Heyue Electric Flange Butterfly Valve for the Agricultural Irrigation
In December 2025, Heyue received an order for over 2000 sets of electric flanged butterfly valves from a customer in the Middle East. These electric flanged butterfly valves will be used in an agricultural irrigation project.
Many customers may wonder why electric flanged butterfly valves are widely used in agricultural irrigation. Heyue technician expert provides a step-by-step analysis as below,
A modern automated irrigation system typically includes:
Central controller/IoT gateway → (via wired or wireless network) → Electric flanged butterfly valve → Controls water flow in pipes → Irrigates field crops.
Simultaneously, sensors (soil moisture, weather) feed data back to the controller, forming a closed-loop control system.
Electric butterfly Valves Application scenarios in agricultural irrigation
In agricultural irrigation projects, electric flanged butterfly valves are widely used in several major scenarios:
1. Main pipe and branch pipe flow control
Regional rotation irrigation: In large fields or different crop zones, the automatic switching of irrigation areas is achieved through the opening and closing of electric butterfly valves, enabling precise rotation irrigation scheduling.
Pressure regulation: Installed at key points in the pipeline, it stabilizes the pipeline network pressure, preventing abnormal operation of sprinklers due to insufficient or excessive water pressure at the end of the system.
2. Pumping station and water source management
Water pump linkage control: Linked with the water pump motor, it achieves smooth start and stop, preventing water hammer impact on the pump and pipes.
Reservoir/water tank inlet/outlet control: Automatically manages the replenishment and supply of water sources.
3. Integration into intelligent irrigation systems
As a core execution unit, it receives commands from the controller or IoT platform, and works in conjunction with soil moisture sensors, weather stations, flow meters, etc., to achieve on-demand automatic irrigation.
4. Filtration system and fertilization system
Automatic backwashing control: Used to control the opening and closing of backwashing valves, enabling automatic cleaning of filters.
Fertilization valve control: Precisely controls the opening and closing of the fertilization pump or injection valve, achieving integrated water and fertilizer management.
Electric flange butterfly valve Main Advanctage and Value in agricultural irrigation
High Efficiency Water Saving and Precise Control
It can precisely control the on/off state (fully open/fully closed) or adjust the flow rate by adjusting the opening degree, avoiding water resource waste and meeting the water requirements of different crops.
Significant Labor Savings and Improved Management Efficiency
No manual on-site valve operation is required, especially suitable for large-area and complex terrain irrigation areas. It can be centrally managed remotely through a central control room or mobile app.
High Reliability and Adaptability to Harsh Environments
The flange connection is robust and has good sealing performance, preventing leaks. The valve body material (such as cast iron, ductile iron, stainless steel) is corrosion-resistant and can withstand the fertilizers, pesticides, and other chemicals commonly encountered in agricultural irrigation, as well as outdoor environments.
Protection Rating: High-quality products have a motor protection rating of up to IP67, which is dustproof and waterproof, suitable for outdoor work.
Easy to Implement System Automation and Intelligence
Standard signal inputs (such as 4-20mA, 0-10V) or communication interfaces (such as Modbus) facilitate connection to various automation control systems, making it a key component for smart agriculture.
Technical selection of electric butterfly valves
Diameter and Pressure Rating
Select based on pipe size (DN) and system working pressure (PN), leaving a certain margin.
Valve Body and Seal Material
Valve body: Ductile iron is commonly used; stainless steel is available for high corrosion resistance requirements.
Valve seat seal: EPDM (ethylene propylene diene monomer rubber) is suitable for clean water and fertilizer solutions; NBR (nitrile rubber) has better oil resistance. Consider media compatibility.
Electric Actuator Selection Parameters
Power supply: Commonly AC380V, AC220V, or DC24V. For outdoor locations without mains power, a solar power + DC motor solution can be selected.
Control method:
On/Off type: Receives on/off signals to achieve full opening or full closing.
Modulating type: Receives analog or pulse signals to achieve arbitrary opening degree adjustment.
Protection rating: IP65 or higher is recommended for waterproof and dustproof protection.
Optional functions: Valve position feedback signal (for remote status monitoring), manual operation mechanism (for emergency manual operation in case of power failure), power failure protection (the valve can maintain its original position or return to a safe position in case of power failure).
How to Installation and Maintenance of the electric butterfly valves
During installation, ensure that the pipe flanges are aligned parallel to avoid stress distortion. Ensure sufficient space is reserved for installation and maintenance.
Regularly check the actuator seals, gearbox lubrication, and valve operation.
