Renewable metal seat butterfly valve triple eccentric structure
Eccentric Flange Butterfly Valve

Renewable metal seat butterfly valve triple eccentric structure

Type:Triple Eccentric

Series:D43H-150LB

Size: DN40-DN600/2”-24”

Pressure rating: PN6/PN10/PN16/5K/10K/150LB/300LB/600LB

Design standard: API/EN/JIS

Service: OEM&ODM

This removeable seat metal seal butterfly valve features modular replaceable seat which can be changed on line without valve removal. Stellite hardfacing creates metal-to-metal sealing; triple eccentric design ensures friction-free operation and self-tightening bidirectional tight shutoff. Solid flanged body is pressure-resistant and compatible with pneumatic actuator for high-temperature and abrasive medium service.

    Characteristics

    This replaceable seat metal-to-metal butterfly valve adopts triple eccentric structure with stellite hardfacing. The modular seat can be replaced on pipeline without removing the whole valve to save maintenance cost. Featuring friction-free opening and self-tightening bidirectional zero leakage, it withstands high temperature and particle erosion. Equipped with flanged ends and optional pneumatic actuator, it is widely used for steam, flue gas and abrasive medium in power, heating and chemical industries.

    Advantages

    1.Convenient maintenance and cost-effective repair

    The renewable valve seat is modular and can be replaced individually without dismantling the entire valve or the pipeline, enabling quick on-site replacement and significantly reducing downtime and spare parts costs.

    2.Metal hard seal, strong adaptability to working conditions

    The metal to metal seat is resistant to high temperatures and dust particle erosion, free from rubber aging, featuring triple eccentricity with no friction, and achieving zero leakage in both directions under high pressure.

    3.The flange structure is sturdy, and the drive selection is flexible

    The integral flange is pressure-resistant and seismic-resistant, and can be equipped with pneumatic/electric actuators to achieve remote on/off control, suitable for automation pipelines across multiple industries.
