When you see “2.5 inch dc24v solenoid valve” in an application, the first thing that comes to mind is the standard situation. But behind this simplicity there are a lot of pitfalls, which only those who actually assembled the systems know about. Many people think that the main thing is matching the diameter and voltage, but in reality the fun begins.
In work withsolenoid valve 2.5 inchI often come across the fact that people do not take into account the difference between the nominal bore and the actual diameter. We had a case at a site in the Rostov region - the customer complained about insufficient flow, although according to the documents everything matched. It turned out that the pipes were narrowed, but the specifications were silent about this.
Another point is the threaded connection. For 2.5 inches there are both pipe and metric threads, and the pitch may differ. Once I had to urgently look for adapters, because a valve with a metric thread arrived at the site with piping. Now I always clarify this point with manufacturers, for example withShandong Linyao Intelligent Agriculture Technology Co.,Ltd- they usually indicate such details in the documentation.
The material of the housing is also important - agricultural projects often require a stainless steel option, but it is much heavier and more expensive. You have to weigh it: if the water is with fertilizers, then it’s stainless steel, if it’s clean water, then it’s brass. But here we are already looking at the project budget.
24 volt DC is considered a safe option, and this is true. But many people forget about the voltage drop in long lines. I remember at a greenhouse complex near Voronezh they installeddc24v valvesat a distance of 200 meters from the control unit - and they refused to work normally. I had to re-arrange the cable with a larger cross-section.
Another nuance is the starting current. When turned on, the solenoid consumes significantly more than in operating mode. If the power supply is fitted end-to-end, the valve may not open. A standard mistake is to set the unit to 1A, but the starting current can reach 1.5-2A for a split second.
Polarity seems like a small thing, but some models are sensitive to polarity reversal. It’s not always written in the specifications; you have to check it experimentally. Good producers likeShandong Lingyao, protective diodes are usually installed, but it is better to clarify this separately.
When installingsolenoid valve 2.5 inch dc24vThe need for filtration is often underestimated in irrigation systems. Sand particles even 0.5 mm in size can damage the valve seat. We had the unfortunate experience of having to replace three valves in one season due to poor filtration.
Installation orientation - vertical or horizontal? Manufacturers often write 'preferably vertically', but in practice sometimes they have to be installed horizontally. The main thing is that the coil is on top, otherwise there may be problems with air removal.
Service in the field - it is necessary to provide for the possibility of quick dismantling. We usually install quick connects before and after the valve. It is especially important for agricultural enterprises, where a simple system during the irrigation season is expensive. On the websitehttps://www.lyzhihuinongye.ruThere are good options for such solutions.
When integrating into smart agricultural systems, the issue of protocol compatibility often arises.DC24V solenoid valveusually controlled by simple relays, but if we are talking about a complex system likeShandong Linyao Intelligent Agriculture Technology Co.,Ltd, then there may be nuances with the response time.
In one project of an intelligent agricultural park, they were faced with the fact that the controller was producing pulses that were too short for control - the valves did not have time to operate. I had to adjust the delays in the software.
Electromagnetic compatibility - valves may operate falsely near power cables. The solution is shielded cables and proper routing. This is critically important for large facilities.
Winter operation is a major challenge for any solenoid valve. Even with drainage holes, remaining water can freeze and rupture the housing. In systems where water is turned off in winter, it is necessary to ventilate with air.
The quality of electricity in rural areas - the stability of 24V may be disrupted due to surges in the network. Install stabilizers, otherwise the coils will quickly fail. From experience, it is better to overpay for a high-quality power supply than to change valves every season.
The service life depends greatly on the manufacturer. Chinese valves for 2,000 rubles and European ones for 10,000 - the difference is not only in price. But for many agricultural projects, especially within the framework of budget financing, the optimal options are fromShandong Lingyao- quite reliable at an adequate price.
Last year, on the project of a smart greenhouse complex, they used exactlysolenoid valve 2.5 inch dc24vfromShandong Linyao Intelligent Agriculture Technology Co.,Ltd. The system worked with varying success - in the first months there were complaints about sensitivity to water quality.
After installing additional fine filters, the problems disappeared. An important point is that the manufacturer provided technical specifications, according to which we were able to select the optimal filters. This is rare; usually such data have to be obtained experimentally.
Now these valves have been working for the second season, there are no complaints. One interesting thing is that energy consumption turned out to be lower than stated, which is important for objects with autonomous power supply. But the response time is slightly longer than its European counterparts - by 0.2-0.3 seconds. For most agricultural tasks it is not critical.
