力士乐比例流量阀BE6X-1X/315G24-8NZ4M比例流量阀由比例电磁铁和流量阀组合而成。 比例电磁铁与节流阀组合，称为比例节流阀，与调速阀组合称为比例调速阀，与单向调速阀组合称为比例单向调速阀。 比例调速阀的工作原理图。图中主阀为压力补偿调速阀，节流阀阀芯3与比例电磁铁1的推杆2相连。当有电信号输入时，节流阀阀芯3在比例电磁铁l的电磁力作用下，通过推杆2与阀芯左端的弹簧5相平衡，此时对应的节流口开度h为一定值，当输入不同信号电流时，便有不同的节流口开度。由于南通监控等差减压阀4保证节流阀进、出口压力差不变，所以通过对应的节流口开度的流量也恒定。若输入的信号电流是连续按比例地，或按一定程序改变，则电液比例调速阀所控制的流量也就连续地按比例地，或按一定程度改变，以实现对执行元件的速度调节DBETBEX-1X/315G24K0B5M DBETBEX-1X/250G24K31A1M DBETBEX-1X/80G24K31A1M DBETBEX-1X/180G24K31A1M DBETBEX-1X/315G24K31A1M DREB6X-1X/175MG24-25Z4V DRE6X-1X/175MG24-8NZ4M DRE6X-1X/75MG24-8NZ4M DRE6X-1X/310MG24-8NZ4M DRE6X-1X/245MG24-8NZ4M-6 DRUCKREGELVENTIL DRE6X-1X/175MG24-8NZ4M DRE6X-1X/75MG24-8NZ4M-7 DRUCKREGELVENTIL DREB6X-1X/310MG24-25Z4M DREB6X-1X/175MG24-25Z4M DREB6X-1X/75MG24-25Z4M DBE6X-1X/80G24-8NZ4M DBE6X-1X/180G24-8NZ4M DBE6X-1X/315G24-8NZ4M DBE6X-1X/315G24-25NZ4M DBE6X-1X/180G24-25NZ4M DBE6X-1X/80G24-25NZ4M DBETX-1X/180G24-25NZ4M-36 DBETX-1X/25G24-25NZ4M-36 DBETX-1X/350G24-25NZ4M DBETX-1X/50G24-8NZ4M DBETX-1X/250G24-25NZ4M DBETX-1X/50G24-25NZ4M DRUCKBEGR.VENTIL DBETX-1X/315G24-25NZ4M DBETX-1X/180G24-25NZ4M DBETX-1X/80G24-25NZ4M DBETX-1X/250G24-8NZ4M-34 DBETX-1X/250G24-8NZ4M-35 DBETX-1X/180G24-8NZ4M-34 DBETX-1X/250G24-25NZ4M-39 DBETFX-1X/80G24-27NZ4M
