20" Pneumatic Wafer Butterfly Valve

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.
