Key features and benefits

Precise stroke control enables stepless valve adjustment

Irrigation valves require precise control of the opening angle to meet varying irrigation needs—slightly open for low-flow irrigation, fully open for flood irrigation, and quickly closed for emergency shutoff. Our linear actuators provide precise stroke control and extremely high repeatability, allowing valves to stop precisely at any opening position. Combined with GPS positioning and soil quality data, the system can precisely allocate water resources to specific areas, achieving true precision irrigation.

High protection rating, designed to withstand humid and water-submerged environments

Irrigation valves are constantly exposed to outdoor, humid environments and may even come into direct contact with water, placing extremely stringent demands on the protection rating of electrical equipment. Our linear actuators feature a high protection rating (IP66 or higher), providing full resistance to the ingress of moisture, mud, and dust. Constructed from corrosion-resistant materials and featuring a fully sealed design, they ensure stable and reliable performance even in environments with prolonged exposure to water and soil.

Long service life and maintenance-free operation, reducing total lifecycle costs

Valves in rivers and farmlands are often located in remote areas, making routine maintenance extremely inconvenient. Our linear actuators feature a maintenance-free design with no hoses, pumps, or compressors. The all-electric solution completely eliminates the risk of oil leaks in hydraulic systems and the issue of aging piping in pneumatic systems. Validated through tens of thousands of endurance tests, they ensure stable operation throughout the equipment's entire lifecycle, minimizing maintenance requirements.

Low-power operation, suitable for solar-powered applications

Irrigation valves and river sluice gates in remote areas are typically powered by solar energy, which imposes extremely strict requirements on energy consumption. Our electric actuators consume power only during the instant of valve operation and have extremely low power consumption in standby mode. These low-energy characteristics make them perfectly suited for green energy power solutions.

Built-in Hall sensors enable precise control for customers

Our actuators feature built-in Hall sensors that provide real-time feedback on stroke position and operational status via pulse signals. This allows customers' irrigation management systems to precisely monitor the valve's real-time opening degree and achieve accurate closed-loop control. The real-time feedback from the Hall sensors provides a precise basis for making refined irrigation decisions—from real-time monitoring of valve opening to accurate water volume measurement, every step is executed with precision under closed-loop control.

Remote monitoring and control, empowering smart agriculture

Our electric actuator solutions allow farmers to remotely monitor and adjust valves. By combining the actuator's position feedback data with GPS tracking systems and soil quality indicators, the system can precisely allocate water resources to specific areas. This remote, intelligent approach to irrigation management enables farmers to carry out precise irrigation scheduling across large tracts of farmland without ever leaving their homes.

Richmat's engineers provide end-to-end technical support—from needs assessment and solution design to product delivery—ensuring that every drop of water meets every inch of farmland with precision through our reliable linear drive systems.

Other Applications

Fertilizer spreaders

Fertilizer spreaders are the core equipment for precision fertilization. Traditional spreaders typically rely on mechanical dampers or manual valves to adjust fertilizer output, with operators relying on experience to operate them. This makes it difficult to achieve variable-rate fertilization based on soil nutrient distribution and crop growth needs—over-fertilization leads to waste and environmental pollution, while under-fertilization reduces crop yields. Modern precision agriculture requires spreaders to integrate with GPS positioning and soil quality data to achieve "fertilization on demand."

Our linear actuators are precision drive components specifically designed for fertilizer discharge control in fertilizer spreaders. By receiving commands from the spreader's control system, the actuators precisely control the opening and closing of the fertilizer discharge port and the tilt angle of the spreading disc, enabling accurate fertilizer metering and variable-rate application.

Agricultural pesticide sprayers

Agricultural pesticide sprayers are indispensable plant protection equipment in modern agricultural production. On traditional sprayers, the boom height and nozzle angle are typically adjusted manually, requiring the operator to stop frequently and get out of the vehicle to make adjustments, which results in low operational efficiency and makes it difficult to ensure adjustment accuracy. More critically, hydraulically driven boom adjustment systems carry the risk of pesticide mixing with hydraulic fluid and leaking—if a line ruptures, the fluid will directly contaminate farmland and crops.

Our linear actuators are precision drive components specifically designed for the various operational functions of agricultural pesticide sprayers. By receiving commands from the sprayer's control system, the actuators precisely control the extension and retraction of the spray boom, as well as the height and angle adjustments of the nozzles. The all-electric solution completely eliminates the risk of hydraulic fluid leaks while enabling more precise and responsive adjustments to the sprayer's configuration.

Combine harvesters

Combine harvesters are the most complex and essential harvesting equipment in modern agricultural production. During operation, the operator must frequently adjust parameters such as concave clearance, auger height, and straw spreading angle based on crop variety, maturity, moisture content, and field conditions—as the threshing requirements for corn and wheat differ, and variations in crop moisture content between morning and evening also require different handling methods. Traditional hydraulic adjustment systems feature complex piping and suffer from response lag, making it difficult for operators to perform precise adjustments while driving.

Our linear actuators are precision drive components specifically designed for the various adjustment functions of combine harvesters. By receiving commands from the control system or the cab control panel, the actuators precisely adjust key parameters such as concave clearance, auger height, and straw spreading angle. Compared to hydraulic systems, electric actuators offer faster response times and more precise control, allowing the operator to perform all adjustment operations from the comfort of the cab.
