53/35 BALL CHECK VALVE
Ball check valve with flanges 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.

Features
Ductile iron and fusion bonded epoxy coating guarantees resistance against corrosion and very long lifecycle
Self-cleaning construction, where the ball rotates during operation eliminating the risk of impurities getting stuck on the ball.
Full bore ensures low pressure loss and minimum back pressure.
Smooth bore eliminates the risk of deposits at the bottom.
NBR lined ball of aluminium in DN 50-100 and 500 and of cast iron in DN 125-400. The rubber hardness is optimised to prevent the ball from getting stuck in the seat. In DN 600 the ball is of aluminium with PUR liner.
The ball is optionally available in polyurethane suitable for abrasive media and if different ball weights are necessary to prevent vibration and water hammer.
