Ball check valve with flanges AVK, NBR, PN10

Ball check valve with flanges AVK, NBR, PN10

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

• 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 steel in DN50 up to DN100, ductile iron from DN125 up to DN400 and cast aluminum in DN500. In DN600 the ball is of cast aluminum with PUR liner. The rubber hardness is optimised to prevent the ball from getting stuck in the seat.
• The ball is optionally available in polyurethane suitable for abrasive media and if different ball weights are necessary to prevent vibration and water hammer
• Compact design and low weight
• Bolts and nuts of stainless steel and body and cover of ductile iron with epoxy coating internally and externally according to AVK coating standard
