Importance of Valves in the Functionality of a Spray Unit
09 May 2023Spraying unit system management is of the utmost significance. In many applications, even modest pressure differences might result in potentially hazardous changes to the spray qualities. Moreover, precise management of the spray unit’s on/off cycle may be necessary. Using air atomising valvesand exerting control over the air in addition to the fluid will be necessary.
Several Kinds Of Spray Valves
The spray angle of most agricultural spray valves ranges from 65 to 120 degrees. Narrow spray angles create a more direct and penetrating spray; flat or wide-angle valves can be set closer to the target (crop or weed), spaced further apart on the boom, and offer overlapping coverage if necessary.
In spray operations, valves serve three purposes: flow rate control, droplet atomisation, and droplet dispersal. Each has a distinct function in pesticide/herbicide applications. Thus, it’s crucial to select the proper ones. There are several spray patterns, angles, forms, and sizes to pick from, depending on the sort of spray mechanism, application rate, and ground speed.
Fluid Regulator Valve
This pressure regulator may be adjusted between 0 and 60 PSI (0-4 bar). This will produce a fluid with a constant flow rate and spray qualities. With its four openings, the valve may accommodate a pressure gauge. They are constructed from sanitary food-grade polymers with fluid-contacting portions made of stainless steel, making them appropriate for food processing applications.
Fluid Solenoid Valve
These electrically operated valves enable fluid flow control with a speedy on/off response. They are available with two or three ports and in stainless steel (for hygienic applications) or brass (for non-hygienic applications).
Air Solenoid Valve
These electronically driven valves enable airflow control with a quick on/off response. They are available with two or three ports and in stainless steel (for hygienic applications) or brass (for non-hygienic applications). They are typically utilised with air atomising valves to fast switch on and off the air supply. Although air is far more sensitive than liquid, the air-actuated shut-off systems in our atomising airvalves may be cycled on and off up to three times per second when these valves are employed to regulate them. This provides for precise spraying control.
Air Regulator
The modular air regulator system consists of three functions. Initially, the air pressure will be regulated by the fundamental valves. This may be adjusted between 0 and 10 bars to maintain a constant airflow and pressure. This constancy is crucial in many air atomising spray systems, where minute fluctuations in air pressure may profoundly affect the resulting spray. In addition to pressure regulation, filtration and lubrication modules can be added to air regulation systems to make them comprehensive.These regulators are available in normal aluminium for non-hygienic systems and stainless steel for food, pharmaceutical, and other hygienic spraying applications.
Ball Valve
There is a basic selection of ball valves for controlling the flow in spraying systems. These manually controlled valves are available in several pipe diameters. They are available in brass and sanitary 316 stainless steel.
