Product Description

The IFLOW triple offset butterfly valve is a precision engineered valve designed for use in industrial piping systems. It features high-strength construction made of cast iron or stainless steel and is suitable for medium and low pressure environments. The valve adopts flange connection design for easy installation and maintenance.

High-quality sealing materials ensure a tight seal when the valve is closed, effectively controlling the flow of liquid or gas within the piping system. The butterfly valve is simple and flexible to operate, and the flow can be easily controlled by rotating the valve disc. In addition, the structural design of the valve reduces fluid resistance, thereby reducing energy consumption. Overall, IFLOW triple eccentric butterfly valve is widely used in industrial pipeline systems for its excellent sealing performance, simple operation and reliable structural design.

The replaceable seat and seal ring system extends the overall service life of each IFLOW valve, thus minimizing downtime without expensive field maintenance or full replacement

Two way zero leakage seal

The unique three eccentric structure makes our valve stable, reliable and easy to maintain

Compared with gate, stop or ball valves of the same size and pressure class, IFLOW butterfly valve saves space and weight, and reduces the installation and maintenance cost to the greatest extent.
