Wherever a medium needs to flow in just one direction within a pipeline system and return flow needs to be prevented, WEH® check valves fulfil this function with absolute reliability.
WEH® check valves for medium pressure applications are available in two versions:
- with o-ring seaingl for special tightness requirements, especially for gaseous media
- with metal ball sealing for frequent pressure changes and lower tightness requirements, especially for liquid media.
