Description
- The butterfly valve is used for on/off control or modulating the flow of water, air, and oil.
- The 20" wafer butterfly valve is specifically designed to be mounted between two pipe flanges with ANSI standards.
- The valve body is made of cast iron, with epoxy coating for enhanced corrosion resistance and extended service life.
- The butterfly valve features a concentric design, in which the turning axis and axial alignment of the disc are both centered with the valve body, making it compact and cost-effective.
- The valve is operated by a double acting pneumatic actuator that uses compressed air to open and close the valve with a quarter-turn motion, ensuring fast and reliable operation.
- The NBR stem seals provide reliable sealing performance and resistance to oils, water, and hydraulic fluids.
- The NBR seat offers a tight seal and good wear resistance.
- The 316 stainless steel disc offers excellent corrosion resistance, durability, and strength.
- The butterfly valve is designed for use with water, air, oil, and fuel. Typical applications include industrial/process piping, water treatment and irrigation.
