Stainless Steel Butterfly Valves
TOT Valves to Meet Your Industrial Needs
A stainless steel butterfly valve is a quarter-turn valve used to control the flow of liquids, gases or slurries in a pipeline. The valve consists of a circular disc (or “butterfly”) that rotates within the pipe to regulate the flow. Made from high-quality stainless steel, our valves offer excellent corrosion resistance, durability and the ability to withstand extreme temperatures, making them ideal for a variety of industrial applications.
When you specify a valve for your system, you can’t compromise on durability, compatibility or lifecycle value. That’s where our stainless steel butterfly valves come in – designed for tough conditions, well-made and trusted by industries that demand zero failure.
Whether you’re shopping for a 2 inch stainless steel butterfly valve for a compact loop or a 6 inch stainless steel butterfly valve for a high-volume process line, our product line will meet your performance needs and ensure your operations run consistently.
If you are looking for a stainless steel butterfly valve manufacturer that can provide stable quality, competitive prices and professional services as a long-term partner, TOT will wholeheartedly support your business.
Contact us now, let us help you optimize your pipeline efficiency and reduce operational downtime today.
Be careful when choosing a new valve supplier, the disappointment of poor quality can last much longer than the joy of a low price!
Stainless Butterfly Valves Built to Withstand Harsh Environments
Why Stainless Steel is Your Best Material Choice?
Not all valves are created equal – and not all environments can stand up to them. When it comes to corrosion, temperature fluctuations or sanitary control, stainless steel outperforms traditional materials like cast iron or plastic. Here’s why stainless steel butterfly valves are your first choice:
- Excellent Corrosion Resistance: Suitable for chemical, seawater and industrial wastewater systems
- Thermal Stability: Withstands high temperature fluctuations without deformation
- Hygienic and Easy to Clean: A must-have for stainless steel sanitary butterfly valves installed in the food, beverage and pharmaceutical industries
- Structural Integrity: High strength-to-weight ratio – less wear, fewer replacements

FAQ
Body: Made of stainless steel (typically SS 304 or SS 316), which provides superior strength and resistance to corrosion.
Disc: The central component that rotates to control the flow. The disc is also made from stainless steel.
Stem: Connects the disc to the actuator or manual handle, allowing for rotation of the valve.
Seat: The seal between the disc and the valve body, often made from materials like PTFE or EPDM, depending on the application.
Actuator: A mechanism that enables automatic or manual operation of the valve. Actuators can be pneumatic, electric, or manual.
The valve operates by turning a lever, gear, or actuator to rotate the disc inside the pipe. When the valve is fully open, the disc is positioned parallel to the flow path, allowing maximum flow. When the valve is closed, the disc rotates 90 degrees to block the flow. The position of the disc directly controls the flow of fluid through the valve.
Corrosion Resistance: Stainless steel is highly resistant to corrosion, making it perfect for use in aggressive environments such as chemical plants, wastewater treatment, and marine applications.
Lightweight & Compact: Compared to other valve types, butterfly valves are generally lighter and more compact, making them easier to install in tight spaces.
Cost-Effective: They offer excellent performance at a relatively low cost, particularly in large-diameter pipes.
Versatility: Stainless steel butterfly valves can be used for a wide range of applications, from water systems to harsh industrial chemicals, due to the adaptability of the material and design.
Water Treatment: Regulating the flow of water or wastewater.
Chemical Processing: Controlling the flow of chemicals in pipelines.
HVAC Systems: Managing airflow and pressure in heating, ventilation, and air conditioning systems.
Food & Beverage: Ensuring sanitary flow control for food processing lines.
Marine & Offshore: Providing reliable performance in seawater systems.
Wafer-style: Compact and cost-effective, this valve type fits between two flanges and is often used in space-constrained environments.
Lug-style: Has threaded holes on both sides of the valve, allowing for easy isolation of the valve without removing other components.
Flanged: Used for larger systems, with flanged ends that are bolted directly into the pipeline.
Sanitary: Designed for applications where cleanliness and hygiene are critical, such as in the food and pharmaceutical industries.
