Products Introduction

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, theproduct discharge system (PDS) is automatically controlled to discharge thesystem. The PDS valve operates in a logical sequence to achieve productdischarge, when any of the PDS systems A valve operation is not in place orfaulty, the PDS system will not work properly. Due to the characteristics andrequirements of the process technology, the PDS valve has extremely high operatinglife and demanding sealing level requirements.
