Rubber-Lined Butterfly Valves: Introduction, Structural Features & Technical Parameters

Rubber-Lined Butterfly Valves refer to valves where the butterfly disc and the connection part with the valve body are covered with rubber. These valves can be used to control the flow of various types of fluids, such as water, steam, oil products, gas, slurry, various corrosive media, liquid metals and radioactive fluids.

Structural 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.
