The company needs to purchase a batch of pneumatic valves, and due to budget constraints, domestic brands have to be chosen. Does anyone have any recommendations for reliable brands that have been used before? Thank you! ! !

Domestic products also come in various quality levels; there are truly countless options, just as the person above said... How much budget do you have in mind for a single valve? What caliber, what material, what actuator, what type of positioner – list all the requirements so that the experts at Haichuan can analyze them for you.

If you want to get good quality items at a lower cost, you need to be discerning, compare the specifications of different products, and carefully assess their quality. My brother, in the workshop there are two lathes side by side: one is from a large, well-known manufacturer, and the other is from a small, unknown manufacturer. Once, our village asked him to process a batch of small parts. I went to his workshop and saw that with the same tool and at the same speed, the precision of the parts manufactured on the lathe from the large, well-known manufacturer was significantly better than that of the parts made on the lathe from the small, unknown manufacturer. . . These are not the 1980s; with a bit of courage and some money, one can open a factory and get by. Now that the market is mature, it’s very difficult for manufacturers to succeed if they can’t produce products of reliable quality. These small, lesser-known factories are often run by skilled craftsmen; many of their owners are actually former employees of larger companies. You should by no means underestimate the technical capabilities and quality standards of these small factories. It’s not uncommon for their products to be both inexpensive and of high quality, offering great value for money. . .

If domestic options are chosen properly, they can also be very useful. Let me mention a few brands that we find to be quite good: Chuanyi, Wuzhong, Zhejiang Sanchang, and Taiwan’s Jindian (highly recommended)

The poster should provide some parameters – the quality of domestically produced products varies greatly. Xiaoyao and Zhugé are both good choices; there’s no need to buy the most expensive ones – just select those that are best suited for one’s own needs. In the past, I worked in a workshop, doing tasks such as machining, drilling, and sandblasting. At that time, there were no CNC or fully automated machines, so we had to calculate the necessary values manually before starting work. We also had to fabricate and assemble valves, including the position switches themselves; the same was true for pneumatic actuators. Each brand has its own advantages, and small factories also have their strengths in terms of precision and efficiency.
