3112E籠式雙座帶平衡環調節閥
3112C
籠式雙座調節閥
3112C Cage Double-seat Control Valve
3112E
籠式雙座帶平衡環調節閥
3112E Cage Double-seat Balanced-ring Control Valve
適用于常溫高溫高壓差等苛刻工況下的流體控材，壓降損失小，允許流通能力大，可調比大，閥芯采用壓力平衡結構，且在套筒上增加平衡密封環結構，密封效果好。
Apply interesting such harsh working conditions of high temperature and high pressure fluid control material, small pressure drop loss, allow the flow capacity is big, adjustable ratio is big, the pressure balance valve core structure, and increase his balance on the sleeve sealing ring structure, good sealing effect.
