DJI Agras T50 T25 Solenoid Valve for Spraying System – PN 00000356

The DJI Agras T50 T25 Solenoid Valve (Part Number 00000356) is a precision electromechanical component, developed to act as the ultimate flow control mechanism in the latest generation of agricultural spraying systems. Designed specifically for the DJI Agriculture T50 and T25 platforms, this valve is responsible for ensuring total system tightness and instantaneous control of the outflow of pesticides and liquid inputs, eliminating unwanted dripping and optimizing application per hectare.

Context and Importance in the Aerospace Sector

In the agricultural drone sector (heavy-lift UAVs), operational efficiency is measured by application precision and flight system integrity. The solenoid valve is not just an accessory, but a critical fluid control component. In modern agricultural aviation, any failure to close a spray nozzle can result in cross-contamination of crops, waste of expensive inputs, and environmental risks.

The introduction of high-response solenoids in the Agras T50 and T25 lines has enabled precision agriculture to reach new levels of automation. These components withstand the high pressures generated by the booster pumps of the centrifugal spraying system, ensuring that the drone responds with millimeter precision to mission software commands based on variable application maps.

What it is and how it works.

The 00000356 solenoid valve operates using a classic electromagnetic principle adapted for harsh operating conditions. When the drone's control system sends an electrical signal, an internal coil creates a magnetic field that displaces a plunger, allowing fluid to pass through. When the current is interrupted, a high-strength return spring instantly seals the passage.

This specific model has been enhanced to handle the corrosive nature of various agricultural chemicals. The opening and closing response time is measured in milliseconds, which is vital for drones flying at speeds exceeding 7 m/s, where a one-second delay can mean several meters of application off the intended target.

Operational Applications in Drones

Real-Time Flow Control

The primary application occurs during automated spraying missions, where the valve works in conjunction with the detection radar and centrifugal nozzles to interrupt the flow as soon as the drone reaches the edges of the application area (geofencing) or during return-to-base maneuvers.

Anti-Drip System

Unlike simple mechanical systems, the electric solenoid ensures that residual pressure in the hose does not cause dripping after the pump is switched off, protecting the crop during movement between plots.

Strip and Spot Spraying

In missions that use artificial intelligence to identify specific weeds, the solenoid valve allows for ultra-fast activation of the spray only on the identified target, saving up to 90% of chemical product compared to application over the entire area.

Technical and Operational Benefits

• Operational Reliability: Tested to withstand thousands of activation cycles under temperature variations, maintaining the integrity of the internal seal.
• Shut-off Precision: The immediate hermetic seal prevents chemical waste, ensuring that the applied dosage exactly matches what was planned in the management software.
• Reduced Field Failures: Constructed with reinforced polymers and oxidation-resistant metals, it minimizes clogging due to pesticide crystallization.
• Simplified Integration: Plug-and-play connector compatible with the original Agras series data and power bus.
• Performance Optimization: Low power consumption, preventing overload on the drone's intelligent power system.

Key Technical Differentiators

The key difference between this valve and generic components lies in its chemical and physical compatibility . The valve body is manufactured from high-density materials that resist UV degradation and abrasion from suspended liquids. Furthermore, the internal design has been optimized to facilitate flow (low pressure drop ), ensuring that the pressure generated by the pumps is delivered almost entirely to the nozzles.

The internal seal uses industrial-grade elastomers that do not expand or deform in the presence of common chemical solvents, a frequent problem in low-quality replacement parts that leads to the valve jamming in the open or closed position.

Compatibility and Installation Requirements

This valve is compatible with:

• DJI Agras T50 (Standard spraying system)
• DJI Agras T25 (Standard spraying system)

The installation must be performed with the spray system depressurized. It is necessary to check the integrity of the O-rings on the connected hoses before final tightening. Because it is an electrical component, the connector must be perfectly dry and clean to avoid electrical arcs or galvanic corrosion on the terminals.

Important Technical Guidelines and Considerations

To ensure the longevity of the PN 00000356 solenoid valve , it is imperative to perform a triple rinse of the spray system after each work shift. Dried chemical residues can form crystals that obstruct the movement of the internal piston.

In case of prolonged storage, it is recommended to apply a preservative fluid compatible with agricultural systems to prevent the internal seals from drying out. If the drone displays "Spraying system failure" or "Nozzle clogged" alerts, the solenoid should be one of the first items inspected for electrical continuity.
