目前,ZFS型多路换向阀在工程、矿山、起重运输和专用设备上被广泛应用。但该阀横向安装尺寸过大,而且是底座安装,进出油口朝上。在需要多个工作机构集中操作的机器设备上,要用高低不同的弯头把进出油管引出,要占用很大的空间位置,使安装和操作极为不便。 At present, ZFS-type multi-way valve in engineering, mining, transportation and special equipment is widely used. However, the transverse installation of the valve size is too large, but also the base installation, out of the oil port up. Need to work in multiple institutions centralized operation of the equipment, the use of different elbow into the oil pipe leads to take up a lot of space, so that the installation and operation is extremely inconvenient.
