What are the advantages of stainless steel globe valves? What is the ...
Stainless steel globe valve is a kind of globe valve. The specific stainless steel materials are CF8 (304), CF3 (304L), CF8M (316), CF3M (316L). Different materials are selected, which can be applied to water, steam, and oil. , Nitric acid, acetic acid, oxidizing media, urea and other media. Stainless steel globe valves are divided into manual stainless steel globe valves, pneumatic stainless steel globe valves, and electric stainless steel globe valves. Connection methods include general globe valve threaded stainless steel globe valve, angle stainless steel globe valve, three-way stainless steel globe valve, DC stainless steel globe valve, heat preservation stainless steel globe valve, etc. The most obvious advantage is: in the opening and closing process, due to The friction between the disc and the sealing surface of the valve body is smaller than that of the gate valve, so it is wear-resistant.

Stainless steel globe valve holding point:
(1) The structure is simpler than the gate valve, and it is more convenient to manufacture and maintain.
(2) The sealing surface is not easy to wear and scratch, and the sealing performance is good. There is no relative sliding between the valve disc and the valve body sealing surface when opening and closing, so the wear and scratches are not serious, the sealing performance is good, and the service life is long.
(3) When opening and closing, the disc stroke is small, so the height of the shut-off valve is smaller than that of the gate valve, but the structure length is longer than that of the gate valve.
(4) The opening and closing moment is large, and the opening and closing is more laborious, the headmaster of the opening and closing time.
(5) The fluid resistance is large, because the medium passage in the valve body is relatively tortuous, the fluid resistance is large, and the power consumption is large.
(6) When the nominal pressure of the medium flow direction PN≤16MPa, the downstream flow is generally adopted, and the medium flows upward from below the valve flap; when the nominal pressure PN≥20MPa, the reverse flow is generally adopted, and the medium flows downward from the top of the valve flap. In order to increase the seal performance. When in use, the shut-off valve medium can only flow in one direction and cannot change the direction of flow.
(7) The valve disc is often eroded when fully opened.
As an indispensable part of the valve industry, the stop valve plays a pivotal role in the industrial development of our country. From the beginning of the development of the early liberation of the stainless steel stop valve to today, the production and manufacturing model has been continuously improved but facing the foreign WJ41H bellows There is still a gap in the shut-off valve. Foreign products have a strong grasp of the valve market in my country. Because their products are indeed excellent, my country's stainless steel shut-off valve industry is facing a serious market crisis. The crisis has greatly stimulated domestic shut-off valve manufacturers and promoted the formation of a This is a competitive mode of competition, enterprises need to step up their independent research and development, actively explore new markets, expand business channels, and lay a solid foundation for my country's valve industry to go global.

1. Superior Corrosion Resistance
Stainless steel contains elements like chromium and nickel, which form a protective oxide layer on the valve's surface. This layer shields the valve from the corrosive effects of various chemicals, acids, and moisture. In environments such as chemical plants, marine settings, and food processing facilities, stainless steel valves can effectively resist corrosion, ensuring long-term reliability and reducing maintenance costs.
2. High Strength and Durability
These valves possess excellent mechanical strength. They can endure high pressures and significant mechanical stresses without deforming or failing. The robust nature of stainless steel makes valves suitable for demanding applications in industries like oil and gas, power generation, and heavy manufacturing. Their durability also means they have a longer lifespan, providing a cost-effective solution in the long run.
3. Hygienic and Easy to Clean
Stainless steel is a hygienic material. Its smooth surface does not harbor bacteria, making it an ideal choice for applications in the food, beverage, and pharmaceutical industries. It complies with strict hygiene standards and is easy to clean and sterilize, ensuring product safety and quality.
4. Aesthetic Appeal
Stainless steel valves offer a sleek and modern appearance. Their polished or brushed finish gives them a professional and elegant look, making them suitable for use in visible areas, such as architectural and interior design projects where both functionality and aesthetics are important.
5. Versatile Applications
With various designs and configurations available, stainless steel valves can be used for a diverse range of applications. They can handle different types of fluids, including gases, liquids, and slurries. Whether it's controlling the flow of water in a water treatment plant or regulating the passage of hazardous chemicals in a chemical refinery, stainless steel valves can meet the specific requirements.
In conclusion, stainless steel valves are a reliable, durable, and versatile choice for various industries, offering numerous benefits in terms of performance and aesthetics.
