Drilling rig integrated main valve YZJ-JBD-A

Uses and FeaturesYZJ-00 tunnel drilling rig multi-way valve is my company's independent research and development of the third generation of tunnel drilling rig with valve. The valve has comprehensive functions and simple operation. The clamp and chuck are in a linked state under various working conditions, and the efficiency is obviously improved. On the basis of adding drill pipe after, the original function of adding drill pipe before is created, which is convenient to switch. The built-in balance valve solves the problem of power head sliding down, and the product structure is compact and easy to install. Performance parametersPath（mm）Nominal pressure（Mpa）nominal flow（L/min）Allowable back pressure（Mpa）2531.52502

Load Sensitive Multiway Reversing Valve QFZMG15H-5-SANY

Uses and FeaturesQFZMG15H type full load sensitive multi-way directional valve is one of the latest products developed and produced by our company. Its excellent full-load feedback function can realize the system load sensing follow-up control, reduce the load of the pump, reduce power consumption and system heating, so that the control accuracy of the construction machinery can be improved in an all-round way, and the energy loss is minimized. It can be called a high-precision control energy-saving product.QFZMG15H type full load sensitive multi-way directional valve, with excellent "valve pressure compensation" function, each working oil port can be according to the requirements of the host actuator, to provide the corresponding flow, and to ensure that the working speed of the actuator is not affected by load changes, and has excellent micro-performance.The QFZMG15H type full load sensitive multi-way directional valve is operated in various ways. With manual, hydraulic proportional, electro-hydraulic proportional control of a variety of control methods.The development of QFZMG15H-type full-load sensitive multi-way directional valve adapts to the development trend of domestic construction machinery industry, and its performance has reached the technical level of M4-15-type multi-way directional valve produced by Rexroth abroad. It is an ideal product for the localization of host hydraulic system. Performance parametersPath（mm）Nominal pressure（Mpa）nominal flow（L/min）Allowable back pressure（Mpa）Pilot control pressure（Mpa）153815020.5～2.4
