NSW API 602 valavu yapadziko lonse lapansi, gawo lotsegula ndi lotseka la valavu yachitsulo yachitsulo ya boneti ya bawuti ndiye chipata.Mayendedwe a chipata ndi perpendicular kwa malangizo a madzimadzi.Valve yachipata chachitsulo chokhazikika imatha kutsegulidwa kwathunthu ndikutsekedwa, ndipo sichingasinthidwe ndikugwedezeka.Chipata cha valavu yachitsulo chopangidwa ndichitsulo chimakhala ndi malo awiri osindikizira.Magawo awiri osindikizira a valve yodziwika bwino ya pachipata amapanga mawonekedwe a wedge, ndipo ngodya ya wedge imasiyanasiyana ndi magawo a valve.Njira zoyendetsera mavavu opangira zitsulo zachitsulo ndi: manual, pneumatic, magetsi, mpweya wamadzimadzi.
Kusindikiza pamwamba pa valavu yachitsulo chopangidwa ndi chitsulo chokhazikika kumatha kusindikizidwa kokha ndi kupanikizika kwapakatikati, ndiko kuti, kuthamanga kwapakati kumagwiritsidwa ntchito kukanikiza pamwamba pa chitseko ku mpando wa valve kumbali ina kuti zitsimikizire kusindikiza pamwamba, zomwe ziri kudzisindikiza.Ma valve ambiri a pakhomo amakakamizika kusindikiza, ndiko kuti, pamene valavu yatsekedwa, ndikofunikira kukakamiza chipata cha chipata chotsutsana ndi mpando wa valve ndi mphamvu yakunja kuti zitsimikizidwe kuti kusindikizidwa kwa malo osindikizira.
Chipata cha valavu yachipata chimayenda motsatira tsinde la valve, chomwe chimatchedwa valavu ya chipata chokwera (chomwe chimatchedwanso valavu yotsegula).Nthawi zambiri pamakhala ulusi wa trapezoidal pa ndodo yokweza.Mtedza umayenda kuchokera pamwamba pa valavu ndi polowera pa valavu kuti asinthe kayendetsedwe kake kozungulira, ndiko kuti, torque yogwiritsira ntchito kupita kumalo opangira opaleshoni.
Ubwino wa valavu yachitsulo yonyezimira:
1. Kukana kwamadzimadzi otsika.
2. Mphamvu yakunja yofunikira pakutsegula ndi kutseka ndi yaying'ono.
3. Njira yoyendetsera sing'anga siyimalekezeredwa.
4. Mukatsegula kwathunthu, kukokoloka kwa malo osindikizira ndi sing'anga yogwira ntchito kumakhala kochepa kuposa kwa valve ya globe.
5. Mawonekedwe ake ndi ophweka ndipo njira yoponyera ndi yabwino.
