Butterfly Valve – Wafer – Ductile Iron – Lever Operated – 316 SS Disk EPDM Seat
The Butterfly Valve is essential for professionals in various industrial sectors, including HVAC, gas, petrochemical, pulp and paper, water and wastewater treatment, and more. This valve is recognised for its precision control and robust construction, making it indispensable in demanding environments.
Design and Efficiency
This valve’s wafer-style body, crafted from ductile iron, is particularly valued for its compact and lightweight design, offering significant space and weight advantages over other valve types. Equipped with a 316 stainless steel disk, it achieves a bubble-tight seal in the closed position and allows smooth flow transitions when open. The disk’s alignment—perpendicular to flow when closed and parallel when open—ensures optimal operation with minimal maintenance required.
Durability and Construction
The valve is coated with a blue epoxy (FBE) finish, enhancing its resistance to corrosive environments. The precision-machined stainless steel disk fits perfectly against an EPDM seat, reducing wear and extending the valve’s life. Operation is simplified with a lever mechanism that requires a quarter turn, complemented by position locks for reliable performance.
Specifications
The valve’s material is ductile iron, enhanced with FBE coating for superior corrosion resistance. Its wafer-type construction makes it compact and efficient for various installations. The operation is lever-operated, which includes a notch plate and position locks for secure usage. It has a pressure rating of 16 BAR (1600 KPA) and has a high-quality EPDM seat that ensures effective sealing. The disc is made of CF8M stainless steel, which offers excellent corrosion resistance and enhances flow capabilities. It can operate from -15°C to 110°C, making it suitable for various conditions. The sizes available range from 50mm (2”) to 200mm (8”).
Application and Performance
The valve’s pinless square drive stainless steel stem and efficient lever mechanism meet the rigorous demands of general and severe service applications. From high-volume water treatment processes to precise flow control in food processing plants, the Butterfly Valve – Wafer – Ductile Iron – Lever Operated – 316 SS Disk EPDM Seat is a reliable, cost-effective choice for managing fluid dynamics in an industrial setting.
