Question: How are domestic pneumatic cut-off valves? What’s a better price usually?
Domestically produced pneumatic cut-off valves are quite good. It’s hard to say anything about the price, as it depends on the valve’s diameter, material, as well as the configuration of the pneumatic actuator used
Guidelines for Selection: When selecting a valve, please provide the following information so that we can assist you in making the right choice: Valve name and model, Nominal diameter (mm), Nominal pressure (MPa), Inherent flow characteristic, Rated flow coefficient (Kv), Operating mode of the valve, Power source used for operation, Name of the medium and the pressure it operates under, Operating temperature and range, Materials used for the valve body, internal components, and packing, Accessories included, Connection method. For jacketed valves, it is necessary to specify the type and dimensions of the heat transfer medium interface; for low-temperature valves, it is important to indicate the insulation length and the connection method to the cryogenic tank. Explosion protection requirements, as well as any other special requirements
Choose the right valve based on the medium used – that is the wisest choice
What was said upstairs is correct – each manufacturer has its own flagship products and different focuses; it’s still the performance that matters
The domestic ones are quite average; those from Wu Zhong, Shanghai Factory 7, Chuanyi, and so on are generally in the tens of thousands range
There are many types of cut-off valves; I’m not sure which structure you have in mind. The quality of cut-off valves available in the domestic market varies, and their prices also differ. It’s a good idea to compare options from several different suppliers. Since the same product can yield different results under the same operating conditions, if the price is reasonable, it’s worth trying it out first.
