Looking for domestic mid-range valve brands

We use those from Zigong No. 2 Medium-Pressure Valve Factory (not meant as advertising, btw)

What industry are you in? We work in the field of industrial fire protection, and valves have always been a problem for us. We’ve tried several different brands of valves, but they’re all more or less the same

Imported valves also have advantages in terms of BFE; I’ve sent you details via private message

There are too many; brands such as Yi, Zigong, Chuanyi, Wuzhong, Newway, Keway, and Chuanghe are all excellent among China’s second-tier and above brands

Actually, I don’t think there are any clear standards for determining which brands belong to the mid-range and which ones are high-end. It’s not the case that high-end valves will never break, while mid-range or low-end valves will definitely break; the quality of a valve depends on several factors, 1: Is the right model selected? (There are actually some operating conditions for which valves of this structural type cannot be used, yet you chose this one anyway. If it breaks down, whose responsibility will it be?) As soon as a valve owned by the client breaks, the first assumption is that the quality is poor; meanwhile, the valve manufacturer might think that the problem is caused by the conditions at the installation site or improper operation, and that’s how disputes arise between them. ) 2. Is the sales approach professional? A professional salesperson is one who helps customers solve their problems, rather than someone who just tries to sell you valves. 3. The attitude of the valve manufacturers: In many projects, bids are won on the basis of low prices; to secure these contracts, companies are forced to cut costs. Some manufacturers produce products without any regard for quality standards, which results in various problems once the valves arrive at the installation site. If a valve leaks, it should definitely not be used in the future – if such problems occur right after arrival at the site, it’s likely that the valves weren’t tested for pressure resistance before leaving the factory. 4. The installation schedule needs to be planned carefully. In some cases, it’s not advisable to start installing valves too early. I’ve encountered situations where valves were manufactured two years ago, installed after more than a year, and have been in use for almost a year. When these valves were installed too early, and moreover they were located in outdoor areas in the northeast, with no protection whatsoever, more than 10 solenoid valves burned out right from the start of operation. The solenoids were original ASCO products, not imitations or fake ones. So whose fault is this problem? Many times, some things just can’t be clarified! Try to have it retrieved and installed a few months before driving, as even the best products have a shelf life; the longer you wait, the greater the likelihood of damage. I’ve said a bit too much today~~~~~~~

This question is a bit too broad – there are far more than ten thousand valve manufacturers in China. What’s important is to take into account various factors such as the requirements for on-site use, product quality standards, after-sales service, and procurement budget. Our town is a hub for the valve industry (Oubei), and the production of valves takes place here in large quantities. There is actually a lot of choice available, and it depends on how you decide to proceed; P
