Valve limit switch box o se meafaigaluega fa'ato'aga mo le tulaga otometi valve ma fa'ailoga fa'aaliga. E faʻaaogaina e iloa ma mataʻituina le tulaga o le piston i totonu o le valve cylinder poʻo isi mea faʻamalosi. E i ai uiga o le fausaga faʻatusatusa, faʻatuatuaina lelei ma mautu galuega faʻatino, ma faʻaaogaina lautele.
Valve limit switch box, e taʻua foi o valve position indicators, position monitoring indicator, valve position feedback device, valve position switch, e mafai ona faʻapipiʻi i luga o valve switch e pei o le angle valve, diaphragm valve, butterfly valve, ma isi, e faʻaalia ai le valve tulaga i le tulaga o le ki, lea e mafai ona faigofie e faʻafesoʻotaʻi i le PLC poʻo le DCS i luga ole laiga e iloa ai le manatu mamao o le suiga ole tulaga valve.
Ole su'esu'ega ile masini tali valve i atunu'u eseese e tutusa lava, ae o lo'o iai ni eseesega i le tulaga lelei ma le tau. E masani ona vaevaeina masini fa'afeso'ota'i fa'afeso'ota'i ma lē fa'afeso'ota'i. O le tele o masini fa'afeso'ota'i fa'amatalaga o lo'o fa'apipi'iina i suiga fa'ainisinia. Ona o le i ai o vaega faʻafesoʻotaʻi masini, e faigofie ona gaosia aloiafi. O le mea lea, pe a faʻaaogaina i taimi faʻalavelave faʻafuaseʻi, e manaʻomia le faʻapipiʻiina o se pusa paʻu-faʻamaonia, lea e matua faigata lava. Afai e gaoioi soo le alatoto, o le a fa'aitiitia le sa'o ma le ola o le masini tali. Ole masini fa'afeso'ota'i e masani ona fa'aaogaina le sui ole NAMUR. E ui lava e faʻatoʻilaloina faʻaletonu o le masini faʻafesoʻotaʻi faʻafesoʻotaʻi, e manaʻomia le faʻaaogaina ma se pa puipui i taimi faʻalavelave faʻafuaseʻi, ma e maualuga le tau.
