Product Introduction：

Wafer Fully Rubber Lined Butterfly Valve: The valve body and flow channel inner wall, as well as the butterfly plate, are integrally lined with high-temperature vulcanized rubber. 

It employs a clamp-on connection, relying on the pipe flanges on both sides and through bolts to secure the valve body. 

It can be manufactured as an ISO5211 smooth rod high platform, with optional handle, worm gear, pneumatic, and electric actuators.

The medium is in full contact with the rubber lining, isolating the metal valve body. 

Primarily designed for corrosion resistance and economical use as a mid-section shut-off valve in pipelines.

Applicable Conditions: 

Municipal sewage, chemical wastewater, dilute acid and alkali pipelines in pickling production lines. 

Power plant and water plant desulfurization, circulating water, and sludge slurry systems. 

Electroplating, printing and dyeing, and papermaking corrosive process pipelines. 

Seawater desalination and brine solution transportation pipelines. 

Outlet branch pipes and end shut-off valves of complete sets of corrosion-resistant equipment. 

Inlet and outlet valves of environmental protection waste gas scrubbing towers.
