No. Question Standard Answer
Q1 Which medium excavators adopt proportional solenoid valve 627-2304? This flow limiting flange proportional solenoid is specially manufactured for 320GC and 330GC medium construction excavator hydraulic pump regulator manifold block.
Q2 What energy-saving flow limiting function does this valve realize? It dynamically limits main pump hydraulic flow according to working load, cut redundant hydraulic output and realize low fuel consumption operation for long-hour construction.
Q3 What abnormal machine performance will occur if the original solenoid fails? Unstable digging strength, delayed boom and stick movement, fluctuating pump pressure and obvious continuous rise of hydraulic oil temperature.
Q4 Is full disassembly of hydraulic main pump required to replace this flange solenoid? No, external flange bolt fixing design allows single-piece quick replacement without splitting the whole pump assembly.
Q5 What anti-interference design guarantees stable signal in harsh construction environment? Thickened multi-core oil-resistant wire and fully sealed two-pin plug resist long-term vibration, dust and high temperature interference effectively.
Q6 Can single sample be supplied for field hydraulic performance test before bulk purchase? Yes, single-piece sample order is supported to check fitting condition and flow limiting control effect on excavator on site.
