The DN50 wafer type butterfly valve with aluminum alloy handle offers an efficient, lightweight, and cost-effective solution for controlling flow in pipelines. Known in the industry as a 2 inch butterfly valve, it is ideal for applications requiring space-saving installation and reliable sealing.
This wafer butterfly valve features a durable ductile iron body, a corrosion-resistant stainless steel disc (CF8), and an NBR seat for excellent sealing performance. The aluminum alloy handle provides easy manual operation while reducing weight and enhancing corrosion resistance.
Designed in a wafer style butterfly valve configuration, it fits snugly between flanges without the need for bolts passing through the body. This compact structure makes it perfect for systems where space and weight are critical factors. The butterfly valve wafer type design ensures bi-directional flow and minimal pressure drop, making it a top choice among high performance butterfly valves in water treatment, HVAC, and chemical applications.
Whether you refer to it as a 2 inch butterfly valve or a wafer type butterfly valve, this model delivers reliable performance with low maintenance.
