Jacketed Butterfly Valve

High Temperature Polymer Melt Butterfly Valve for Chemical Fiber & Polymer Processing

The Jacketed Butterfly Valve is specially designed for high-temperature polymer melt applications in chemical fiber and polymer processing industries. The valve adopts a jacketed structure to maintain stable media temperature and prevent polymer solidification during operation.

It is widely used in polyester, nylon, polypropylene, and other polymer melt conveying systems where reliable shut-off and stable flow control are required. The compact butterfly valve structure provides fast operation, excellent sealing performance, and low pressure drop.
