NSF61 And NSF 372 AWWA C504 Ductile Iron Double Flange Double Eccentric Butterfly Valve
Features:
Arch shape design, stronger ribs on back side, size DN350-1200MM
This can help to BV has a better flow coefficiet when water through the holes on the disc in fully open position, water will stabilize the disc and het a better flow coefficeint.
Double eccentric design, less wearing of rubber.
Less compression for rubber, longer life for rubber. When double eccentric BV in fully open position, the compression of the rubber is much less than the concentric type of BV. It gives a longer life time for rubber comparing with double eccentric and concentric BV.
Body Platform:
Keep the sleeve bearing fully in the hole, strong protection
No harming to the bearing during operation
