Ductile Iron Concentric Flanged Type EPDM Rubber Lined Butterfly
Valve
Product introduction:
Pneumatic powder butterfly valves are mainly used for opening and
closing material boxes, hoppers, and silos containing powdered or
granular materials. It can be applied to the processing of all
powdered and granular materials. The valve uses the material's own
gravity to intercept and pneumatically transport dry materials. It
can be installed under hoppers, bins, silos, spirals, or other
types of conveyors, as well as connected to pneumatic conveying
pipelines. Due to its unique structure and the use of engineering
materials, this valve has always been a very economical and
efficient choice.

Product features:
1. The aluminum alloy powder use butterfly valve is made of
high-pressure cast aluminum alloy, which has the characteristics of
light weight and high strength. The valve body consists of two
high-pressure die cast half valve bodies, and the valve plate is
made of polymer composite material, which is wear-resistant
2. The sealing surface of the valve seat flange adopts a large wide
edge and large arc design, which adapts to various standard flange
connection requirements and is easy to install and seal. The valve
plate is lined with a wear-resistant polymer material with a steel
core, which forms a highly wear-resistant soft seal with a
wear-resistant rubber sealing ring, suitable for the treatment of
various dust and particulate materials
3. Aluminum alloy powder butterfly valves are widely used in the
processing of powdered and granular materials, often installed
under hoppers, bins, silos, screw pumps or other types of
conveyors, as well as connected to pneumatic conveying pipelines.
It utilizes the material's own gravity to intercept and
pneumatically transport dry materials
4. Aluminum alloy powder use butterfly valve easy to install, often
installed under equipment such as hoppers, silos, screw pumps, and
connected to pneumatic conveying pipelines. The valve body is
lightweight, easy to handle and install
Drive mode: Aluminum alloy dust butterfly valve can be equipped
with various drive devices, such as handle, turbine, pneumatic and
electric actuators. By using anti condensation technology, the
service life of the driving device can be extended.
