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
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.
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.
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.
Packing
Standard export wooden case packaging
Application Scenarios
The replaceable seat eccentric butterfly valve is widely applied in power plant desulfurization ducts, heating high-temperature steam pipelines, metallurgical furnace flue gas pipes, petrochemical thermal oil lines and industrial wastewater piping with solid particles.
Frequently Asked Questions (FAQ)
The modular seat can be replaced directly on the pipeline without removing the entire valve, significantly saving maintenance time and reducing operational costs.
This valve is designed to withstand extreme working temperatures ranging from -190°C up to 700°C.
Yes, it features a triple eccentric structure that ensures self-tightening, bidirectional zero leakage sealing even under high pressure.
The valve is manufactured using high-quality investment casting and complies with API, EN, and JIS standards.
While the standard operation is manual (handle), it can be equipped with pneumatic or electric actuators for flexible, remote automation control.
We use standard export wooden case packaging to ensure the valve is safely protected during transportation.
