead. The printed gross figure is lower than the net, so one of them needs correcting. [1]
