Diaphragm Valve

BFLON Lined Valves is a reputable Lined PTFE Diaphragm Valve manufacturer with more than 25 years of experience in industrial pipeline valves, process engineering, design, erecting and commissioning. Our company is certified to ISO 9001, ISO 14001, and OHSAS 45001, and provides reliable, safe, and quality flow control characteristics to the world's most challenging industrial applications.

The BFLON Lined PTFE Diaphragm Valve products are manufactured to provide the best performance in leak-free operation, corrosion resistance, and ease-in-operation, when exposed to aggressive chemical attack. The metal body is robust, fully lined with high grade PTFE, and all wetted parts are protected from acid, alkalis and solvents as well as any corrosion. The flexible diaphragm serves as both the closing element and the sealing surface of the valve, effectively separating the internal mechanical components from the process media - an essential feature where high-purity or contamination-preventing processing techniques are employed.

Some key characteristics of the Lined PTFE Diaphragm Valve include, but are not limited to - leak-tight seals, smooth actuation and flow control, low operating torque, and little or no maintenance. The BFLON Lined PTFE Diaphragm Valve can be manufactured in either a weir-type or straight-through pattern valve. Actuation can be manual, pneumatic, or electric for practically any operational requirement.

Uses for our PTFE-Lined Diaphragm Valves include chemical and petrochemical processing, pharmaceutical production, water and waste water treatment, food and beverage processing, and many more applications where safety, reliability, and chemical resistance are key to your industry.

By choosing BFLON as your Lined PTFE Diaphragm Valve manufacturer, you are choosing a company that draws from advanced engineering, certified quality systems, and decades of industry experience to make valves that deliver plant efficiency, process safety, and long service life.
