Series 903 metal seated silent check valves are designed to prevent back flow in high-temperature range pumping applications. The valve element movement is controlled via a central guide where a centrally mounted spring together with the short movement aids the quick closing that is essential in reducing shock associated with valve closure. The pumped media can be water, glycol or other clean, neutral liquids.
Series 41 SWING
CHECK VALVE

AVK series 41 swing check valves come with both metal and resilient seats. Installed in pumping applications to prevent back flow they can be used for drinking water as well as waste water. The disc is connected to the shaft via a flexible bush that allows disc and valve seat to adjust exactly. All interior parts are stainless steel or coated with drinking water approved epoxy or EPDM. The series 41 valves are available with either closed bushings or protruding shaft end where a lever with a weight or a spring can be fitted to mitigate pressure surges.

AVK FLANGED
BALL CHECK VALVE
法蘭球形止回閥
AVK ball check valves are self-cleaning and full-bore. The ball rotates during operation, eliminating the risk of impurities getting stuck on the ball. The complete and smooth bore ensures full flow with low-pressure loss and eliminates the risk of deposits at the bottom. AVK ball check valves are available with angles and internal threads. They are delivered with an NBR-lined ball as standard, and optionally with a urethane-only ball available in different weights.
