VALTECCN is a professional butterfly valve supplier and manufacturer, providing high quality butterfly valve products for various industrial applications. Among them, ductile iron butterfly valve, wafer style, PN16 is an economical and practical butterfly valve with the following characteristics:

• The valve body is made of ductile iron, which has good mechanical properties and corrosion resistance. Ductile iron is a type of cast iron containing nodular graphite, which is more ductile and impact-resistant than ordinary gray iron. Ductile iron also has higher strength and ductility, allowing it to withstand greater stress and deformation.
• Clip-on connection, easy to install and disassemble, saving space. Wafer style butterfly valves can be sandwiched directly between two flanges without bolts or gaskets, reducing weight and cost. Wafer butterfly valves can also be installed in any direction, improving flexibility and adaptability.
• PN16 pressure rating, suitable for medium and low pressure working conditions. PN16 is a pipeline system with a pressure of 16 bar, which is equivalent to a maximum allowable working pressure of 16 bar. Ductile iron butterfly valve, wafer type, PN16 can work normally in the temperature range of -10°C to 120°C.
• Rubber gasket seals the seat ring, providing a two-way airtight closure and isolating the media. The gasket sealing seat is an elastic material that can fit tightly with the valve plate to form an effective sealing layer. Rubber pad sealing seat ring can choose EPDM or NBR rubber and other materials according to different media.
• Stainless steel valve stem and aluminum bronze or stainless steel valve plate ensure the strength and durability of the valve. The stainless steel valve stem and valve plate have excellent anti-oxidation and anti-corrosion capabilities, and can be used for a long time in various harsh environments. Aluminum bronze or stainless steel valve plate also has good wear resistance and hardness, which can effectively reduce friction loss and leakage risk.
• Manual or worm gear transmission, flexible and reliable operation. The manual operation mode is suitable for small-caliber or low-frequency switch control, which is simple and convenient. The gear transmission method is suitable for large-caliber or high-frequency switch control, which can improve operating efficiency and precision.

Ductile iron butterfly valve, wafer style, PN16 is a heavy elastic sealing butterfly valve suitable for food and beverage, paper, chemical, mining, water treatment, HVAC, electric power and automotive industries. It can be used to cut off or regulate the flow of media, and it only takes a quarter turn to fully open or close the valve. VALTECCN’s butterfly valve products meet the standards of MSS-SP-67 and API 609, and have passed strict quality inspection and performance testing.
