意大利阿托斯叠加式减压阀HG主要作用 减压阀的作用原理是靠阀内流道对水流的局部阻力降低水压，水压降的范围由连接阀瓣的薄膜或活塞两侧的进出口水压差自动调节。定比减压原理是利用阀体中浮动活塞的水压比控制，进出口端减压比与进出口侧活塞面积比成反比。这种减压阀工作平稳无振动；阀体内无弹簧，故无弹簧锈蚀、金属疲劳失效之虑；密封性能良好不渗漏，因而既减动压（水流动时）又减静压（流量为0时）；特别是在减压的同时不影响水流量。 HC HCM 20 HF-0611-IX 24DC 10 (L05) HG HGPE HG HG HGV 23 HG HG HG HG HM HMV 40 HM HM HMV 40 HM HM HM HM HMV 40 HM HM HMV HMP HMPV 22 HMP HMPR 22 /BT HMP HMP HMPV 22 HMP HMP HMP HMPPE HMP HMPPE HMP HMP HMPPE HMP HMU HP1351A10AN HQ-012 HQ HQBT HQPE HQ-012/G 54 HQ-013/G 54 HQ-014 52 HQ-022 52 HQPE HQ-022/U 10 HQ-023 52 HQ-024 HQ-024 52 HR-004 30 HR-011 11 HR-011/2 HR HR-011/4 HR HR-012 HR HRPE HRWG HR HR HRPE HR HR HR HR HS HZGO-A HZGO-A HZMO-A JO-DL-10-2/NC-X 24DC 10 JO-DL-4-2/NC/FI-X 24DC JO-DL-4-2/NC/FI-X 24DC 30 JO-DL-4-2/NC-X 24DC 30 JO-DL-4-2/NO-X 24DC 30 JO-DL-6-2/NC-X 24DC 10 JPC JPG JPG JPGV 30 JPQ-212 JPQ JPR-212 16 JPR-312 16 KC KG KG KGV 21 KG KIT组装PVPY-LZQZ-4045泵用阀组) KIT组装PVPY-LZQZ-5071用阀组) KIT-E-SW-PS-TERS KM KM KM KMPE KMV 50 KM KMPE KMV 50 /BT KM KM KM KMV 50 KM KM KQ KQPE KQ-022 KQ KQPE KQ-022/G 54 KQ-023 KR-004 35 KR KR-012 KR-012 35 KR KRPE KR KR KR KR-012/D 35 KR KRPE KR KR-013/D 35 KR-016 KZGO-A KZGO-A LASA LIDA-32433/FI/NC 10 LIDBH1C-4-IX 24DC 30的底座 LIMHA-4/350/V-IX 24DC 32 LIMHCX 24DC 31 LIMHZX 24DC LIMM LIMM LIMM LIMM-5/100/V 31 LIMM LIMM LIMZO-AX06A LIMZO-A LIMZO-A-5/315/P 30 LIQZO-L-1002L4 70 LIQZO-LE-252L4 60 LIQZO-LE-252L4/Q 61 LIQZO-LE-322L4/Q 50 LIQZO-LE-502L4 50 LIQZO-LE-502L4 80 LIQZO-LES-PS-322L4 61 LIQZO-LES-PS-802L4/I LIQZO-TE-322L4/I 71 LIQZO-TE-322L4/I 73 LIQZO-TE-402L4/I 71 LIQZO-TE-402L4/I 72 LIQZO-TE-502L4/Q 60 LIRA LIRZO-AE LMHM的配件) LM-06/50(HM-011/50的配件) LU-O3A-UX 24DC 27 MAP-040 MAP-040 20 MAP-080 20 MAP-080/E 20 MAP-160 20 MAP-320 MAP-320 20 MD44-S1/50-24DC MDID-SAC MDID-S3S/55-110AC MDID-TA/50-24DC MDID-TA/55-110AC ME-K-PID MZOAF(RZMO-A的电磁铁+线圈) OA/M 220(防爆线圈) PFEDU 20 PFEDU 20 PFE-31028 PFEDT 20 PFEDV 20 PFEDT 20 PFEDU 20 PFEDU 20 /WG PFE-31044 PFEDT 20 PFEDV 20 PFE-41056 PFE-41056 PFE-41056 PFEDU 20 PFEDW 20 PFEDT 20 PFEDU PFE-51110
