NSW API 602 valavu yapadziko lonse lapansi, gawo lotsegula ndi lotseka la valavu yachipata chachitsulo cha boneti ya bawuti ndiye chipata.Mayendedwe a chipata ndi perpendicular kwa malangizo a madzimadzi.Valve yachipata chachitsulo chopangidwa ndichitsulo imatha kutsegulidwa kwathunthu ndi kutsekedwa, ndipo sichingasinthidwe ndikugwedezeka.Chipata cha valavu yachitsulo chopangidwa ndichitsulo chimakhala ndi malo awiri osindikizira.Malo awiri osindikizira a valve yodziwika bwino ya pachipata amapanga mawonekedwe a wedge, ndipo mbali yake ya wedge imasiyana ndi magawo a valve.Njira zoyendetsera ma valve opangidwa ndi zitsulo zopangira zitsulo ndi: manual, pneumatic, magetsi, mpweya wamadzimadzi.
Kusindikiza pamwamba pa valavu yachitsulo chopangidwa ndi zitsulo zotsekedwa kungathe kusindikizidwa kokha ndi kupanikizika kwapakati, ndiko kuti, kuthamanga kwapakati kumagwiritsidwa ntchito kukanikizira pamwamba pa chitseko ku mpando wa valve kumbali ina kuti zitsimikizire kusindikiza pamwamba, zomwe ziri kudzisindikiza.Ma valve ambiri a zipata amakakamizika kusindikiza, ndiko kuti, pamene valavu yatsekedwa, ndikofunikira kukakamiza chipata cha chipata chotsutsana ndi mpando wa valve ndi mphamvu yakunja kuti zitsimikizidwe kusindikizidwa kwa malo osindikizira.
Chipata cha valavu yachipata chimayenda motsatira tsinde la valve, chomwe chimatchedwa valavu ya chipata chachitsulo (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. Low madzimadzi kukana.
2. Mphamvu yakunja yofunikira pakutsegula ndi kutseka ndi yaying'ono.
3. Mayendedwe oyenda a sing'anga sali ochepa.
4. Mukatsegula kwathunthu, kukokoloka kwa malo osindikizira ndi sing'anga yogwira ntchito kumakhala kochepa kwambiri kuposa valve ya globe.
5. Mawonekedwe ake ndi ophweka ndipo njira yoponyera ndi yabwino.
