Application
DRSX Sanitary version Rotary Valves are used as volumetric feeders for
dry free-flowing powder materials for pneumatic conveying systems and
as dischargers or metering valves below silos and hoppers in the food
and pharmaceutical industries and in all industrial fields where high
sanitary standards are required. All material contact surfaces are in
accordance with the requirements to avoid contamination and degradation.
Easy removable rotor for fast cleaning is standard.
Size
Available in four standard sizes: 6, 8, 10, 12.
Pressure range
Up to 1bar differential pressure.
Temperature
Handled material temperature up to 120°C.
Construction materials
• Housing and end plates
stainless steel AISI316
• Rotor
Stainless steel AISI316
• Surface treatments
All material contact surfaces are polished (Ra=0,8)
• Packing
PTFE
• End plate O-ring
Silicone for food industry
Rotor
8 (standard), 10 or 12 vanes open end, fabricated
construction and bevelled edge.
Drive
Direct with worm gearmotor.
Features
1 Out-board mounted sealed ball bearings, maintenance free
The ball bearings are provided with high quality grease. No re-greasing
required.
External bearings prevent the material from entering into the bearing.
2 Packing glands or air purge seal
The shaft seal is with PTFE packing glands
Labyrinth ring and air purge connection on request; no deposit or dirt
around the seal.
3 Stainless steel end plates
Silicone End plate O-ring for food industry.
4 Sanitary version 8 (standard), 10 or 12 vanes open end rotor, fabricated
construction and bevelled edge
This special rotor reduces the friction surface between the rotor and
end plates and avoids contamination and degradation of the handled material.
5 Valves with flanges in accordance with DIN2501 PN10 o ANSI150
Large air vent openings for special operating conditions.
6 Rotor-drive shaft coupling.
7 Clamps
No tools required.
