Engineering Excellence
& Industrial Dominance

Setting the global gold standard for high-performance fluid control systems.

The 12 butterfly valve stands as a pinnacle of modern industrial engineering, dominating the market through a combination of ultra-low torque operation and superior structural integrity. By utilizing advanced casting techniques and precision machining, we have created a valve that minimizes pressure drop while maximizing flow coefficient (Cv), making it the preferred choice for Fortune 500 energy and chemical plants.

Our technical edge lies in the integration of proprietary alloy coatings and an innovative disc-seat interface. This ensures that the 12 butterfly valve can withstand extreme temperature fluctuations and highly corrosive media without compromising its bubble-tight shut-off capability, significantly reducing maintenance downtime and total cost of ownership for our global clientele.

Fluid Dynamic Optimization

Minimizing turbulence and pressure drops for energy efficiency.

▪Low-Drag Disc: Aerodynamic disc profile reduces cavitation.
▪Linear Flow Control: Precise modulation for stable flow rates.
▪Cv Optimization: Maximum throughput per valve size.

Zero-Leakage Reliability

Absolute sealing technology for safety and environmental protection.

▪Bubble-Tight Shut-off: ANSI Class VI leakage standard.
▪Dynamic Seal Testing: 100% pressure tested before shipment.
▪Dual-Stem Packing: Redundant sealing for toxic media.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries about the 12 butterfly valve.

What is the maximum temperature rating for the 12 butterfly valve?

Depending on the seat material, our B12 series can handle temperatures from -196°C (Cryogenic) up to 600°C (Metal-to-Metal seats).

Do you provide custom actuation for the 12 butterfly series?

Yes, we offer fully integrated pneumatic, electric, and hydraulic actuators tailored to your specific torque requirements and control logic.

How does the 12 butterfly valve ensure bubble-tight shut-off?

We use precision-ground disc edges and high-elasticity seats (like PTFE or Viton) that create a mechanical seal under minimum torque.

Which materials are recommended for highly acidic media?

For extreme acidity, we recommend the B12-AcidRes model featuring Titanium or Hastelloy bodies with PFA linings.

What are the standard lead times for custom B12 orders?

Standard models ship in 2-4 weeks, while custom-engineered alloy valves typically require 6-10 weeks depending on certification needs.

Is the 12 butterfly valve compatible with ANSI/DIN standards?

Yes, we produce both ANSI and DIN compliant versions to ensure seamless integration into existing international piping systems.
