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.

GCJX series multi-way directional valve products
Uses and FeaturesGCJX series construction machinery with multi-way valve, the performance is completely equivalent to the German Rexroth SM12, SM18, SM25 multi-way valve. The valve body adopts a cast oil passage and a sheet structure, which has the advantages of small size, large flow, small pressure loss, high integration, small operating force, and compact structure. And according to different user requirements, any combination into a multi-way valve for different purposes. There are two control modes: manual and hydraulic control.This series of multi-way reversing valve is composed of inlet valve body (with safety valve), standard reversing valve body and return valve body. Can be single pump and multi pump oil supply, mainly suitable for small excavators, loaders, cranes, truck cranes, drilling rigs and other construction machinery, the valve can control up to 10 working institutions, to meet the requirements of the majority of users.
