KSB globe valves are suitable for applications that require precise flow control
Date: 2025-09-02Read: 16
KSB globe valve is a widely used valve in fluid control systems, whose main function is to control the flow of fluid in pipelines. As a shut-off valve, K can accurately cut off or regulate fluid flow, and is therefore commonly used in pipeline systems for various media such as liquids and gases. The working principle is based on the principle of fluid flow control. By sealing the valve disc and seat inside the valve body, the flow and stop of fluid are controlled. Specifically, when the valve rotates, the valve stem drives the valve disc to move up and down, adjusting the gap between the valve seat and the disc to control the fluid flow rate. Generally, a straight through structure is adopted, with the valve stem perpendicular to the direction of the fluid, which can ensure unobstructed fluid flow and achieve precise adjustment between fully open and fully closed.
KSB globe valveThe main characteristics are:
1. Efficient flow control: It can accurately adjust the flow rate when the valve is fully or partially open, suitable for situations that require precise flow control.
2. Good sealing performance: Due to the use of high-quality sealing materials and precise processing technology, it has good sealing performance and can effectively prevent medium leakage.
3. Corrosion resistance: Different materials such as stainless steel, cast steel, etc. can be used according to requirements, which can work for a long time in highly corrosive environments.
4. Simple structure, easy maintenance: The structural design is relatively simple, easy to maintain, and has a long service life.
5. Wide applicability: Suitable for controlling various fluids such as water, oil, gas, etc., widely used in multiple industries such as power, petrochemical, metallurgy, chemical, water supply and drainage.
Structural composition:
1. Valve body: The valve body is the main load-bearing part, responsible for bearing the pressure of the fluid inside the pipeline. Valve bodies are generally made of materials such as cast steel, carbon steel, stainless steel, etc., which have good pressure resistance and corrosion resistance.
2. Valve disc: The valve disc is a key component that controls fluid flow, and achieves fluid switching operation through its contact or separation with the valve seat.
3. Valve seat: The valve seat is the part that comes into sealing contact with the valve disc, and has good wear resistance and corrosion resistance, which can ensure good sealing effect.
4. Valve stem: The valve stem is used to connect the valve disc and the valve disc, and the opening degree of the valve disc is adjusted by rotating the valve stem.
5. Packing box: The packing box is used to prevent medium leakage at the valve stem. Ensure the sealing performance of the valve stem through the sealing effect of the packing.
6. Handwheel: The handwheel is a component used for manually operating the shut-off valve, and the operator adjusts the valve opening by rotating the handwheel.
Application areas of KSB globe valve:
1. Power industry: Used in power generation equipment such as thermal power plants and nuclear power plants to control the flow of fluids such as cooling water, steam, and chemicals, ensuring the safe operation of the equipment.
2. Petrochemical industry: Used in petrochemical equipment to regulate and control the flow of raw materials and finished oil, ensuring the smooth progress of petrochemical processes.
3. Metallurgical industry: In steel production, it is used to regulate the flow of high-temperature and high-pressure fluids to ensure the stability of the smelting process.
4. Water supply and drainage industry: Used for flow regulation and system control in water supply networks and sewage treatment plants, it is a key equipment to ensure smooth water treatment processes.
5. Food and pharmaceutical industry: In the process of food and pharmaceutical production, precise control of fluids during product processing can be ensured to meet hygiene requirements.
