The Background of AKO AKO is a family run company with the head office based in Germany, and subsidiaries based in the UK and France, with distributors of AKO products in countries all over the world. AKO is proud to have been in business for over 30 years now, manufacturing and supplying their Pinch Valve…
The powders being passed through the fully open bore of a Pinch Valve can either be gravity fed, pushed along using compressed air, or sucked through using a vacuum system. Whichever conveying method is used, Pinch Valves guarantee a free flow of product because of the nominal passage of practically all diameters. The Pinch Valve is non-clogging, and in most cases wear resistant. Other advantages include it’s light weight, simple installation and lightening fast opening/closing times.
Valves for Sack Filling Machinery Sack or bag filling machines are expertly designed with the precision control of a pinch valve. The pinch valve opens and closes extremely quickly, ensuring the media such as powders, granules, food, pet food, horticultural seed and flakes are shut off at the exact required time. The fully open, true…
Air fluidisers are small and simple cone shaped components that solve bulk dry powder and granular material flow problems, acting as a flow aid. Bridging, caking, compacting and rat-holing are common reoccurring problems in large vessels including silos, hoppers and bins. A simple solution for solving this issue is to install air fluidisers around the vessel, which give off a gentle vibration using low volume directional airflow and aeration.
AKO UK are supplying their VMP plastic Pinch Valve in DN25 (product code VMP025-03XK-72) into a concrete slurry application, which is used as a fail safe option. The concrete slurry with very fine aggregates in size 0.3-1mm is used for robotic concrete printing.
The world’s first commercial 3D concrete printing robot is currently in design production, with the aim to be used on site to produce a variety of elements including cladding panels.
AKO Pinch Valves are also a lot more light weight because they no longer have heavy cast iron flanges. Instead they now come in aluminium with a choice of bushing material if required, such as mild steel or stainless steel. The rubber sleeves inside the AKO Pinch Valves are also improved with extra walls,…
Aerators (also known as aerator pads, airbrators, and vibrating cones) are a simple component made up of a rubber cone or ‘mushroom’ shaped body, with a threaded screw connection, washer and fixing nut. These small but important devices are used for aeration, to simply get dry powders, granules and pellets to move.
A Pinch Valve is an economical piece of equipment that works like a tap. It has an on/off function, to shut off, allow or control the flow of any media passing through it. The Pinch Valve is made up of three parts:
More and more engineers and plant workers are opting for the Pinch Valve when fitting or replacing abrasion resistant valves. The Pinch Valve is a highly robust type of valve that is extremely reliable, with a very good elasticity. One of the main positive factors of this type of abrasion resistant valve is that it has lightening fast opening/closing times, ensuring a quick shutoff.
Having the simplest valve design, pinch valves comprise of a flexible elastomer body that obstructs the flow of media through the pinching mechanism of the rubber sleeve, which is the main working element. The rubber sleeve is pinched closed either by the application of fluid pressure or mechanically in the body. It is squeezed at the valve’s mid-section, clamping or pinching its walls together to tightly close the flow path.
