Which brand of pneumatic control valve is good?

American ASCO, Danfoss, Dalhousie, Taiwan Province Chaco.

At present, domestic asco has built a production base in China, so basically, the quality of domestic assembly is slightly worse than that of Hilong and Nogren.

BIFOLD solenoid valves are not widely used in China at present, and the quality requirements are very strict. It's a high-end solenoid valve. With the adjustment of China's economic structure, from extensive to technical, I believe there will be a good market in China in the future.
