This listing is for a used rotary valve — also referred to as a rotary airlock or cellular wheel valve — a type of metering and flow-control device widely used in bulk solids handling, pneumatic conveying, and powder processing applications to regulate the discharge of granular or powdery materials between process stages while maintaining pressure differentials. DMN Machinefabriek is a Dutch manufacturer with a long-standing specialisation in rotary valves and related bulk material handling equipment, serving industries such as food, feed, chemical, and plastics processing.
This particular unit is the AL-175 DAI MZC in the Easy Clean configuration, manufactured in 2012 and located in Barneveld, Netherlands. It carries CE marking and is constructed throughout in stainless steel grade 1.4401 (AISI 316), making it suitable for hygienic and corrosion-sensitive applications.
The rotor measures 175 mm in diameter and 200 mm in width, and is fitted with eight pockets, each measuring 80 × 80 mm, giving a displacement of 5.5 litres per revolution. The rotor turns at 14 rpm. Both the inlet and outlet are 175 mm in diameter, each served by flanges with a 300 mm face dimension. The installation height of the valve body is 350 mm, with an overall height of 0.50 m and a floor footprint of 0.95 × 0.65 m.
The unit is equipped with air-purged seals, which help prevent product ingress into the bearing and seal areas — a feature particularly valued in fine powder and hygienic process environments. Drive is provided by a 0.55 kW motor rated at 220–242 / 380–420 V and 1,380 rpm. The serial number is 122625.
