Solenoid valve 1.5 inch dc24v

When you see the specification “solenoid valve 1.5 inches dc24v”, it seems - what’s so complicated? But in practice, even experienced installers sometimes confuse the tightening torque of the thread and the orientation of the coil. I remember how at a facility in the Krasnodar region three valves had to be urgently replaced due to condensation in the coils - the manufacturer declared IP67, but in fact they refused after rains.

Design features

Diameter 1.5 inches is not just a number. For drip irrigation systems, this size often becomes a problem area: if you take a valve with a narrowed passage, the pressure drops catastrophically. Last year we encountered exactly this when launching a greenhouse complex near Voronezh - we had to redo the piping because the designers did not take into account real pressure losses.

A 24V DC coil would seem to be an ideal option for automation. But here’s a nuance: many people forget about the starting current. When several valves are turned on simultaneously, the converter simply goes into protection. You have to set a step start or increase the power of the power supply by 30-40%.

Particularly critical forsolenoid valve 1.5 inch dc24vquality of seals. In our region, they once used valves with EPDM cuffs - after a season they began to leak. It turned out that the manufacturer saved on the material, although the documentation was labeled “food grade rubber.”

Installation subtleties

When installing, I always pay attention to the flow direction arrow. It would seem elementary, but it is on 1.5-inch valves that I often see inverted specimens - apparently due to the symmetry of the body.

I make sure to leave access to the reel - even the most reliable manufacturers have failures. На объектеShandong Linyao Intelligent Agriculture Technology Co.,LtdThey just used a modular design, where replacing a coil takes about two minutes - very convenient for service.

Another important point is protection against water hammer. For 1.5-inch valves this is critical, especially in long pipelines. I once saw two valves blown off during an emergency power outage - now I always recommend installing dampers.

Electrical part

24V DC voltage is safe, but requires high-quality wiring. Copper conductors with a cross-section of at least 1.5 mm2, even if the manufacturer allows less - voltage losses in long lines significantly affect operation.

I noticed an interesting feature: somesolenoid valve 1.5 inch dc24vThey are sensitive to polarity, although in theory direct current should work in any connection. This is especially true when using Chinese controllers.

Protection against coil overheating is a point that is often missed. In the hot climate of Crimea, we somehow encountered the fact that the valves were turned off at the very peak of watering - we had to add cooling radiators.

Practical cases

Last season, we set up an automation system for vegetable farming in the Rostov region. We used valves of this exact size - 1.5 inches. It turned out interesting: during test runs everything worked perfectly, but at full load it began to malfunction.

It turned out that the problem was with the quality of the water - small particles of silt were clogging the fine filters. We had to reconsider the entire water treatment system. By the way, on the websitelyzhihuinongye.ruThere are good solutions on this issue - they specialize in complex projects.

I also remember the case of freezing - the valves were installed in an unheated room, and the winter turned out to be cold. We had to urgently add heating cables. Now I always check the operating temperature conditions.

Hardware Compatibility

When integrated with controllersShandong Linyao Intelligent Agriculture Technology Co.,LtdI noticed an important detail: some models require additional drivers for control, although direct compatibility is stated. This is especially true for older modifications of controllers.

An interesting experience was using wireless modules - for 1.5-inch valves this turned out to be not the best solution. The current consumption during operation created interference in the radio channel.

Now we are increasingly moving to intelligent systems, where everyonesolenoid valve 1.5 inch dc24vhas feedback. More expensive, but you can see the real state of each node - especially important for distributed irrigation systems.

Maintenance

Once a season I always take apart a couple of valves for inspection - even if there are no obvious problems. I pay special attention to the plunger and seat - these are the components that fail first.

When replacing, I always use original spare parts - experiments with analogues usually end in additional costs. By the way, Chinese manufacturers often have compatibility problems even within the same model range.

I recently discovered preventative flushing without disassembly - through special technological holes. Saves time, although it does not replace full service.

Development prospects

Now we are seeing a trend towards reducing energy consumption - modern modelssolenoid valve 1.5 inch dc24vconsume 30-40% less than five years ago. This allows the use of more compact power supplies.

An interesting direction is 'smart' valves with flow and pressure sensors. In projectsShandong Linyao Intelligent Agriculture Technology Co.,LtdSuch solutions are already showing good results in system diagnostics.

I think that in the coming years we will see more integration with analytics systems - when the valve does not just open/close water, but is involved in optimizing the entire technological process.
