Frequently Asked Questions (FAQ):
-
Q: What does "DN80" mean in this valve specification?
A: DN80 refers to the nominal diameter of the valve, approximately 80mm. It indicates the size of the pipeline connection the valve is designed for. -
Q: What is the significance of DNV BV approval?
A: DNV BV approval means the valve has been certified by Det Norske Veritas and Bureau Veritas, two major international certification bodies. This is often required for equipment used in marine, offshore, and certain industrial applications to ensure safety and compliance. -
Q: Can this valve be used with other seal materials besides EPDM?
A: Yes, as a manufacturer, we can provide valves with alternative seal materials such as PTFE, Viton, or NBR based on your specific fluid compatibility and temperature requirements. -
Q: Is the valve suitable for high-temperature applications?
A: The standard EPDM seal has a typical operating temperature range. For higher temperatures, we can recommend or supply valves with seals designed for elevated temperature conditions. -
Q: What types of actuators are available for this butterfly valve?
A: The valve can be supplied with a manual lever or gear operator. Pneumatic or electric actuators are also available as optional features for automated control systems. -
Q: How does the wafer design differ from other butterfly valve types?
A: A wafer butterfly valve is designed to be installed between two pipeline flanges using bolts that pass through the flanges, not the valve body. This makes it lighter and more compact compared to lug-type valves. -
Q: What industries commonly use this JIS F7481 butterfly valve?
A: It is widely used in water treatment, chemical processing, HVAC, food and beverage, marine, and general industrial fluid handling systems. -
Q: Can I order this valve in different sizes?
A: Absolutely. While this product focuses on DN80, we manufacture wafer butterfly valves in a range of sizes. Please inquire for other nominal diameters.
