平衡阀是一种特殊功能的阀门，阀门本身无特殊之处，只在于使用功能和场所有区别。 在某些行业中， 由于介质（各类可流动的物质）在管道或容器的各个部分存在较大的压力差或流量差，为减小或平衡该差值， 在相应的管道或容器之间安设阀门，用以调节两侧压力的相对平衡，或通过分流的方法达到流量的平衡， 该阀门就叫平衡阀 平衡阀是一种具有数字锁定特殊功能的调节型阀门， SUNCBCALAN SUNRDDDALAN SUN-353 CXCDXCN SUN-354 CXCDXAN SUNCXCDXFN SUNRDDALBN SUN-3560 UNK-50 SUN-3561 CXJA-XZN-DKN/S SUN-3562 CXJA-XZN-DKM/S SUNA101VSAE SUNA061VSA SUN-3565 CXOA-XCN-2bar（7-18A carity SUN-3566 CBEA-LHN/H90 SUN-3567 PPFB-LAN-BBP/M NG10 SUN-3568 PBDB-FNN SUN-3569 CKEB-XCN-BCV SUN-3575 CCCA-LHN1 SUN-3576 CCCA-LHA1 SUN-3577 NFDC-KCN SUN-3578 CWEK-LHN SUN-3579 DCEC-XWN SUN-3580 RPET-LWN SUN-3581 RVET-LAN SUN-3582 RSFC-LDN SUN-3583 COBA-XCN SUN-3584 LRFC-XFN SUN-3585 CXAD-XAN SUN-3586 RDBA-LAN 直流式溢流阀 SUN-3587 DAAA-MCV-223+760-223 SUN-3588 DKHR-8HV SUN-3589 FQCA-XAN-GCU(20LPM) SUN-3590 FDCB-LAN-DBY SUN-3591 CWCA-LHN-MBB SUN-3592 FDBA-LAN-GBX SUN-3593 PBDB-LAN-ECB SUN-3594 CKGD-XAN SUN-3595 CCEA-LIN SUN-3596 9JN9RPECLAN SUN-3597 SBY003 SUN-3598 SPN-HJ30-2A-POT-SS-5KD-11-G SUN-3599 SPN-HJ1M2-12/24 SUN-3600 CKEBXCN-YAV SUN-3601 EBY/S SUN-3602 CVEV-SAN SUN-3603 DAAL-MCN-224 SUN-3604 RVEA-KWN SUN-3605 RDHA-LBN SUN-3606 RVCA-LAN SUN-3607 CACA-LHN 配套密封组件T-11A SUN-3608 CBCA-LHN-XEV/S SUN-3609 NFDC-LAN-DBP/S SUN-3610 CKIB-LCN SUN-3611 RDFA-LAN-CKA/S SUN-3612 RPIC-LEN-IER/S SUN-3613 CBCA-LHN-ZNC/S SUN-3614 CBIA-LIM SUN-3615 CACA-LHN-EJV/S SUN-3616 CBCA-LHN-EJV/S SUN-3617 CBGA-LHN-ZNW/S SUN-3618 CXIE-XAN SUN-3619 RPEC-8WN SUN-3620 CKEB-XEV/PK SUN-3621 VXD2140-04F-5DI/ SUN-3622 JRD001 SUN-3623 JRD002 SUN-3624 XVO SUN-3625 YVY SUN-3626 OGZ7 PATRDDALCN SUN-3627 CBIA LIIN SUN-3628 RVEA LHN SUN-3629 QPAA-LAN SUN-3630 CV-16-XAN SUN-3631 CV-12-XAN SUN-3632 PN600S SUN-3635 EBY/S OG65 - A3 SUN-3636 EBY/S 1DY1 - A2 SUN-3637 WJA-LWV SUN-3638 P3JP-8DN SUN-3639 9F800S PMC#85J057 SUN-3640 PRDB-CSN-EBW SUN-3641 SXYY001 SUN-3642 RSJC-LAN SUN-3643 SCGA-LAN SUN-3644 CKIB-LAN SUN-3645 RVIA-LAN SUN-3646 PBDB-KQN SUN-3647 PBJP-8DN SUN-3648 CXDA-XCN-GDP SUN-3649 PRDB-CSN-EBP SUN-3650 RVEC-LBN SUN-3651 RPEC-LEN SUN-3652 RPGC-LEN CSS26K0819R SUN-3653 RADA-LCN SUN-3654 RDDALCV SUND SUN-3656 AG01 SUN-3657 单向阀CVID-XBN SUN-3658 PRFB-LBV SUN-3659 CXBA-XBV SUN-3660 NCCB-KAV SUN-3661 BKYOCU7-A2 PATDM7 SUN-3662 K25JSQ-H25 SUN-3663 PBHB-LAN-BKJIAG1-A2 SUN-3664 CWIA-LHN-QBY-1AG1-A2 SUN-3665 DB-B RPIC-LEN SUN-3666 NFDC-LAV(6,4 mm) SUN-3667 CXFA-XAN-DJ/S SUN-3668 RDDA-LAN-CBD SUN-3669 PPJB-LAV SUN-3670 PPFB-LNN SUN-3671 CBGG-LDN SUN-3672 CBGA-CAN 250BAR SUN-3673 YVR/S SUN-3674 ZCJ002 A/S OHEPSU SUN-3675 EZ002/S SUN-3676 RKVC25+ESH32 SUN-3677 WT 20.5有图，有网址 SUN-3678 FDFA-LAV
