I-Trunnion DBB Ball Valve

Ama-Double Block and Bleed Valves aqinisekisa umsebenzi wokuhlukanisa kabili ngenxa ye-obturator emibili efakwe emzimbeni owodwa futhi ahlinzeka ngomsebenzi wokopha ngesistimu yokopha/yokungenisa umoya etholakala phakathi kwama-obturator (imbobo yomzimba nebhola, isango noma ivalvu yenaliti), kusukela ekwakhiweni kwamavalvu ebhola elintantayo, amavalvu e-Med DBB anezakhiwo eziningana ezihlukene.
» Amabhola amiswe kabili ancike ezisekelweni, nasezihlalweni zensimbi ezintantayo noma ezithambile, ivalve yokukhipha inaliti emaphakathi
» Ibanga losayizi ukusuka ku-1/2” kuye ku-2”, osayizi abakhulu ngokuceliwe
» Ibanga Lokucindezela: ukusuka ku-ASME Class 150 kuya ku-ASME Class 2500
» Ububanzi bezinga lokushisa: kusuka ku -46 kuya ku-450
»I-Side Entry Forged Steel Valves
» Ngesicelo, idizayini yokungena okuphezulu
» Ukuncipha kwengcindezi ngevalvu
» I-torque ephansi yokusebenza
» Ukumaka “CE” ngokuhambisana ne-PED Directive 97/23/EC
» Isithukuthezi esigcwele noma Yehlisa isithukuthezi
» Izinhlobo ezihlukene zokuxhuma iziphetho(RF/RTJ) Flanges, Butt weld, Clamp Connection, Socket Welding.
» Ukutholakala okubanzi kwezinto ezihlanganisa imininingwane (i-carbon steel, insimbi engagqwali noma i-Duplex steel ukuze isetshenziswe endaweni ebolayo, insimbi ye-Chrome-Molybdenum alloy yesevisi yezinga lokushisa eliphezulu, njll.
» Izimpahla ezinezakhiwo zokunqanda ukugqwala ngokusho kwe-NACE MR 0175
» Uma ucela, imbongolo yendawo yesihlalo, indawo evalekile, noma ukuvala okuqediwe endaweni emanzi (imbondela eshiselwe ku-inconel 625, Stainless Steel 316 njll., noma i-Electroless Nickel Plating)
»Sifanele isikrufu noma i-actuation yemoto(hydraulic, pneumatic, gas-over-oil noma i-actuator kagesi)
