  System integration into the field sprayer:

  Pneumatic supply required for ON/OFF control of each section

  • Automatic rate controller required
  • For OEM original fitment and retrofitting (fits all common nozzle bodies)
  • Replaces the standard section valves and hoses
  • Reduction in residual liquids, recirculation possible by mounting hoses in a ring line

Spray-Stop Direct Control Master

Multi line control

Master-Slave section control option capable of operating up to 8 standard Spray-Stops

Benefits for the end user:

  • Nozzle control is operated directly on the spray line
  • Fast and safe ON/OFF control reduces chance of over application
  • GPS section / individual nozzle control is possible (additional controllers required)
  • Pressure recirculation system possible
  • Instant liquid spray pressure at all nozzles when turning on (circulation system)
  • Minimal residual chemicals = less waste, reduced costs and safer environment


System integration into the field sprayer:

  • For modern field sprayers with pneumatic supply and electronical control
  • For OEM original fitment and retrofitting (fits all common nozzle bodies)
  • Replaces the standard section valves and hoses
  • Only one electrical line per section (Master-slave version)
  • Reduction in residual liquids, recirculation possible by mounting hoses in a ring line
  • No additional electro pneumatic valve bank required
  • Easy mounting of the pneumatic hoses
  • Cost-effective and flexible configuration of the sections easily achieved

Multi-Spray

Benefits for the end user:

  • Ideal for spray operators requiring different application rates / drop sizes / fast and easy nozzle change
  • Safe OFF control up to 15 bar spraying pressure
  • Fast and safe ON/OFF control reduces chance of over application
  • Selective manual or automatic nozzle switching is possible from the cab, depending on the electronic equipment
  • Pressure recirculation system possible
  • Minimal residual chemicals = less waste, reduced costs and safer environment

System integration into the field sprayer:

  • For OEM original fitment and retrofitting
  • Replaces the standard section valves and hoses
  • Reduction in residual liquids, recirculation possible by mounting hoses in a ring line
  • Infrastructure/facilities for pneumatic required for ON/OFF control

NEW 30 degree angled fitting option

Multi-Spray Direct control / master

Available for Twin and Quad bodies

Main benefits for the end user:

  • Nozzle control is operated directly on the spray line
  • GPS-controlled single nozzle or section control is possible with additional controllers
  • Instant liquid spray pressure at all nozzles when turning on (circulation system)
  • Pressure recirculation system possible
  • Minimal residual chemicals
  • Variable rate application / turn management possible with additional controller

altek ball valves

altek are continually updating the ball valves to deal with continually rising flow rates of modern sprayers. Accordingly, with the use of new material combinations developed in-house we vastly increased the wear resistance of the internal ball, which is able to withstand even highly abrasive substances.

In addition it is possible to adjust for wear by the use of adjustable seals to improve resistance.


Ball valves applied in sprayers are available for suction applications as well as for pressure application. They are available in different sizes and material strength.

altek offers for both suction and pressure ball valves in different sizes and available in both manual and electric operation.

 

 

Why choose altek?

  • altek have been manufacturing 5 way ball valves over 40 years
  • altek are the chosen supplier of 5 way ball valves to all the major European sprayer manufacturers

  • altek water test EVERY ball valve they produce before delivery
  • altek work closely with OEM's to improve and develop their products

 

Electrically-operated ball valves:

Extremely compact design

The same fixing points on the sprayer can be used for manual and electrical valves

Same motor drivce for 1¼“ and 2" ball valves (3" has larger motor)

Clockwise/anti-clockwise running optional

Switching time just 4 seconds for 360° rotation

 

 


Electrical Ball Valve 5-way 3“

The 3“ ball valve was introduced to fullfill the customer needs‘ of higher flow rates. 

The electrical 5 way 3“ ball valve hast he following specifications: 

  • high wear resistance ball to seals
  • ball bearing supported shaft
  • integrated safety operation
  • manufactured in liguid fertilizer proof anodiesed aluminium
  • optional: electric control with potentiometer


Manual ball valves:

altek 5 way ball valves are designed to:

•Simplify the operation of the sprayer

•Deal with Increasing flow rates 

Reduce pipework = less residual chemical

Easily incorporated into the altek plug-in-system, helping
to reduce assembly time!


Pressure Filter

altek International has been producing pumps, regulators and components for field sprayers since 1965. altek is well known to sprayer manufacturers around the world and has acquired an excellent reputation for its outstanding capacity for innovation, high quality standards and product durability. Its many years of experience and specialization in this ecologically and economically important niche has brought altek to the level of technological world leaders.

The efficient filtering of liquids is very important in the operation of the sprayer. altek has developed specific features to their pressure filters: The operators safety has been increased highly, since the filter element is removable to the top, during service. Undesirable contamination of chemicals to operator, environment and sprayer is avoided. The innovative concept of the pressure filter ensures, that the return flow from the regulator can be used for permanent filter rinsing. Extended working time of the filter between servicing is the result. Only the portion of liquid necessary for the boom spraying gets filtered. This increases the capacity of the filter.

Overview of features:

  • Available in 2 sizes: 260 l/min and AS40 connectors/ 500 l/min and AS50 connectors
  • Max. operating pressure up to 15 bar, pressure peaks up to 20 bar
  • Extended protection for operator, environment and sprayer, due to reduced risk of contamination during service is avoided
  • Innovative filter concept allows permanent filter cleaning
  • Smaller filter concept allows permanent filter cleaning
  • Smaller filter elements sizes are possible because filtering of the liquid for the spray boom only
  • Filter inserts sizes available in 30, 50, 80 and 100 mesh
