As a material, stainless steel is applicable in the manufacture of various types of valves. However, stainless steel valves for industrial use fall into some specific types of valves.
А stainless steel ball valve utilizes a hollow, spherical ball within its body to regulate the flow of the medium. A stem rotates the ball, aligning its bore to the flow of the fluid. Stainless steel ball valves in chemical processing are a crucial component, as they facilitate the opening, closing, and regulation of the medium's flow.
Stainless steel ball valves are ideal for fast opening and closing requirements within a chemical processing system. Ball valves enable rapid operation, making them suitable for applications where quick shut-off is necessary.
The primary use of a stainless-steel globe valve is to regulate the flow of the medium. Globe valve operation involves adjusting a movable disk connected to a stem using a wheel or a lever.
Stainless steel globe valves are ideal for systems that require precise control. They are common in power generation, water treatment, and chemical industries.
Apart from ball and globe valves, various other valve types, including stainless steel valves, are used in chemical plants. Each valve type targets to serve a specific function within a system. The other valve types used in chemical plants include:
A stainless steel gate valve's primary function is to start or stop the flow of the medium. It operates by raising or lowering a gate within its body, which allows or blocks the flow of the medium. Gate valves are not ideal for precise flow control. Today, you can also get a шаровой затвор из нержавеющей стали.
Stainless steel gate valves in chemical processing enable the complete shut-off of a line. They are ideal where there is no need for rapid shut-off or opening.
The design of butterfly valves makes them the most suitable for large-diameter pipes. They come in a compact design that compensates for weight and volume.
Butterfly valves are ideal for large-scale systems that utilize large-diameter pipes, such as those found in water treatment, oil and gas, and power generation.
Обратные клапаны utilize a flap or disc that opens and closes in response to the direction of flow. Their primary use is to prevent backflow.
Also known as non-return valves, check valves play a critical role in preventing backflow. They prevent pump-damaging backflows and maintain delivery pressure. Check valves are standard in water treatment, power generation, chemical processing, and gas pipelines.
Stainless steel's chemical resistance arises from its alloy composition. On exposure to oxygen, it reacts to form a passive chromium oxide surface.
The protective chromium oxide layer reduces corrosion and rust. It is a property that allows stainless steel valves to resist corrosion from chemical attacks, making them viable for use in chemical processing industries.
However, corrosion resistance in chemical processing varies depending on the stainless steel grades.
It's the most common type of stainless steel material used—austenitic stainless steel manufacturers corrosion-resistant valves, which exhibit non-magnetic properties. Popular grades include 304 and 316.
Both contain chromium and nickel. The 316 grade also incorporates molybdenum, which helps boost the material's corrosion resistance.
The grade is common in food and chemical processing. Austenitic stainless steel valves are standard components in plants due to their robustness and versatility.
It includes grade 430, which contains between 10% and 30% chromium and has a low carbon content. Ferritic steel is magnetic and also resistant to corrosion.
Ferritic stainless steel is less expensive than austenitic stainless steel. It has lower corrosion resistance, making it suitable for environments that require moderate corrosion resistance. It is the standard grade used in automotive exhaust systems.
Duplex stainless steel is a combination of austenitic and ferritic grades. It has superior strength and the capability to resist corrosion.
Some grades of duplex steel exhibit high resistance to localized corrosion, including pitting and crevice corrosion. Typical applications of duplex stainless steel valves are in harsh marine and petrochemical environments.
It is a stainless steel grade with a high carbon content that hardens upon heating. The 410 and 420 grades are ideal for their strength and corrosion resistance.
However, martensitic stainless steel is less resistant to corrosion than other stainless steel grades. The grade is ideal for applications that require higher strength and wear resistance, such as surgical instruments and cutlery.
