Abrasion resistant valve types with a smaller bore size such as 25mm have been victoriously used in a water pumping system. The abrasion resistant valves are used on a landfill site using air pumps operating at about 4.5 bar where it is required to pump to another area when the tank fills up and the valve closes.
One abrasion resistant valve is often tested on a trial basis and when it is proven to be working satisfactory, more valves are installed on various other plants.
Abrasion resistant valves are also used in other applications where water is used on road sweeping machinery. After recently developing a recycled water system where contaminated water is coarsely filtered and directed down to a suction pick-up system, the valve has worked wonders for the job.
Furthermore, abrasion resistant valves with a true bore and low maintenance are proving to be the ideal solution for handling and controlling the flow of media in the following areas of industry:
- The manufacture of gelatin for soft gel capsules
- Sand foundries & sand blasting machinery
- Mineral powder
- Crop spraying
- Aqueous solution of Aluminium Chlorohydrate
- Wet shot blasting cabinets for water
- Water based china clay slurry for Filtration System
- Iron oxide powder
- Environmentally friendly biochemicals that can replace oil-based products.
- Powder coating plants
- Animal remians
- Plastic pellets
- Powdered Sulphuric Acid & Ethyl Acetate
- Sodium Carbonate powder
- Concrete on-off dispensing
An Abrasion Resistant Valve for Pharmaceutical Uses
Aside from large industrial applications such as those mentioned above, abrasion resistant valves are also being used by pharmaceutical companies manufacturing small medical tablets. One particular company is using these valves with stainless steel tri-clamp end connections. For this application, the valve will be kept normally closed and will then open for a number of seconds to pass tablets through by gravity falling pressure.
Abrasion Resistant Valves for Confectionery Production
Abrasion resistant valves are now installed on a UK plant producing sweets after a successful trial period. The particular application is used with a vacuum, which pumps at 280/260 millibar. The abrasion resistant valve (with an aluminium body and stainless steel G3″ end connections), is normally closed, and has approx 220 cycles per hour. The plant runs about 14 hours a day, 5 days a week.
Another valve on the same plant has special stainless steel weld-on connections which means the user can weld on any specific fittings required.
