Rotary valves: The right one for every application!

Rotary valves are important components in conveying technology for feeding, discharging or dosing fine-grained and dusty 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 screw conveyors, are relieved and the entire system runs more consistently with less maintenance.

Our portfolio of rotary valves covers every need

Neue JÄGER Maschinenbau is a manufacturer specialising in the development and sale of rotary valves. Every customer requirement can be solved! The highest quality requirements are already applied during product development and design. Our rotary valves are used as top products for the controlled discharge and dosing of powdery and granular materials. And this worldwide! The main areas of application are in the food industry as well as in the areas of plastics production and processing, the pharmaceutical and chemical industries and the mineral processing industry.

Whether pneumatic rotary valves with rotation monitoring, over- or underpressure-tight versions or special designs to customer specifications: we develop and manufacture every rotary valve to the highest technical standard. Please do not hesitate to contact us!

What can our rotary valves be used for?

All rotary valves from Neue JÄGER Maschinenbau can be used for dosing, conveying and discharging bulk materials and as a protective system or device in potentially explosive areas.

Therefore rotary valves from Neue JÄGER Maschinenbau

Our construction kit includes a wide and varied range of variants and combination options in different designs and materials, with different sealing systems and drive concepts:

  • Directly flange-mounted geared motor
  • With and without torque support
  • Motor lantern
  • Base plate
  • Chain drive
  • Large variety of cellular wheels for specific applications

In addition to a wide range of modern rotary valves, which are currently manufactured in sizes 100 to 1000, 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 26 February 2014 is also available for our construction kit.

Each New JÄGER Rotary Valve can be used as a machine in the sense of the Machinery Directive 2006/42/EC and as a type-tested device of Category I 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.

Neue JÄGER thus offers all plant manufacturers or operators of plants a complete range of ATEX rotary valves for the implementation of EU Directive 2014/34/EU or ATEX 137. Each individual rotary valve is pressure shock resistant up to 25 bar and ignition proof up to 10 bar.
