4. Ithiyori yomsebenzi
I-valve yokuhlola ivula ngokuzenzakalelayo iphinde ivale i-disc ukuvimbela ukugeleza okuphakathi ukuya emuva ngokugeleza okuphakathi.
5. Amazinga e-valve asebenzayo kodwa angagcini kulokhu:
(1) API 6D-2002 (2) ASME B16.5-2003
(3) ASME B16.10-2000 (4) API 598-2004

6. Isitoreji & Ukunakekela & Ukufakwa & Ukusebenza
6.1 Ivalvu kufanele igcinwe egumbini elomile nelinomoya okahle .amaphethelo ephaseji kufanele axhunywe ngamakhava.
6.2 Amavalvu angaphansi kokugcinwa isikhathi eside kufanele ahlolwe futhi ahlanzwe njalo, ikakhulukazi ubuso obuhlalayo ukuze kuvinjelwe umonakalo wabo, futhi ubuso obuhlala kufanele bugcotshwe ngamafutha avimbela ukugqwala.
6.3 Ukumakwa kwevalvu kufanele kubhekwe ukuze kuhambisane nokusetshenziswa.
6.4 Imbobo yevalvu nendawo yokuvala kufanele ihlolwe ngaphambi kokufakwa futhi kukhishwe ukungcola uma kukhona.
6.5Indlela yomcibisholo kufanele ifane nendlela yokugeleza.
6.6 Ivalvu yokuhlola idiski eme mpo kufanele ifakwe iqonde epayipini. Ivalvu yokuhlola idiski evundlile ephakamisayo kufanele ifakwe iqonde epayipini.
6.7 Ukudlidliza kufanele kuhlolwe futhi ukuguqulwa komfutho wephayiphi ophakathi nendawo kufanele kuqashelwe ukuze kuvinjelwe umphumela wamanzi.

8. Iwaranti
Ngemuva kokuthi i-valve isetshenzisiwe, isikhathi sewaranti yevalvu yizinyanga eziyi-12, kodwa asidluli izinyanga eziyi-18 ngemuva kosuku lokulethwa. Ngesikhathi sewaranti, umenzi uzohlinzeka ngesevisi yokukhanda noma izingxenye ezisele mahhala ngomonakalo odalwe yimpahla, ubungcweti noma umonakalo inqobo nje uma lokho kusebenza kulungile.
