Below, we detail the key features, technical specifications, and benefits that make our butterfly valve a preferred choice for professionals worldwide.
Key Features and Benefits
- Durable Ductile Iron Construction: The valve body is made from high-grade ductile iron (GGG40/GGG50), offering superior tensile strength and impact resistance compared to cast iron, ensuring long-term reliability even in demanding environments.
- DIN 3202 Compliance: Manufactured to strict DIN 3202 face-to-face dimensions, this valve ensures easy installation and interchangeability with other standard valves, reducing downtime and maintenance costs.
- Versatile Seat Options: Available with EPDM, NBR, or PTFE liners, the valve can handle a variety of media, including water, air, oil, and mild chemicals. This flexibility allows you to select the best material for your specific application.
- Bubble-Tight Shut-Off: The resilient seat design provides a bubble-tight seal in both directions, preventing leakage and ensuring efficient flow control.
- Low Torque Operation: The streamlined disc design minimizes pressure drop and requires low operating torque, making manual operation easy and reducing actuator size and cost for automated systems.
- 3-Year Warranty: We stand behind our product with a comprehensive 3-year warranty, covering manufacturing defects and giving you peace of mind.
- Mill Test Report Included: Each valve can be supplied with a Mill Test Report (MTR) for material traceability, a critical requirement for many industrial and engineering projects.
