As the population continues to increase, global food production in all parts of the world needs to increase. However, the effects of climate change continue to make it difficult to achieve optimal crop yields in some places, so best agricultural practices including irrigation are required. Agricultural irrigation can optimize water flow through the use of various drive and control valves to ensure that only the optimal amount of water is used and not wasted. Of course, our COVNA can provide these pneumatic and electric valves for small and large irrigation applications. In this article, we will learn how to select and apply COVNA actuators to regulate water flow in irrigation practice.

Where can actuators be used in the agricultural irrigation industry?

Electric valves and pneumatic valves have a wide range of applications in the agricultural irrigation industry, but it takes some thinking and consideration to find their best use. The biggest use is to control water flow through automated control loops. These loops require humidity sensors to analyze the moisture level of the soil to open/close the water valve accordingly. In this case an on/off or flow control valve can be used.

When using control valves, valves such as stop valves and angle valves are usually the first choice in agricultural irrigation. Compared with other valves, these valves have a tighter closure. COVNA actuators are suitable for applications with these valves because they meet requirements such as torque, general wear resistance, etc., because these applications may require the actuator to be outdoors, etc. In addition, since the valve can be operated in manual mode when the power is off, it is flexible and can be operated continuously without obstacles.
