The Soft Back Flange Butterfly Valve is a versatile and efficient valve designed for controlling the flow of liquids, gases, and slurries in a variety of industrial applications. This valve is particularly noted for its ability to offer reliable sealing and minimal leakage, making it ideal for systems where tight shut-off is essential. The valve features a soft back seat that ensures a secure and leak-proof seal between the valve body and the flange connection, providing enhanced sealing performance under various pressures and temperatures.

The butterfly valve consists of a circular disc that rotates on a central shaft to regulate flow. When the valve is in the closed position, the disc presses tightly against the valve seat, ensuring a tight seal. When opened, the disc rotates to allow fluid or gas to pass through with minimal resistance, making it an energy-efficient solution for regulating flow.

The soft back flange design adds an extra layer of sealing reliability by using a soft material—such as elastomeric rubber or PTFE—on the valve’s back seat. This material ensures a positive seal, even under fluctuating pressures, and reduces the risk of leakage, extending the valve’s service life. The soft back seat also helps in reducing friction between the valve and the pipeline, which minimizes wear and tear over time.

Constructed from durable materials like stainless steel, cast iron, or carbon steel, the Soft Back Flange Butterfly Valve is built to withstand demanding environments. Its robust construction makes it suitable for use in industries such as water treatment, HVAC, chemical processing, and power generation.

The valve’s ease of installation, simple operation, and low maintenance requirements make it a cost-effective and reliable solution for flow control, offering both operational efficiency and long-term durability.
