The high performance butterfly adopts double eccentric or triple eccentric disc structures, eliminating friction between the sealing surface and valve seat during operation. This design significantly extends sealing service life while reducing operating torque.
The multi-layer metal sealing structure provides excellent resistance to high temperature, high pressure, and erosion, making it suitable for dusty, particle-containing, and high-temperature steam applications.
The streamlined valve body design improves flow capacity and reduces pressure loss. With bidirectional pressure resistance, the valve ensures reliable shut-off under both forward and reverse flow conditions. The valve stem features multiple anti-blowout and anti-leakage protection structures, improving operational safety.
It can be equipped with intelligent positioners and electric actuators for integration into factory DCS automation systems, providing both reliable shut-off and high-precision control functions.
Application Areas:
Petroleum refining high-temperature pipelines, power plant steam systems, coal chemical dust removal systems, metallurgical high-temperature cooling systems, renewable energy heat transfer oil pipelines, and hazardous chemical process pipelines.
