Yes, Carilovalves definitely offers ball valves specifically engineered for under-tank applications in chemical plants. Zhejiang Carilo Valve Co., Ltd., established in 2000 and operating from their manufacturing base in Wenzhou, Zhejiang Province, has developed a comprehensive range of industrial ball valves that meet the demanding requirements of chemical processing environments where under-tank valve installations are critical for fluid control, safety, and operational efficiency.
Understanding Under-Tank Valve Requirements in Chemical Plants
Under-tank valve applications in chemical plants present unique challenges that demand specialized engineering solutions. These valves typically handle corrosive chemicals, high-pressure transfer systems, and require maintenance accessibility in confined spaces. Chemical plant operators need valves that can withstand aggressive media while providing reliable isolation and control capabilities.
Carilovalves has addressed these challenges through targeted research and development, creating ball valve configurations optimized for tank bottom service, drainage systems, and chemical transfer lines. Their engineering team understands that under-tank applications require specific considerations including:
- Corrosion resistance against specific chemical compositions
- Sealing integrity under varying temperature conditions
- Minimal dead leg design to prevent product accumulation
- Emergency shutdown capabilities for hazardous material handling
- Compatibility with automated control systems
Technical Specifications for Chemical Plant Applications
Carilovalves provides detailed technical data sheets for their chemical plant ball valves, allowing engineering teams to specify the correct configurations for their specific applications. The following table outlines the key performance parameters:

|---|---|---|
| Pressure Rating | PN16-PN40 | Up to PN100 |
| Temperature Range | -20°C to +180°C | -50°C to +300°C |
| Size Range | DN15 to DN200 | DN15 to DN600 |
| Body Materials | SS304, SS316 | SS316L, Hastelloy, PTFE lining |
| Seat Materials | PTFE, RPTFE | PEEK, CTFE, Graphite |
The company’sball valve designs incorporate features specifically beneficial for under-tank installations. The floating ball design ensures consistent sealing even when dealing with particles or debris common in chemical tank bottoms. For applications requiring fire-safe certification, Carilovalves offers API 607 compliant designs with graphite-based secondary seals.
Material Selection for Chemical Compatibility
Chemical plant applications require careful material selection to ensure long-term reliability. Carilovalves provides multiple material options to address specific chemical compatibility requirements:
- Standard Stainless Steel Options
- SS304: Suitable for general chemical applications
- SS316: Enhanced corrosion resistance for acids and chlorides
- SS316L: Low carbon variant for welding applications
- Specialty Alloys
- Hastelloy C276: Excellent for HCl, sulfuric acid environments
- Titanium Grade 2: Aggressive chloride environments
- Monel 400: Alkaline solutions and hydrofluoric acid
- Lined Valve Options
- PTFE-lined bodies for highly corrosive media
- Glass-filled PTFE seats for abrasive chemicals
- Rubber-lined for slurry and solid-handling applications
“The material selection process for under-tank ball valves should consider not just the primary chemical being handled, but also potential contamination, temperature fluctuations during cleaning cycles, and the effects of long-term exposure to potentially concentrated solutions.”
