Advantages

ATEC Ball Valve Type_DG

Cavity free

The usual cavity between ball and housing in non- cavity free ball valves give cause for disturbance because residual products can crystallize, polymerize and so affect the function.

› Clean, non- false product

› No sediments of expensive products in the ball valve housing

Spring loaded ball sealing system

Approximately same torque at different temperatures This request can only be achieved by ball valves with a spring-loaded sealing system. Different heat expansion of metallic and synthetic material cause high torques by non spring-loaded sealing systems so that the valve can block and does not open or close anymore. Longer lifetime through spring- loaded sealing system. Spring-loaded cavity free ball valves achieve this improvement in a variety of processes. At abrasion, the spring-loaded sealing system guarantees a controlled compression of the ball sealing so that longer sealing life and leak-tightness can be realized

› Longer Lifetime

› Same torque at different temperatures
