The Globe Valve is a widely used shut-off and regulating valve in industrial and civil pipeline systems. Its core function is to precisely control the "on-off" and "flow regulation" of media (liquids, gases, steam), and it is particularly suitable for scenarios that require fine control of flow or pressure. Its structural design focuses on "unidirectional sealing" and "adjustability", and is widely used in fields such as chemical engineering, petroleum, HVAC, water supply and drainage, etc
The structure of the stop valve determines its unique usage characteristics, which are fundamentally different from gate valves, ball valves and other types of valves.
1.It has both cutting and regulating functions, with high regulating accuracy
2. It has high flow resistance and high energy consumption
3. One-way sealing is required, and the flow direction must be strictly distinguished during installation
4. The opening and closing stroke is short and the operation is convenient
5. It has stable sealing performance and good wear resistance
6. It has diverse structural forms and is suitable for different scenarios
According to the valve cavity structure, stop valves can be classified into three mainstream types to meet different installation and working conditions requirements:
A. Straight-through stop valve: The valve cavity is in A "Z shape", allowing the medium to flow in a turn and achieving the maximum flow resistance. It is suitable for scenarios with sufficient installation space and low resistance requirements (such as civil water supply and drainage).
B. Angle stop valve: The valve cavity is in an "L shape", with the inlet and outlet perpendicular (90° Angle), suitable for installation at pipe turns (such as boiler steam pipes), and the flow resistance is slightly lower than that of the straight-through type.
C. Y-type stop valve: The valve cavity is in a "Y" shape, providing a smoother flow path for the medium and the least flow resistance. It is suitable for high-pressure, high-flow or scenarios where pressure loss needs to be reduced (such as high-pressure process pipelines in the chemical industry).
