Valve ea rona e na le botenya bo tloaelehileng ho latela GB26640, e etsa hore e khone ho tšoara khatello e phahameng ha ho hlokahala.
Setulo sa rona sa li-valve se sebelisa rabara ea tlhaho e tsoang kantle ho naha, e nang le rabara e fetang 50% ka hare.Setulo se na le thepa e ntle ea elasticity, e nang le bophelo bo bolelele ba tšebeletso.E ka buleha le ho koaloa makhetlo a fetang 10,000 ntle le tšenyo ea setulo.
Setulo sa valve se nang le 3 bushing le 3 O ring, se thusa ho tšehetsa kutu le ho tiisa ho tiisoa.
'Mele oa valve o sebelisa phofo e phahameng ea sekhomaretsi epoxy resin, e o thusa ho khomarela' mele ka mor'a ho qhibiliha.
Liboutu le linate li sebelisa thepa ea SS304, e nang le bokhoni bo phahameng ba ho sireletsa mafome.
Pini ea li-valve tsa butterfly e sebelisa mofuta oa modulation, matla a phahameng, e thibelang ho roala le khokahano e sireletsehileng.
Sehlahisoa se seng le se seng sa ZFA se na le tlaleho ea thepa bakeng sa likarolo tse kholo tsa valve.
Valve e amohela mokhoa oa ho penta phofo ea epoxy, botenya ba phofo ea tht ke 250um bonyane.'Mele oa valve o lokela ho futhumala lihora tse 3 tlas'a 200 ℃, phofo e lokela ho tiisa lihora tse 2 tlas'a 180 ℃.
Pneumatic actuator e nka sebopeho sa piston e habeli, ka nepo e phahameng le e sebetsang hantle, le torque e tsitsitseng ea tlhahiso.
Teko e Khethehileng: Ho latela tlhoko ea moreki, re ka etsa tlhahlobo efe kapa efe eo u e hlokang.
ZFA Valve e sebetsa ka thata API598 standard, re etsa liteko tsa khatello ea mahlakoreng ka bobeli bakeng sa valve 100%, re fana ka li-valve tsa boleng ba 100% ho bareki ba rona.
'Mele oohle oa li-valve o entsoe ka' mele o nepahetseng oa ho lahla, DI, WCB, Stainless Steel le lisebelisoa tse ling tse ngata, tse nang le ponahalo e phethahetseng, sehlopha ka seng se na le nomoro ea setofo sa eona, ho bonolo ho e fumana bakeng sa tšireletso ea thepa.
Re sebelisa machining a CNC ho sebetsana le disc ea valve, ho laola ho nepahala ha valve ka borona, ho tiisa thepa e ntle ea ho tiisa ho tloha tlase ho ea mocheso o phahameng.
