Double Flange Triple Eccentric Butterfly Valve

Product Details

Overview:

Butterfly valve  is used for isolating or regulating  flow   and its function allows for quick shut off. There are many different kinds of butterfly valves, each adapted for different pressures and different usage in the industry.


Specifications: 

Nominal diameter: 2" - 72"(DN50 - DN1800)

Pressure range: Class 150 - 600(PN16 - PN100)

Working temperature: -46℃  - +550℃

Body material: Cast Steel, Stainless Steel, Ductile Iron, Carbon Steel, etc

Drive way: Hand wheel, Gear, Electric actuator, etc

Media: Water, Natural gas, Air,  Oil, etc


Main features:

1. The valve is equipped with eccentric tilting tapered valve seat sealing ring for the purpose if pressing out the sealing surface has small frictional resistance. When shutting off, it cleses more and more, so this makes sealing performance reliable, Opening can ensure that the sealing.
2. The special geometric structure makes the butterfly valve free of defect that other butterfly balves are unable to be sealed will due to excessively opening, so as to gurantee good sealing of the surface.
3. The double eccentric butterfly valve structure can gurantee that the valve fundtions mormally under high prssure and overcome the shortcomings that other valve easily leak due to sest deformation when they work under high pressure.
