Product Description
The D71F-16Q Handle Wafer-Type PTFE Butterfly Valve is suitable for use in clean piping systems in the food, pharmaceutical, and chemical industries, as well as in industrial environmental protection, water treatment, high-rise buildings, and water supply and drainage systems for opening, closing, or regulating the flow of media. The disc of the handle wafer-type butterfly valve is mounted perpendicular to the diameter of the pipeline. Within the cylindrical passage of the butterfly valve body, the disc rotates around its axis through an angle ranging from 0° to 90°. When rotated to 90°, the valve is in the fully open position.
Product Features
- Compact and lightweight, it is easy to assemble, disassemble, and maintain, and can be installed in any location.
- Simple and compact design; opens and closes quickly with a 90° rotation.
- Low operating torque; easy to use and lightweight.
- The flow characteristics approach a linear relationship, and the system offers excellent control performance.
- It has undergone tens of thousands of opening and closing cycles and has a long service life.
- A complete seal has been achieved, with zero gas leakage detected during testing.
