5 FAQs of 8″ DN200 Wafer type butterfly valve PN16 Cast iron body Ductile iron Nickel plate disc WCB shaft EPDM seat Gear box handwheel

The 8″ DN200 Wafer Type Butterfly Valve with PN16 rating is a robust and reliable solution for controlling flow in various industrial applications. Here are five frequently asked questions about this valve:

1. **What materials are used in the construction of this butterfly valve?**
The valve features a cast iron body for durability and strength, with a ductile iron disc that is nickel-plated to enhance corrosion resistance. The shaft is made of WCB (cast carbon steel), ensuring high tensile strength and longevity. The seat is constructed from EPDM (Ethylene Propylene Diene Monomer), which provides excellent sealing properties and resistance to a wide range of temperatures and chemicals.

2. **What is the pressure rating of this valve?**
This butterfly valve is rated at PN16, meaning it can handle a maximum pressure of 16 bar. This makes it suitable for medium-pressure applications in industries such as water treatment, HVAC, and general industrial processes.

3. **What type of actuation does this valve support?**
The valve comes with a gearbox handwheel for manual operation, allowing for precise control and ease of use. It can also be adapted for automated actuation using electric, pneumatic, or hydraulic actuators, depending on the specific requirements of the application.

4. **Is this valve suitable for high-temperature applications?**
While the EPDM seat offers good temperature resistance, it is best suited for applications with temperatures ranging from -20°C to 120°C. For higher temperatures, alternative seat materials like Viton or PTFE may be recommended.

5. **What are the key advantages of this wafer-type butterfly valve?**
The wafer design ensures a compact and lightweight structure, making it easy to install between flanges without the need for additional gaskets. The nickel-plated disc and WCB shaft provide excellent resistance to wear and corrosion, while the EPDM seat ensures a tight seal and long service life. The gearbox handwheel allows for smooth and efficient operation, even in demanding conditions.

This 8″ DN200 Wafer Type Butterfly Valve is a versatile and cost-effective solution for flow control, offering reliability, durability, and ease of maintenance in a wide range of industrial applications.
