D372F D672F D972F Butterfly valve manufacturer, factory and supplier. D372F D672F D972F Butterfly valve types of PN10 to PN40 (150LB to 300LB) double eccentric butterfly valves are also known as high-performance butterfly valves. D372F D672F D972F Butterfly valve is mainly used for drainage in water plants, power plants, steel mills for smelting, chemical industries, water source spring projects, and environmental facility construction systems. D372F D672F D972F Butterfly valve is particularly suitable for use on water pipelines as regulating and blocking devices. The double eccentric structure is designed such that the valve shaft deviates from the centerline of the sealing surface, creating the first eccentricity; the shaft slightly deviates from the centerline of the pipeline, creating the second eccentricity. The purpose of the eccentricity is to: after the disc plate is opened to approximately 20°, the valve seat and the sealing ring are separated, thereby reducing friction.
The common models of double eccentric butterfly valves include: d372f-10, d372f-16, d372f-25, d372f-40, d372f-64, d372f-100, d672f-10, d672f-16, d672f-25, d672f-40, d672f-64, d672f-100, d972f-10, d972f-16, d972f-25, d972f-40, d972f-64, d972f-100, etc.

D372F D672F D972F Butterfly valve Product Features:
1. The design is reasonable, the structure is compact, it adopts a clamp connection, the weight is light, it is easy to install and disassemble, and it is convenient for maintenance.
2. Adopting an eccentric structure reduces the friction of the sealing ring and extends the service life of the valve.
3. Fully sealed, with zero leakage. It can be used in ultra-high vacuum conditions.
4. By changing the materials of the valve plate sealing ring, butterfly plate, and rotating shaft, it can be applicable to various media and different temperatures.
