Long-term use of residual oil backwash filter programmable valve packing
Thread Content
As shown in the picture, the residual oil hydrogenation raw material backwash filter programmable valve uses a double-acting cylinder-driven ball valve. Due to frequent movements, packing leakage often occurs. I would like to ask you all, do you have a good maintenance strategy for long-term use?
Does your valve have ISO 15848-1 certification?
