ATEC Compact Ball Valve


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


Suitable for High Pressure operations

The compact, stable construction with additional high pressure sealing edge enables the use in high pressure processes.

› HP-Sealcon (High Pressure) sealing edge for high pressure applications


Short installation length

Connecting the forwarding pipeline via threaded holes in the ball valve housing allows a very short length.

› Compact design

› Easy assembly in pipeline
