High-pressure rotary valves HDS
High pressure rotary valves are used for dosing, conveying and discharging bulk materials or other granulates and powders. The high pressure rotary valves are suitable for pressure differences up to 3.5 bar and are also used in pneumatic conveying systems. Design also according to Machinery Directive 2006/42/EC or ATEX Directive 2014/34/EU.
