Assembly instruction

Advantages

ATEC Sampling Ball Valve Typ_PR

Low sump area

By the use of an angled stem design and the direct mounting to the vessel bottom flange, the ATEC bottom outlet ball valve ensures flush fitting with the vessel inner bottom.

› Minimal accumulation of product between ball valve ball and vessel inner bottom

› Improvement of product mixing in stirrer vessel

› Reduction of efflorescence and product agglomeration

› Avoiding false samples

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 housingn

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
