Vannes à boisseau sphérique haute fréquence PDS

Présentation des produits

PDS high frequency ball valves are mainly used in PP/PE chemical plants .When the powdered product accumulates a certain amount in the reactor bed, the product discharge system (PDS) is automatically controlled to discharge the system. The PDS valve operates in a logical sequence to achieve product discharge, when any of the PDS systems A valve operation is not in place or faulty, the PDS system will not work properly. Due to the characteristics and requirements of the process technology, the PDS valve has extremely high operating life and demanding sealing level requirements.
