Wafer Butterfly Valve

Triple Offset Wafer High Performance Butterfly Valve

Type:Triple Eccentric

Series:D73H-150LB

Size: DN40-DN600/2”-24”

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

Design standard: API/EN/JIS

Service: OEM&ODM

The triple eccentric butterfly valve is a metal hard-seal valve. The valve stem, valve plate, and sealing surface form a triple eccentric structure, completely eliminating the friction during opening and closing. This high performance butterfly valve combines high pressure, high temperature, wear resistance, and zero leakage characteristics, making it suitable for harsh industrial conditions.

    Characteristics

    The triple eccentric butterfly valve adopts a three-offset structure, which eliminates friction between sealing surfaces during opening and closing. Equipped with metal hard seal, it features excellent high temperature resistance, pressure resistance and abrasion resistance. It provides reliable bi-directional tight shutoff with low operating torque. Compact in structure, it can be fitted with various actuators and works stably under harsh working conditions.

    Advantages

    1.Sealing Advantages:

    The triple eccentric butterfly valve adopts a triple eccentric frictionless structure, ensuring no abrasion of the sealing surface throughout the entire opening and closing process, thereby completely solving the problem of wear and leakage in ordinary butterfly valves. The metal hard seal achieves bidirectional zero leakage, providing stable sealing that is unaffected by high temperatures, high pressures, and pressure differential changes.

    2.Advantages in Working Condition Resistance:

    The high performance butterfly valve resistant to high temperatures, high pressures, erosion, and particulate impurities. Capable of withstanding harsh working conditions such as steam, high-temperature flue gas, heat transfer oil, dust, and particulate-containing sewage, it far exceeds the application range of ordinary soft-seal butterfly valves and exhibits extremely strong industrial heavy-duty performance.

    3,Service Life and Operation and Maintenance Advantages:

    The frictionless design significantly extends the valve's lifespan, making it suitable for high-frequency opening and closing, as well as long-term continuous operation. It features a small operating torque, easy to switch, low failure rate, stable structure, shock resistance, and durability. The maintenance workload is minimal, resulting in a lower overall cost of use.

    Application Scenarios

    The triple offset valve butterfly is widely applied in power, metallurgy, petrochemical and heat supply industries. Suitable for pipelines carrying high-temperature steam, flue gas, thermal oil, dusty fluid and particle-containing wastewater. It is also a reliable option for gas delivery and other heavy-duty industrial piping systems.
