The robust construction paired with fusion bonded epoxy coating ensures a long service life even in demanding environments.
Flexible Operation and Wide CompatibilityAvailable with lever or gear operation, the valve provides ease of use and accurate flow regulation. With wafer type face-to-face dimensions compliant with ISO 5752 and the capacity to connect to PN10, PN16, and ANSI 150 flanges, installation is straightforward and adaptable to new or existing setups.
FAQ's of CI061 Cast Iron Butterfly Valve PN-16 (Wafer Type):
Q: How is the CI061 Cast Iron Butterfly Valve typically installed?
A: This wafer type valve is installed between two flanges and is compatible with PN10, PN16, or ANSI 150 flange standards. Its flexible design allows for easy integration into new or existing pipelines without the need for extensive modifications.
Q: What media can the CI061 Butterfly Valve handle?
A: The valve can control the flow of water, air, oil, gas, and steam, making it suitable for a broad range of applications within water treatment plants, HVAC systems, fire protection networks, and other industrial processes.
Q: When should I use a lever-operated version vs. a gear-operated version?
A: Lever operation is ideal for smaller valve sizes or when quick open/close action is needed. Gear operation is preferred for larger sizes (usually above 8 inches), or when precise flow modulation and reduced manual effort are important.
Q: Where can this butterfly valve be utilized in industrial systems?
A: The CI061 valve is suitable for use in water distribution, cooling and heating circuits (HVAC), fire protection systems, and process pipelines in various industrial settings where manual flow control is required.
Q: What is the process for selecting the appropriate seat and disc material?
A: Selection depends on the application's media and temperature range. EPDM is suitable for most water applications, NBR offers compatibility with oil and gas, and PTFE provides chemical resistance. Disc options-ductile iron or stainless steel-are chosen based on the corrosiveness or abrasiveness of the media.
Q: What are the main benefits of using the CI061 Wafer Type Butterfly Valve?
A: Key benefits include its durable construction, corrosion-resistant epoxy coating, versatile seat and disc material options, ease of operation, leakage tightness (Class VI), straightforward installation, and wide compatibility with various flange standards.
