Frequently Asked Questions
What are the company’s main products?
The company’s core product is the load-sensing proportional multi-way valve, a critical component of hydraulic control systems in construction machinery.
When using Comai’s PSL electro‑proportional valve, why does the oil temperature become exceptionally high (e.g., 110°C)?
In response to user feedback regarding the high-temperature issue with the PSL electro‑proportional valve, a common troubleshooting approach is to check whether the entire hydraulic system exhibits prolonged high‑pressure relief. Excessive oil temperature is typically indicative of a systemic problem rather than being caused solely by the valve itself.
