Integral multi-way directional valve LT-M45-6Y-6T
Uses and FeaturesLT-M45 series multi-way directional valve, is my company to absorb and digest foreign advanced multi-way directional valve technology based on the development of advanced performance products. Mainly used in engineering machinery, mining machinery, coal machinery, agricultural machinery in the hydraulic system.The valve is an integral structure, small size, high pressure, large flow, one to six to choose from, can return oil, can also be used across the bridge, is the ideal product of the host localization. Performance parametersPath（mm）Nominal pressure（Mpa）nominal flow（L/min）Allowable back pressure（Mpa）1031.5453
Drilling rig integrated main valve XZJ-A
Uses and FeaturesXZJ combined multi-way directional valve is a new generation of tunnel drilling rig valves independently developed by our company. The valve has comprehensive functions and simple operation, and has a qualitative improvement over the multi-way valve of the previous generation tunnel drilling rig. The valve has three operating handle rods, only two of which are used for daily operation, and the third one is used for unloading drill pipe, testing and other working conditions. The valve even misoperation will not bring danger, high safety. Performance parametersPath（mm）Nominal pressure（Mpa）nominal flow（L/min）Allowable back pressure（Mpa）2531.52002
Drilling rig integrated main valve LTZJ-20-10-03B
Uses and FeaturesLTZJ-20/10 series combined multi-way reversing valve is a new generation of products designed and developed by our company for the domestic full hydraulic tunnel drilling rig. The valve inherits the advantages of our company's original tunnel drilling rig combined multi-way reversing valve, and has made great innovation on the basis of our company's original tunnel drilling rig multi-way reversing valve. Compared with the original combined multi-way directional valve for tunnel drilling rig, LTZJ-20/10 series combined multi-way directional valve further reduces the volume, reduces the installation space of hydraulic valve on the host, optimizes the matching characteristics of multi-way valve and host system, optimizes the design of micro-control of each actuator, and changes the auxiliary valve of the original control part to cartridge type, which can make the control points of each mechanism clearer, for the host hydraulic system adjustment provides a convenient. Performance parametersPath（mm）Nominal pressure（Mpa）nominal flow（L/min）Allowable back pressure（Mpa）2031.51502
Drilling rig integrated main valve ZMZJ-00
Uses and FeaturesZMZJ combined multi-way directional valve is my company for the domestic full hydraulic tunnel drilling rig design and development of products. The valve is the first for the full hydraulic tunnel drilling rig hydraulic system integration products. The valve can optimize the complex pipeline in the original hydraulic system, and the host structure is more compact. The valve has compact structure, good fretting performance, low pressure loss, high efficiency of the host system, can realize centralized control, and is more convenient to operate. The valve for the mine under the operation to do the optimization design, in order to eliminate the influence of the working condition environment on the hydraulic valve, our company will ZMZJ-00 designed as a protective combination of multi-way valve, can make the working condition of the environment on the hydraulic system cleanliness to a minimum. ZMZJ-00 multi-way directional valve has obtained the national invention patent. Performance parametersPath（mm）Nominal pressure（Mpa）nominal flow（L/min）Allowable back pressure（Mpa）2531.52502
