No. Question Standard Answer
Q1 Which excavators match 24V swing proportional solenoid valve 116-3526 1163526? This flange-mounted rotary proportional valve fits E320B, E330B, E320C, E325B, E330C medium and large hydraulic excavators.
Q2 How does this solenoid control excavator swing rotation speed? It receives ECU PWM signal to generate proportional electromagnetic force, adjust the opening of swing control oil circuit, steplessly change the flow into swing motor to control rotary speed smoothly.
Q3 What abnormal rotary faults will occur when this solenoid is damaged? Unsmooth swing action, out-of-control rotation speed, slow rotary response, swing jitter during composite operation and continuous high hydraulic oil temperature.
Q4 Is full disassembly of the multi-way valve required during replacement? No, external flange fixed design, only remove four fixing bolts and disconnect the wire plug, no need to split the internal main valve body.
Q5 What anti-wear and high-temperature design adapts to long-term mining work? The whole spool undergoes ion nitriding hardening treatment, matched double high temperature HNBR sealing rings and fully sealed two-pin waterproof plug to resist hydraulic oil, dust and continuous high heat.
Q6 Are 116-3526 and 1163526 interchangeable part numbers? Yes, these two codes represent the same complete swing proportional solenoid assembly and can be replaced mutually.
Q7 How to quickly detect coil damage before installation? Use a multimeter to measure coil resistance, normal range 14–14.8 ohms; infinite resistance means open circuit, resistance below 10 ohms indicates internal short circuit and cannot be installed.
