The earliest production mode in the field of valves, because the casting type does not have enough pressure, the valve produced by this process is easy to produce sand holes, leading to product leakage and a series of problems.
Choose according to the installation structure.The installation structure of pipeline system includes pipe thread, flange, clamp sleeve, welding, hose, etc.Therefore, the installation structure of the valve must be consistent with the installation structure of the pipeline, and the specifications should be in line with the size.
The valve connected by pipe thread is connected with the pipe thread of the pipe end. The internal thread can be a cylindrical pipe thread or a tapered pipe thread, and the external thread must be a tapered pipe thread
