Pankhani ya valavu ya gulugufe ya mtundu wa Wafer, thupi lake ndi lozungulira ndipo lili ndi mabowo ochepa ozungulira omwe sali opindidwa. Mitundu ina ya Wafer ili ndi awiri pomwe ina ili ndi anayi kapena asanu ndi atatu.
Mabowo a flange amalowetsedwa kudzera m'mabowo a ma bolt a ma flange awiri a mapaipi ndi mabowo apakati a valavu ya gulugufe. Mwa kulimbitsa ma bowo a flange, ma flange a mapaipi amakokedwa wina ndi mnzake ndipo valavu ya gulugufe imamangidwa pakati pa ma flange ndikugwira pamalo ake.
+ Yoyenera ngati valavu yomaliza
+ Yosavuta kuyika pakati

Pankhani ya valavu ya gulugufe ya mtundu wa Lug, pali otchedwa "makutu" pa thupi lonse lomwe ulusi wake unalumikizidwa. Mwanjira imeneyi, valavu ya gulugufe imatha kumangidwa motsutsana ndi flanges ziwiri za mapaipi pogwiritsa ntchito mabolts awiri osiyana (limodzi mbali iliyonse).
Popeza valavu ya gulugufe imalumikizidwa ku flange iliyonse mbali zonse ziwiri ndi maboluti afupiafupi, mwayi wopumula kudzera mu kukula kwa kutentha ndi wochepa kuposa valavu ya mtundu wa Wafer. Chifukwa chake, mtundu wa Lug ndi woyenera kwambiri kugwiritsa ntchito ndi kutentha kwakukulu.
Komabe, pamene vavle ya mtundu wa Lug ikugwiritsidwa ntchito ngati valavu yomaliza, munthu ayenera kusamala chifukwa mavavu ambiri a gulugufe a mtundu wa Lug amakhala ndi kupanikizika kochepa komwe kumaloledwa monga momwe valavu yomaliza imasonyezera kusiyana ndi momwe kalasi yawo ya kupanikizika "yachizolowezi" imasonyezera.
