Vavu ya matope ya DEMCO 7500-psi imakwaniritsa zofunikira zolimba za 7500-psi zogwirira ntchito pobowola zitsime zozama. Vavu ya matope ya DEMCO 7500-psi imabwera pamsika uwu ndi ukadaulo wotsimikizika kuchokera kwa mtsogoleri wamakampani. Pamene msika unkafuna valavu yobowola matope ya 7500-psi, valavu ya matope ya DEMCO 7500-psi idayambitsidwa kuti ikwaniritse vutoli. Izi ndizoyenera chifukwa mavalavu a matope a DEMCO (2000 mpaka 5000 psi) akupitilizabe kukhala mavalavu apamwamba kwambiri obowola matope, monga momwe akhala akuchitira kwa zaka zoposa 30.
Valavu ya chipata cha DEMCO 7500 imapezeka m'makulidwe a 2" mpaka 6" yokhala ndi maulumikizidwe a butt weld kapena malekezero opindika. Valavu ya DM dothi, ndi chipata cholimba, tsinde lokwera, mavavu a chipata okhala ndi zisindikizo zolimba. Amapangidwira matope, simenti, kusweka ndi ntchito yamadzi ndipo ndi osavuta kugwiritsa ntchito komanso osavuta kusamalira. Boneti imachotsedwa mosavuta kuti iwunikire ziwalo zamkati ndi/kapena kusinthidwa popanda kuchotsa valavu pamzere. Kapangidwe kameneka kamalola ntchito yachangu komanso yosavuta popanda kugwiritsa ntchito zida zapadera.
Valve ya DM dothi, yokhala ndi kapangidwe kapamwamba kwambiri, imakhala ndi luso lolondola komanso mfundo yotsimikizika, yapangidwa kuti ikwaniritse zofunikira kwambiri pakubowola mafuta masiku ano.
Chopangidwa makamaka kuti chigwiritsidwe ntchito pobowola zitsime zakuya, valavu yamatope ya DEMCO 7500-psi imasankhidwa kuti igwiritsidwe ntchito pobowola motere:
Manifold a standpipe.
Ma valve a block ambiri a pampu.
Ma valve obowola zinthu mopupuluma kwambiri.
Utumiki wa frac wothamanga kwambiri.
