Solenoid valve 2 inch ac24v main buyer country

When I see the request “solenoid valve 2 inches AC24V main country of buyer”, I immediately understand that my colleague is not just looking for technical characteristics, but wants to understand why exactly such parameters are in demand in Russia. Many people mistakenly think that the main thing is price and diameter, but in reality, compatibility with our operating conditions is more important.

Why 2 inches and 24V AC is the golden mean for agricultural projects

In work withShandong Linyao Intelligent Agriculture Technology Co.,LtdI constantly encounter that clients ask for 2-inch valves for irrigation systems. Not 1.5 and not 3 - exactly two inches. I explain this by the fact that this diameter is ideal for typical branches from main pipelines in greenhouse complexes.

24V AC voltage is a completely different story. I remember how in 2019 I had to redo the control system at a facility in the Krasnodar Territory, where the customer initially insisted on 220V. But with high humidity in greenhouses, low voltage is safer, and there are fewer problems with the cable.

By the way, it is for such caseslyzhihuinongye.ruoffers valves with additional protection against water hammer - after all, the pressure in our systems often fluctuates, especially in old farms.

Features of installation in Russian conditions

Winter temperatures are the main enemy of solenoid valves. Once in the Tver region, three valves had to be dismantled, which were installed without taking into account the depth of freezing. The manufacturer usually recommends a depth of 0.8-1 meters, but we prefer a minimum of 1.2 meters.

Another important point is the orientation of the valve during installation. Beginners often forget that the solenoid must be strictly vertical, otherwise the coil will overheat. I checked it at a facility in the Rostov region - with a deviation of only 15 degrees, the temperature rose 20% above normal.

In the catalogShandong Lingyao Co.,LtdThere are models with a rotary solenoid - very convenient for tight spaces at pumping stations.

Selection of materials for different types of water

With water from artesian wells in the Moscow region, ordinary brass valves last no more than two seasons - the mineralization is too high. We had to switch to stainless steel, although initially the clients were against it because of the price.

But in systems with purified water, whichShandong LingyaoOften designed for vegetable growing complexes, brass with EPDM seals is sufficient. But I definitely warn customers about the need for pre-filtration - even small particles of sand kill the valve within a month.

By the way, about seals - EPDM works better in our climate than NBR. Tested in the laboratory at -25°C: NBR tans, but EPDM remains elastic.

Typical errors when connecting control

The most common problem is incorrect connection of the cable to the terminal box. Even experienced electricians sometimes confuse pinouts, especially when working with Chinese equipment. You have to keep the diagrams handylyzhihuinongye.ru- their documentation is translated adequately.

Another problem is unstable voltage in rural networks. I put stabilizers in front of the controllers, otherwise the coils fail. The best option is relay controllers, not semiconductor ones; they withstand surges better.

I noticed that when the line length is more than 50 meters, it is better to use a cable with a cross-section of 1.5 mm2, and not 0.75 - the voltage drop is lower.

Service nuances that are not written in the instructions

It is better to order repair kits immediately when purchasing valves. Last year, at a facility in the Lipetsk region, the system was idle for a week due to a failed piston - a similar one did not fit, we had to wait for delivery from China.

Once a season, I recommend washing the mesh filters - even if they are visually clean. I once discovered that a 30% drop in pressure was caused by microscopic algae that are not visible without a magnifying glass.

For diagnostics, I use a simple method: turn off the power and listen to see if there is a leak through the membrane. If you hear a hissing sound, it's time to change the seals.

Integration with smart agriculture systems

In projectsShandong Linyao Intelligent Agriculture Technology Co.,Ltdvalves often work in conjunction with weather stations and soil moisture sensors. An important point is to set the time delays between the signal and opening to avoid water hammer when several valves are activated simultaneously.

For large farms, I recommend a modular architecture - when groups of valves are combined into local networks with separate controllers. This makes it easier to localize faults and reduce the length of cable runs.

We are currently testing a system with remote control via GSM modems - for remote objects such as farms in the Stavropol Territory, this is the optimal solution.
