1. Chiyambi chachidule
Mayendedwe a valavu ndi perpendicular kwa madzimadzi malangizo, chipata ntchito kudula sing'anga. Ngati ikufunika kulimba kwambiri, mphete yosindikizira yamtundu wa O itha kugwiritsidwa ntchito kuti asindikize ma-bi-directional.
Valavu yachipata cha mpeni ili ndi malo ochepa oyikapo, osavuta kuunjikira zinyalala ndi zina.
Vavu yachipata cha mpeni nthawi zambiri iyenera kuyikidwa molunjika pamapaipi.
2. Kugwiritsa ntchito
Chovala ichi cha mpeni chimagwiritsidwa ntchito m'makampani opanga mankhwala, malasha, shuga, zimbudzi, kupanga mapepala ndi madera ena ambiri. Ndi valavu yabwino yosindikizidwa, makamaka yoyenera kusintha ndi kudula chitoliro mu makampani a mapepala.
3. Mbali
(a) Chipata chotsegula m'mwamba chimatha kupukuta zomatira pamalo osindikizira ndikuchotsa zinyalala.
(b) Kapangidwe kafupikako kumatha kupulumutsa zida ndi malo oyika, komanso kuthandizira bwino mphamvu ya payipi.
(c) Kapangidwe ka chisindikizo chasayansi kumapangitsa chisindikizo chapamwamba kukhala chotetezeka komanso chogwira ntchito komanso chokhazikika
(d) Mapangidwe olimba pa thupi la valve amapangitsa mphamvu zonse
(e) Kusindikiza mbali ziwiri
(f) Malekezero a flange amatha kukhala ma PN16 flange, ndipo kuthamanga kwa ntchito kumatha kukhala kopitilira muyeso wamba.
