The new VMC series Pinch Sanitary Valves
Sanitary valves by AKO are based on a multi-functional modular system which enables a flexible exchange of the two types of body available – aluminium and stainless steel, and also a wide range of different collar caps/flange types/end connections – stainless steel and POM plastic.
Connection options are:
–Internal thread connection
–Flange connection
–Threaded Spigot
–Weld-on ends
–Tri-clamp connection
Alternatively, aseptic pipe connections, aseptic flange connections or aseptic clamp connections can be welded on according to DIN 11864 and DIN 11853.
Layout of the air operated VMC Sanitary Valves:
The layout of the VMC series of air operated pinch sanitary valves incorporates the heart of every pinch valve: the pinching rubber sleeve, a body and two end connections. The pinch sleeve is positioned in the centre of the sanitary valve body; both of its ends are pressed in by the end connections, thus forming a compact unit.
The different connection options and a range of elastomer qualities (pinch sleeves) such as abrasion-resistance natural rubber, natural rubber for foods, EPDM, EPDM for foods, nitrile, nitrile for food, hypalon, butyl, neoprene, silicon, and viton ensure that there is a very wide, virtually unlimited range of applications for the VMC series air operated pinch sanitary valves.
Air Sanitary Valves Benefits:
Some of the most important benefits of air operated sanitary valves are the flexible modular system which facilitates diverse connection options, 100% clear product flow and 100% sealing from the product flow. Even larger solid particles are surrounded by the pinch sleeve and are therefore tightly shut off.
In addition to having a compact and very lightweight construction, the air operated sanitary valve construction also offers customer friendly, simple assembly/dismantling of the sanitary valves. This makes it possible for every customer to replace the pinch sleeve on-site in just a few minutes without needing any special tools.
Furthermore, with the aid of the latest CAD software it was possible to achieve a weight reduction of up to 65% compared to previous series of sanitary valves.
Sanitary Valves Areas of Application:
Food/pharmaceuticals industry, sanitary waste disposal, steam cleaning, water treatment, chemical industry, air operated pump systems, pigment/granulate treatment, ceramic/glass/plastics industry, suction/metering systems, filling and weighing units, and ventilation systems are just some of the industrial/application areas in which our air operated sanitary valves from the VMC series can be used.
The maximum operating temperature of the VMC type sanitary valve is 120 degrees C, depending on the type of rubber elastomer. The maximum operating pressure (medium pressure) is 6 bar. The control pressure (closing pressure) of the sanitary valve should be 2 bar above the operating pressure.
The VMC series of air operated pinch sanitary valves is so far available in nominal diameters DN010-DN100, with sizes up to DN150 currently in production. AKO's sanitary valves meet all requirements of the Pressure Equipment Directive 97/23/EC.
Special conductive models with separate earthing are also available for use in explosive areas zones 0, 1, 2, 20, 21 & 22.
