I-F * F * Ivalvu yokuphepha enentambo engu-F iyivalvu esetshenziselwa ukukhipha ukucindezela okukhulu kumapayipi, eyaziwa nangokuthi i-valve yokuphepha kokucindezela.Yakhiwe ngomzimba we-valve, i-spring elungisayo, i-piston, indandatho yokuvala, ikhava ye-valve, nezinye izingxenye.Lapho ingcindezi epayipini idlula inani elibekiwe, i-valve ivula ngokuzenzakalelayo ukukhipha ukucindezela okukhulu.Lolu hlobo lwe-valve yokuphepha lungavikela amapayipi nezinto zokusebenza ekugcwalisweni kwengcindezi noma ukushintshashintsha kwengcindezi ngengozi.F * Amavalvu okuphepha anentambo ka-F avame ukusetshenziswa emigqeni yokukhiqiza ezimbonini ezifana ne-petroleum, i-petrochemical, amakhemikhali, i-metallurgical, namandla, ikakhulukazi ukulawula ukusebenza kwemishini namasistimu wamapayipi ngaphansi kwezimo zokucindezela okukhulu.Lo mkhiqizo unezici zekhwalithi ethembekile, ukusetshenziswa okulula, nokusebenza okunembile.Ingakwazi ukuzivumelanisa nobubanzi obuhlukahlukene bamapayipi kanye namazinga okucindezela, futhi isetshenziswa kabanzi ezikhathini ezihlukahlukene zezimboni, njengezindawo zamandla, izitshalo zamandla enuzi, i-petrochemical nezinye izimboni.Ukusetshenziswa kwama-valve okuphepha kubanzi kakhulu ezimbonini ezifana nowoyela negesi yemvelo.Emishinini yenqubo yezimboni ezifana ne-petroleum, i-petrochemical, amakhemikhali, i-metallurgical, namandla, inkinga yokuvuza ivame ukwenzeka.Umsebenzi wama-valve okuphepha uwukufinyelela ukulawula okuzenzakalelayo nokuqinisekisa ukuphepha kwemishini nabasebenzi.Kweminye imikhumbi enengcindezi ephezulu kanye nama-reactors, ama-valve okuphepha nawo angamathuluzi okulawula abalulekile.Kafushane, i-valve yokuphepha enentambo engu-F * F iyi-valve yamapayipi ebalulekile esetshenziswa ikakhulukazi ukulawula ukusebenza kwemishini nezinhlelo zamapayipi ngaphansi kwezimo zokucindezela okukhulu, ukuvikela amapayipi nezinto zokusebenza ekugcwalisweni kwengcindezi, futhi iyithuluzi lokuphepha elibalulekile embonini yesimanje.Lo mkhiqizo unesitifiketi se-CE.
