ZF Solenoid Valve 0501314770 / 0501316782 — 24V Transmission Pressure Regulator for 4WG200 & XCMG/LIUGONG Loaders
The ZF 0501314770 / 0501316782 is a 24V transmission solenoid valve (proportional pressure regulator) designed for ZF 4WG200, 4WG160, and 4WG310 powershift gearboxes. It regulates hydraulic pressure and flow within the transmission control circuit, enabling precise clutch engagement and smooth gear shifting in heavy-duty machinery. This valve is widely used in XCMG wheel loaders (ZL50G, ZL50GN, ZL50GV), LIUGONG loaders (LG958, LG956, CLG856, CLG888), and Doosan/Komatsu MEGA series equipment. Operating pressure range is 0.8–8.3 bar. Cross-reference numbers include SP123103, SA8320-01170, and 832001170. The valve is a direct-fit replacement for worn or failed original units, restoring proper transmission response and preventing harsh shifting or loss of drive.
