Product Detail

Product overview:

This series of butterfly valves adopts a medium line design, and its main structure consists of valve body, valve disc, valve seat, valve stem, and transmission operating mechanism. The valve seat adopts a detachable structure and can be made of materials that are resistant to high temperature, low temperature, corrosion, light, and aging according to the physical and chemical characteristics of different media. It can be widely used as a regulating and intercepting device in fluid pipelines such as water supply and drainage, chemical, food, medicine, textile, hydropower, ships, metallurgy, energy systems, etc.

Product Features：

The valve seat adopts a detachable design for easy on-site maintenance, and adopts a full basin design, which is not easily affected by material jamming.
The valve disc material adopts a streamlined design, which can be used in both directions, with low flow resistance and excellent flow
characteristics.
The shaft pin adopts a US patented design with a pull-out pin structure, which can tightly bond the valve flap and shaft together without
loosening or weakening the strength of the shaft, and has good interchangeability.
The selection of operating mechanisms is flexible, and different rotating devices such as manual, electric, and pneumatic can be configured
according to user needs.
