Butterfly Valve Manufacturers & Supplier
Let’s first look at what a butterfly valve is? A butterfly valve is a quarter-turn rotational motion valve used to stop, regulate, or start fluid flow. It consists of a circular disc mounted on a rotating shaft. When fully closed, the disc blocks the passage of fluid; when open, it allows flow with minimal resistance. This simple, compact design makes butterfly valves ideal for applications requiring fast operation, space efficiency, and low-pressure drop.
When reliability, durability, and performance matter — TOT Valve delivers. As a leading butterfly valve manufacturer and supplier of industrial butterfly valves, we help you streamline fluid control across demanding applications with confidence.
Whether you’re operating in oil & gas, chemical processing, wastewater treatment, or slurry transport, our expertly engineered butterfly valves offer efficient shut-off, throttling, and flow regulation — without compromise.
Be careful when choosing a new valve supplier, the disappointment of poor quality can last much longer than the joy of a low price!
Advantage of Butterfly Valves
At TOT Valve, we specialize in manufacturing industrial grade butterfly valves tailored for demanding applications. Our valves are engineered to deliver tight shut-off, minimal pressure drop, and long-term reliability—even in corrosive, high-temperature, or high-pressure environments.

TOT Valves can provide a variety of ceramic material options according to your media and process conditions. Generally, the ceramic materials we provide include zirconium oxide (ZrO₂), aluminum oxide (Al₂O₃), silicon carbide (SiC), which have strong corrosion resistance, wear resistance and cost-effectiveness.
Ceramic vs. Metal Butterfly Valves: Which One Fits Your Application?
When it comes to harsh service conditions, the wear resistance, corrosion resistance, and service life of valves become critical. Both ceramic and metal butterfly valves have their strengths. Here’s a direct comparison to help you choose the best fit:
| Feature | Ceramic Butterfly Valve | Metal Butterfly Valve |
| Corrosion Resistance | Excellent — ideal for acids, alkalis, salts, and oxidizing media | Varies by metal type (e.g., stainless steel, alloy steel) |
| Wear Resistance | Superior — ideal for slurries, abrasive particles, and erosion-prone flows | Moderate — sealing surfaces may wear faster under abrasive conditions |
| Service Life | Long-lasting with minimal maintenance | Shorter life span, frequent maintenance needed |
| Temperature Tolerance | Depends on ceramic type; may limit at very high temps (>400°C) | Excellent — many metals withstand 800°C or more |
| Structural Strength | Brittle but strong — requires advanced composite engineering | Ductile and pressure-resistant |
| Cost Comparison | Higher upfront cost, but lower lifecycle cost | Lower initial cost, higher maintenance cost over time |
| Common Applications | Flue gas desulfurization, chemical processing, corrosive or slurry media | General water, HVAC, oil & gas, steam, food processing |
How to Choose the Right Butterfly Valve for Your System
