Agricultural Equipment Agricultural Slurry Sprayers

The PW-KZ1 intelligent spray control system is designed for precision and quantitative spraying of herbicides, insecticides and micro-fertilizers with boom/rod sprayers. It is widely used on crops such as cotton, corn, soybean, wheat, rice, potato and a variety of medicinal and forage plants.

Key components include: an integrated valve system (pressure sensors, flow sensors, proportional valves, pressure reduction and master valves, regulator packs, filters, fittings and bolts), the main line, GPS receiver, power cord, display, display stand and operating instructions.

The valve body shell uses nylon anti-aging plastic and spool components are made from stainless steel and other anti-corrosive materials to provide strong corrosion resistance and durability in agricultural chemical environments.

Precision is achieved through proportional valves, flow and pressure sensors and GPS guidance. The control electronics modulate flow per section/boom to maintain target application rates and use GPS positioning to manage section switching and reduce overlap.

The system is designed to match common working pressures and joint specifications of most spray booms and rod sprayers. Confirm physical fittings, voltage requirements and control signal compatibility with your equipment or consult the supplier to verify fitment.

Avoid spraying in rain or immediately after rain, do not operate under high wind or very high temperatures, and do not operate at high ground speeds. Follow local label recommendations for chemicals and respect weather limits to ensure effective application.

Wear appropriate personal protective equipment per the pesticide/fertilizer label and local regulations: chemical-resistant gloves, eye protection, long sleeves, long pants, and respirator when required. Ensure valves and electrical connections are correctly insulated to avoid short circuits.

Mount the GPS receiver with a clear view of the sky (roof or high bracket) and secure the display on the supplied stand within easy view of the operator. Connect the GPS and display to the main harness and power supply per the provided wiring diagram in the operating instructions.

Check that the master valve is open, filters are clean, and regulator packs are set correctly. Inspect for clogs in nozzles or lines, verify pump operation, and ensure pressure sensors and flow sensors are connected and functioning. If using section control, confirm the proportional valves and wiring are intact.

Ensure the GPS antenna has unobstructed sky view and is correctly connected. Reboot the display and power cycle the system. Check cables and waterproof connections. If problems persist, consult the manual for error codes and contact technical support with the error details.

Clean filters and strainers after each major use or daily when working with dirty liquids. Flush tanks, lines and valves after each chemical change or at the end of the day. Inspect seals, hoses and electrical connections regularly and replace worn parts as needed.

Drain and thoroughly clean the system, remove and dry filters, protect electrical connectors with waterproof caps, and store in a dry, sheltered place away from freezing temperatures. If freezing is possible, fully drain and use appropriate antifreeze or remove sensitive components per the manual.

Yes — common spare parts and consumables such as filters, nozzles, seals and valve components are typically available. Contact your supplier or the manufacturer with model and part numbers to order replacements.

The product includes operating instructions that cover installation, wiring, operation, calibration and maintenance. Suppliers often provide additional technical support and can offer training or commissioning services upon request.

Warranty terms and technical support vary by supplier and region. Contact the seller or manufacturer for specific warranty coverage, service plans and authorized service centers. Keep purchase documentation and serial numbers handy when requesting support.
