Types and forms of electro-hydraulic proportional valves for construction machinery
Electro-hydraulic proportional valves include proportional flow valves, proportional pressure valves and proportional directional valves. The hydraulic operation characteristics of construction machinery are divided into two types of electro-hydraulic proportional valves in the form of structure: one is the spiral cartridge proportional valve and the other is the slide valve proportional valve
The screw cartridge proportional valve is a threaded electromagnetic proportional cartridge component fixed on the oil circuit assembly block. The screw cartridge valve has the characteristics of flexible application, pipe saving and low cost, and has been used more and more widely in construction machinery in recent years. Commonly used spiral cartridge type proportional valve has two, three, four and multi-pass forms, two-way proportional valve main proportional throttle valve, it often its components together to form a composite valve, the flow, pressure control; The three-way proportional valve is the main proportional pressure reducing valve, which is also the most used proportional valve in the mobile mechanical hydraulic system. It mainly operates the hydraulic multiway valve pilot oil circuit. The three-way proportional pressure reducing valve can replace the traditional manual pressure reducing pilot valve, which has more flexibility and higher control accuracy than the manual pilot valve
