一种新型的液压流量控制阀,其主节流滑阀是由一用比例线圈控制的可变小孔的先导油路来进行位置控制的,它可以用现成的交流或直流电源获得的0～220毫安的低电流讯号提供高精度的比例流量控制(高达100加仑/分)。
A new type of hydraulic flow control valve whose main throttle valve is position controlled by a variable orifice pilot oil controlled by a proportional coil can be controlled by an existing AC or DC power supply of 0 ~ The 220mA low current signal provides high precision proportional flow control (up to 100 gallons / min).
