3112E笼式双座带平衡环调节阀
3112C
笼式双座调节阀
3112C Cage Double-seat Control Valve
3112E
笼式双座带平衡环调节阀
3112E Cage Double-seat Balanced-ring Control Valve
适用于常温高温高压差等苛刻工况下的流体控材，压降损失小，允许流通能力大，可调比大，阀芯采用压力平衡结构，且在套筒上增加平衡密封环结构，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.
