Product Details

1.1 Features

Good anti-corrosion: each valve body shell is made of nylon anti-aging plastic, and the valve core components are made of anti-corrosion materials such as stainless steel;

Strong adaptability: the working pressure and joint specifications are matched with most boom sprayers, which facilitates the installation of various boom sprayers;

Strong stability: The cable connection joint adopts waterproof treatment to prevent short circuit, open circuit, unstable circuit and other circuit failures.


1.2 Purpose and scope of application

The LC-19A series of intelligent spray control systems are mainly used in conjunction with boom sprayers for precise and quantitative spraying of chemical herbicides, pesticides or micro-fertilizers. It is widely used in plant protection operations of cotton, corn, soybean, wheat, rice, potato and other crops, Chinese herbal medicine, pasture and other plants, and other agronomic spraying operations.

Brief introduction of intelligent spray control system function

The intelligent spray control system has three working states:

In the automatic state, the spraying volume per hectare (the spray volume) set by the user is controlled to control the spraying, running faster and spraying more, running slow and spraying less, stopping and not spraying, and the spraying volume per unit area is balanced.

In the manual state, it can be sprayed under normal pressure, just like a traditional sprayer

In the closed state, the system cuts off the flow to the nozzle, so that the liquid medicine returns to the medicine tank, which plays a role of stirring

The system monitors the driving speed, flow, and pressure in real time and counts the total work area, total flow, total distance, and total time.



The water pump, filter, regulator, pressure relief valve, and piping system on the sprayer need to be provided by the sprayer manufacturer.
