American standard valves: 3 inches, 150 pounds rating, 1500 yuan each. Butterfly valves: 20 inches, 150 pounds rating, 12500 yuan each. Is it cheap? Expensive? Ordinary manufacturers
It doesn’t state what the material is, what the maximum temperature is, nor whether the lining of the butterfly valve is made of rubber or PTFE
Specific data is missing, such as whether an actuator is included, the valve body material, the valve disc material, temperature, etc. Valves are generally custom-made and not highly versatile.
It’s not possible to determine the exact price here; specific parameters are missing. To purchase a valve, a model number is required, or the application conditions should be provided for selection.
At the very least, please mention the valve material, drive type, and connection method
It would be best to send a screenshot of the valve’s specification sheet.
The correct way to answer is to provide the price of some ordinary valve, or simply give an example of the price for a certain type of valve. Constantly saying that something is missing is nothing but a superficial response; it’s not meaningful at all

American standard valves, 3 inches, 150 pounds rating; the price is 1,500 yuan per unit. The price of ordinary hand valves is roughly the same, while those of slightly higher quality (such as those from CNNC or NEWAY) cost over 2,000 yuan.
