Economically unmatched and effective


EDS-Turbo Check Valves are used to protect compressed air systems against gas backflow. They have a compact design and are installed between 2 standard flanges. When pressure and speed drop, the low-mass plastic sealing body is immediately closed by the differential pressure of the system. This is because the system’s pressure is constantly present – from below the sealing body down to the annular bearing surface due to the pressure compensation holes, and is the case even when the valve is open.

The valve consists of only 4 components and is maintenance-free. Due to streamlined, nozzle-shaped cross sections, not smaller than 80% of the free pipe cross section, EDS valves feature the lowest pressure loss of their type.
The circular support of the sealing body is self-centering and gas-tight even at higher temperatures, as geometric errors and thermal expansion have no negative effects.

Due to the special manufacturing process for the sealing body, a tightness is achieved that is otherwise only usual for soft gaskets (leakage rate A according to DIN EN 12266-1:2003 P12).

The valves are also suitable for media containing dust and condensate, as hardly any deposits are possible due to the nozzle-shaped design.


  • Low pressure drop
  • Streamlined, nozzle-shaped cross sections
  • No smaller than 80 % of the free pipe cross section.
  • Maintenace-free
  • Gas tight
