D71F-10P pressure lever handle butt-clamp butterfly valve sealing ring is made of PTFE rubber, mainly used for slightly corrosive media, temperature ≤ 150 ℃, suitable for hot water, sewage, slightly corrosive liquids, acids and alkalis medium. The butterfly valve's butterfly plate is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, the rotation angle is between 0 ° and 90 °, when rotated to 90 °, the valve is fully open. Widely used in food, medicine, chemical and other net pipeline and industrial environmental protection, water treatment, high-rise buildings, water supply and drainage pipelines for opening and closing or regulating the flow of media.
Product Features
- Small and lightweight, easy to dismantle and maintain, and can be installed in any position.
- Simple and compact structure, quick opening and closing with 90° rotation.
- Low operating torque, labor-saving and lightweight.
- Flow characteristics tend to be straight, good regulation performance.
- The number of opening and closing tests is up to tens of thousands of times, with a long service life.
