Generally, the working valve discs are configured in groups, and the inlet valve block has a built-in three-way pressure compensation bypass relief valve (logic element. When the multi-way valve stops operating and each valve is in the neutral position, the valve 6-12BAR) Bypass main oil flow. When a valve is working, the bypass port of the valve is reduced under the load pressure, and the required flow is provided according to the load pressure.
What are the types of multi-way valves, and what are their respective scopes of use?
1. Load sensing shuttle valve:
As long as it is used in mechanical design, machining, design software, mechanical engineer, equipment management, welding, hydraulic, casting, sealing, measurement, construction machinery, powder metallurgy, bearings, gears, pump valves, industrial automation
2. Safety relief valve:
Usually used for extreme protection of working mechanisms, such as luffing cylinders
3.Electromagnetic relief valve:
It is used for over-limit protection of working mechanism, such as torque limit of crane and three-circle protection.
4. Proportional pressure reducing valve:
Located on the opposite side of the pull lever of the working valve disc, it is a direct-acting proportional pressure reducing valve, which drives the spool valve to achieve proportional reversing.
