Rotary valve for pneumatic conveying (round flange)
max. 295 m³/h, max. 1.5 bar | MDS series
Zeppelin Silos & Systems
The MDS rotary feeders are mainly used for the discharge (dosing) of pellets and powders from silos and hoppers. Furthermore they serve as feeding devices in pneumatic dilute phase conveying systems with a differential pressure up to 1.5 bar (g).
Design characteristics
* optimized inlet and outlet cross section for gentle product feeding combined with optimized filling degrees
* leakage gas nozzle integrated into housing
* solid temperature range from -10 to +60°C and ambient temperatures from -10 to +40°C for standard design; other temperature ranges according to customers' requirements
* minimum leakage gas volume due to optimum execution of gaps and 12 chamber rotor
* circular inlet and outlet flange - no transition pieces required
* mounting devices for gear motor, junction box and if necessary for solenoid valves and supporting construction directly at housing
* externally located ball bearings with lifetime lubrication; material outlet opening between shaft sealing rings and bearing
* labyrinth sealing ring, for powdery products with purge gas device, preventing material flow into the sealing area
* free shaft end of rotor visible, enabling a visual control of the sense of rotation and rotor
* speed chain drive with adjustable chain tension roller
* closed chain guard made of aluminum\'
* EC conformity declaration according to ATEX regulations 94/9EG
