Most of today's standard valves are used in devices with American standards, or in special plumbing systems. What are the characteristics of a typical valve? The main features of gate and globe valves in this type of valve are described. If the national standard valve is the main pipeline opening and closing component currently in use, then the American standard valve is the main control opening and closing component for a kind of imported equipment. As a kind of valve device forged by American standard, its use is quite frequent at present. Both the gate valve and the reverse check valve are more prominent valves. Compared with other valves, the feature of gate valves is the truncation. The valve is somewhat similar to a small gate and plays a similar role. It is a device that blocks the medium and prevents the medium from flowing through. As one of the mainstream types of valves, gate valves play a more powerful role in blocking than globe valves compared to American standard cut-off valves, with greater truncation strength and better effect. This is also the current advantage of gate valves and globe valves.
