Isindululo sethu seevalvu zokhuseleko
Safety Uncedo Uxinzelelo Uncedo lokhuseleko Ukunciphisa uxinzelelo ukhuseleko Uxinzelelo oluphantsi Ukhuseleko lwaseNtaliyane valves
namhlanje, BESA inqaku lereferensi kungekuphela nje kwimveliso kunye nophuhliso lweemveliso zayo zemveli, kodwa kunye nenkonzo (ngenkonzo yolondolozo olucwangcisiweyo olunikezelayo) kunye nokuthengiswa kweemveliso ezintsha ezikwazi ukwanelisa uluhlu olubanzi lweemfuno.
Siyila kwaye senze iivalvu zokhuseleko ezifanelekileyo ukukhutshwa kwe iigesi, umphunga kunye nolwelo.
BESA iivalve zokhuseleko ziyilwa, zenziwe kwaye zikhethwe ngokuhambelana nemiyalelo yaseYurophu 2014/68/EU (PED) kunye no-2014/34/EU (ATEX), API standiiards 520 526 527 kunye nemimiselo yaselwandle ye RINA, Bureau Veritas kunye neDet Norske Veritas.
BESA iivalvu zokhuseleko zigubungela uluhlu olulandelayo lwesicelo
misela uxinzelelo, ukusuka ubuncinane be-0.2 bar ukuya kwi-600 ubuninzi bar;
iqondo lobushushu, ukusuka kumlinganiselo ongama-200°C ukuya kutsho kuma-750°C.
The izinto yolwakhiwo olusetyenziselwa i standukuveliswa kwe-ard yamacandelo alandelayo:
Jula i-ayini
i-carbon carbon
ingxubevange sentsimbi ephantsi
intsimbi engatyiwa (i-ferritic, i-martensitic kunye ne-austenitic)
Kulwakhiwo olulodwa, Besa ngokuqhelekileyo isebenzisa imathiriyeli ye-thermoplastic (PFA, PVDF, ETFE, HALAR) kunye ne-alloys ezifana Inconel, Hastelloy, Monel, Duplex.
Zonke izinto ezisetyenziswayo zihambelana neYurophu yangoku (EN) kunye neMelika (ASTM) standi-ARDS
Ngokubhekiselele kwimilinganiselo yeevalvu zokhuseleko, iimodeli ezinoqhagamshelo olunamaphiko (EN okanye ANSI) zifumaneka kwi-DN 15 (1/2″) ukuya kwi-DN 250 (10″); ngelixa iimodeli ezinemisonto edibeneyo zifumaneka ngobukhulu ukusuka kwi-1/4 "ukuya kwi-2" (i-cylindrical GAS okanye i-conical NPT).
Ngesicelo, kwindawo yayo, BESA inika uncedo olupheleleyo ekwenzeni iimvavanyo yimibutho ephambili (INAIL - RINA – GL – LR – TUEV – BV – DNV – AB, etc.).
