Rotary valves are important components in conveying technology for feeding, discharging or dosing fine-grained and powdery products or granulates. In order to relieve the bulk material of the silo pressure, rotary valves are often installed under silos. Downstream elements in the conveyor chain, such as tube chain or trough chain conveyors or screws, are relieved and the entire system runs more consistently with less maintenance.
Neue JÄGER is a manufacturer specialized in the development and distribution of rotary valves. Already during product development and design, the highest quality requirements are taken as a basis. Our rotary valves are used for the controlled discharge and dosing of powdery and granular materials. The main areas of application are found in the food industry as well as in the areas of plastics production and processing, the pharmaceutical and chemical industry and the mineral processing industry.
In addition to a wide range of modern rotary valves, which are currently manufactured in 9 different sizes, our construction kit also has an EC type examination certificate from DEKRA EXAM (notified body No. 0158) in accordance with Directive 2014/34/EU of the EUROPEAN PARLIAMENT AND OF THE COUNCIL of February 26, 2014.
Each of our rotary valves can be used as a machine in the sense of the Machinery Directive 2006/42/EC, as a type-tested Category I device or as an autonomous protective system for explosion decoupling. Category 1D, 2D or 3D devices are available for use in zones 20, 21 or 22.
Thus, Neue JÄGER offers all plant manufacturers or operators of plants a complete range of ATEX rotary valves for the implementation of the EU Directive 2014/34/EU or ATEX 137.
