Reliable Corrosion ResistanceProtected by a fusion bonded epoxy coating, the cast iron body and disc ensure long-lasting durability even in challenging environments. The coating defends against rust, chemical exposure, and frequent operation, maintaining performance and extending the valve's service life. This robust design is suited for industries dealing with water, light chemicals, air, or non-corrosive media.
Versatile and Easy to InstallThe valve features a bi-directional sealing design and a mounting pad compliant with ISO 5211, allowing for straightforward installation in both horizontal and vertical positions. With face-to-face dimensions standardized to ISO 5752/EN 558, and adaptable end connections (EN1092, ANSI, JIS, BS), this butterfly valve offers flexibility to meet a wide range of piping system requirements.
High Performance for Demanding ApplicationsEquipped with a stainless steel stem and multiple seat material options, this valve guarantees excellent sealing (Class VI, bubble tight) and a working life exceeding 50,000 cycles. Its quarter-turn operation provides swift flow control, making it suitable for manual levers, gearboxes, or automated actuators powered by electric, pneumatic, or hydraulic systems.
FAQ's of Cast Iron Butterfly Valve:
Q: How do I install a Cast Iron Butterfly Valve with a fusion bonded epoxy-coated body?
A: Installation is straightforward as the valve is designed for both horizontal and vertical positioning. Ensure that the flanges comply with EN1092, ANSI, JIS, or BS standards and that the gasket and bolting are appropriate for the application. The valve's ISO 5211 mounting pad allows easy actuator fitting if automation is required.
Q: What are the primary benefits of using this butterfly valve in water and air systems?
A: The valve's epoxy coating resists corrosion, while the bubble-tight Class VI sealing ensures leak-free operation. The bi-directional flow design and compatibility with multiple seat materials (EPDM, NBR, PTFE, Viton) make it suitable for handling water, air, and other non-corrosive fluids efficiently and reliably.
Q: Where can this cast iron butterfly valve be used?
A: It is widely used in municipal water supply, HVAC, wastewater treatment, oil and gas pipelines, and other systems where non-corrosive media like air, gas, water, and light chemicals are managed. Its flexible connection types (wafer and lug), broad temperature range, and compliance with global standards make it suitable for Indian industrial and commercial applications.
Q: What is the process for selecting the correct seat material for my application?
A: Choose the seat material based on the medium being conveyed and the operating temperature. EPDM and NBR are ideal for water and air, PTFE for higher chemical resistance, and Viton for light chemicals and higher temperature requirements. Consult your supplier with details of your application to ensure optimal seat selection.
Q: How does the valve ensure tight shut-off and prevent leakage?
A: This butterfly valve meets Leakage Class VI (bubble tight) specifications. The precision-engineered disc and seat interface, combined with high-quality sealing materials, provide a secure shut-off, minimizing the risk of fluid leakage even in demanding conditions.
Q: When should maintenance be performed on this butterfly valve?
A: Routine maintenance is recommended at regular intervals based on the number of cycles and fluid conditions. With a working life of over 50,000 cycles and corrosion-resistant components, the valve requires minimal upkeep. Inspect stem, seat, and body coating periodically for optimal performance.
