Name:Metal to metal eccentric lug type butterfly valve

Features
Main configuration characteristic of 815
830 series of butterfly valve is composed of wafer and
flange three eccentricity
then main configuration characteristic of 815
830L series butterfly
valve is edge of body with protruding ears and single flange configuration with screw. 815
830
series of butterfly valve has been widely utilized in petroleum
chemical industry and industrial
environmental protection water treatment
high building
water supplying and draining. The main
characteristic is: due to use three eccentric configuration
hermetic capability reliably
which
ensure disc never touch sealing seat when it start
solve the problem of hermetical seat burden
unequally
prolong service life
and ensure reliable hermetic capability with advantage of high
temperature resistant
wearable antisepsis etc.

 

Standard compliance
Design standard: API 609-83
Flange connection dimension: ANSI B16.5
Structure length: ANSI B16.10-1992
Pressure test: API 598-82
