Crane car valve 5DP20GL-LG-A

Uses and Features5DP20GL-5 multi-way directional valve is mainly for the domestic 8-12 tons of full hydraulic truck crane on the car control valve replacement and design of new products. The performance of the product has reached the international level of similar products. The valve is a casting oil duct chip structure, with small size, large flow, low pressure loss, the most prominent feature is the use of series oil, the real sense of the linkage, greatly improve the work efficiency.The double-pump confluence and five-position double-speed technology are used in the hoist working condition, which realizes the low speed of heavy load and high speed of light load, thus being more safe and reliable. The valve is mainly used for crane lifting, luffing, telescopic, slewing mechanism. 5DP20GL-5 multi-way valve has won the national invention patent. Performance parametersPath(mm)Nominal pressure(Mpa)nominal flow(L/min)Allowable back pressure(Mpa)2031.51852
