Fluid temperature: High temperature fluids (above 450 ℃) should choose high-temperature resistant valves, such as chromium molybdenum steel high-temperature gate valves used in steam pipelines. Low temperature fluids (below -40 ℃) require valves with good low-temperature toughness, and low-temperature ball valves are commonly used in liquid nitrogen and liquid oxygen pipelines.

Mbale ya Gulugufe ndi mtundu wa valavu yomwe imagwiritsa ntchito chimbale chotsegulira ndi kutsitsa kuti lizizungulira ndi mtsogolo pafupifupi madigiri 90 kuti mutsegule, pafupi, kapena kuwongolera kuchuluka kwa. Mavesi a gulugufe samangokhala ndi kapangidwe kambiri, kukula kochepa, kulemera kowoneka bwino, kukula kochepa, komanso kuthamanga kothamanga, komanso kukhala ndi ntchito yotsika kwambiri.

Makunja a mpira amagwiritsidwa ntchito kwambiri m'magulu a mafakitale opanga mafakitale chifukwa cha mapulogalamu awo osiyanasiyana, kuyeserera kwapamwamba kwambiri, komanso kusavuta kugwira ntchito.

Mu mphamvu yamagetsi, mapaipi a mafuta ndi mafuta, kachitidwe kamadzi, ndi ntchito zina za mafakitale, mavesi pachipata, ndi zida zowongolera zowongolera.
