供应Parker德国制造电磁阀D1VW020BNJW

派克PARKER比例换向阀

PARKER派克比例换向阀通过调节输入阀内电磁铁的电压信号来控制工作阀阀芯的移动，使阀口尺寸发生改变，从而完成与输入电压成比例的压力、流量输出的控制，改阀具有集成的电子元件，主级的阀芯位置可调。

派克PARKER比例换向阀、派克PARKER比例方向控制阀D*1FH系列先导式比例换向阀被用于控制流量，该阀具有集成的电子元件，主级的阀芯位置可调，该阀共有10通径、16通径、25通径、32通径几种规格。应用于流量控制***和可实现流量调节，在快速/低速特性下的工作运行带有阀芯位置监控用于：压力机控制，动态位置调节和压力/流量闭环系统。 

特点： 

泄漏量小； 

高频响通油能力大； 

准确的故障状态诊断； 

零庶盖阀的机械式零点调节；
