Replaceable metal seat eccentric lug type butterfly valve

The renewable seat triple eccentric lug butterfly valve adopts replaceable seat and metal-to-metal hard seal structure. With friction-free operation and self-tightening bidirectional zero leakage, it resists high temperature and particle erosion. The special lug thread design supports single-side blind and single-side connection, ideal for pump ports and branch pipelines. The on-site replaceable seat greatly reduces long-term maintenance costs.

1.Low maintenance cost, no need to replace the entire valve

There is only the seat needs replacement instead of the whole triple offset butterfly valve. On-site maintenance without pipe disassembly greatly reduces downtime and spare part costs.

2.Lug connection is flexibly installed, adapting to the pump port branch pipeline

This replaceable butterfly valve with unique lug thread structure supports single-side blind closure and unilateral connection. Perfect for pump inlet/outlet and branch pipelines with strong tension resistance and easy installation.

3.Heavy-duty and durable, with wide adaptability to working conditions

All-metal hard seal adapts to high temperature, flue gas, dusty and abrasive media. The friction-free triple eccentric design of this metal to metal butterfly valve ensures stable zero leakage under large pressure difference.

Standard export wooden case packaging

The replaceable lug type triple offset butterfly valve widely used for pump inlet and outlet pipelines, pipeline branch and bypass systems, power plant desulfurization, heating steam piping, metallurgical flue gas, chemical abrasive media and industrial wastewater pipelines.
