Soft Seal Butterfly Valves: Introduction, Product Features & Technical Parameters

Soft Seal Butterfly Valves mainly adopt rubber or PTFE (polytetrafluoroethylene) sealing. The butterfly disc and valve stem are generally made of carbon steel or stainless steel. They are suitable for water supply and drainage, gas pipelines in industries such as food, medicine, chemical, petroleum, electric power, textile, and papermaking with a temperature of ≤80～120℃, serving to regulate flow and cut off media.

Product Features

• The sealing element is replaceable, with reliable sealing performance to achieve two-way sealing and zero leakage.

• Small operating torque, easy to operate, labor-saving and flexible.

• Can be installed in any position, convenient for maintenance.

• Novel, reasonable and unique design, light weight, and quick opening and closing.

• The sealing material is aging-resistant and weakly corrosion-resistant, with a long service life.
