AVK THREADED BALL CHECK VALVE, PN 10
Ductile iron
Anthony Whittam
Network Water Specialist
Ball check valve with BSP threads for wastewater treatment and neutral liquids to max. 70° C
AVK ball check valves are self-cleaning and with full bore. The ball rotates during operation eliminating the risk of impurities getting stuck on the ball. The full 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 flanges and internal threads. They are delivered with NBR lined ball as standard and optionally with ball of polyurethane available in different weights.
