派克减压阀R4VW31A1P1 减压阀是通过调节，将进口压力减至某一需要的出口压力，并依靠介质本身的能量，使出口压力自动保持稳定的阀门。从流体力学的观点看，减压阀是一个局部阻力可以变化的节流元件，即通过改变节流面积，使流速及流体的动能改变，造成不同的压力损失，从而达到减压的目的。然后依靠控制与调节系统的调节，使阀后压力的波动与弹簧力相平衡，使阀后压力在一定的误差范围内保持恒定优势系列为D1VW， D3VW ，D31 ，D41 ，D91 ，PV140 ，PV016 ，PV063 ，PV270 ，PV046 ，FM3DD ，CPOM ，VMY ，产品为换向阀、减压阀、泵。 D1FBE01HK0VKW3 D1VW030HVKW C10DFC123E25/0U R4VW31A1P17 D1VW008KNJDL D111VW020B2NJW3A D91VW009C2NJW3A GFG2PKC3.2V-10 R5VA1 R4VP1G0QA1 R6VG0QB1P25 D89V001C1N91X712 D31FPE01DC4NS70 D1FPB60HH9NB00 D31DW004E4NJDLJ5 R5VG0QA1152 D1VW002CNJDL D1VW011CVTW D99V001C1N C10DEC101E63/0U3000 R6VB1 C050WAN CP063S07S14N C063CAN D111FBB31LC4NF00 D3W010ENJW D1FEE01HC9NB03 AXEHK D41FBE01FC5NJW0 R4VA1104 D91FBB32HC4VG00 D4LB004C5N D4LB020D5N D4LB001C5N D3HW20HNJEU30XB671 D1VW002ENJW4N D41FBB32FC5VJW0 D1MW020DVTWW D1MW083HVTWW D41VW020D5VTWW D91VW030D2NJW C025F17S999999N D3W001CNJWS7 D1FPE50CH9NE00 D1DW020HNJW4DC06X575 RE32E17W1SN1XWM D1VW026HNJWXG168 D3FPE50YB9NB70Q80 D1VW030BNJWT D91FEZ02HC2NK7L D4S10-9G1346CAB1 C10DEC101E50/0U3000 R4VA1 D4S10-9C2146DBG0QB1 R5VG0QA1152 D3FBE01ME0NKW3 D81VW011C5NYW D81VW020B2NJWTI5N D81VW002E2NJWTI5N R5VA1 CP063C07S14N D41VW011C6NYW3C D41VW002C6NJW3B D4L009N5N D1DW020BNJWI5NC06X575 D41FPZ61FB2NB7L D1VW004FNGW D41FBB32FC1VF00 D31DW004C4VJWI6N D3FPE02PC9VS00 C016G35SN D81FHB32E5VS00 D111FHB32H5VS00 D1MW026BNSWWXG170 R4UW30A1 D3DW014CNJWC08 D89V001A3N91X712 C032CAN D3FPE02PC9NE50 D41VW002F2NJAXG172 D41VW020B2NJAXG172 R5UG0QA1 D1VW009FNJWT D1VW001CNTWT D41VW009C6NJW3B D1FBE50CC0VF00 R4VG0QA1031P25 D3DL030DN4K D3W002CNKWS7 R5VG0QA1152 AXC3F006009 D41FEZ31FC4NS0L D4S03-3A514409G0QB1 R4V10-535W0A1P13 D1FBE01FC0NF00XG216 D81VW009K2NGWWI2N D4S06-92N3A2B1053 D4S06-9C23C6DBG0QB1 D3W020DVGW D41VW002C6NJWI6N D1MW004CNYWW R5V10-495P2PM4MAA1 D31DW020B4NJWTI5N D31DW004K4NJWTI4N SVPN1080E16N1PBF R4VG0QA1031P17 AK-D1VWSJWW91 PRPM3AA35KV D91FBZ32HC1NKWL D91VW004C4VYW D41FHB32B1NS00
