Pneumatic actuated ball valveke valve e itekanetseng.Ho sebelisa moea o hloekileng e le mohloli oa ho khanna ho khanna valve ho bula kapa ho koala.Melemo ea eona ke theko e tlase, bopaki ba ho phatloha, ts'ireletso ea tikoloho, le lebelo la ho fetoha ka potlako.E ka sebelisoa liindastering tse fapa-fapaneng, tse kang ho hloekisa metsi a litšila, ho hloekisa khase ea litšila, ho hloekisa litšila, liphaephe tsa ventilation, ho haha ​​​​likepe joalo-joalo.
Sehloohong sena, re tla u tsebisa litataiso tse 3 tsa ho khetha valve ea bolo ea moea.Ke tšepa ho u thusa ho khetha valve e nepahetseng bakeng sa morero oa hau le ho thusa morero oa hau hore o tsamaee hantle.

1. Sebapali

Li-actuator tsa pneumatic li arotsoe ka mefuta e 'meli ho ea ka litlhaloso tsa tsona, e' ngoe ke mofuta oa ho khutla ha selemo, 'me e' ngoe ke ea mefuta e 'meli.
Li-actuator tsa mofuta oa ho khutla ha selemo ke moea o ka buloang, ebe o tla koala hang ha moea o sitisoa.
Li-activator tsa mefuta e 'meli li na le moea ho bulela, moea ho tima.
U ka khetha mofuta o nepahetseng oa pneumatic actuator ho latela litlhoko tsa hau.

2. Torque Range

Mefuta e fapaneng ea li-actuator tsa pneumatic e na le mefuta e fapaneng ea torque.
AT letoto la actuator e nang le torque e tlohang ho 5.7Nm ho isa 4,678Nm
AW series actuator e nang le torque range ho tloha 185Nm ho isa 157,300Nm
Sesebelisoa sa mofuta oa Scotch Yoke se nang le torque ho tloha ho 500Nm ho isa 40,000Nm
Ho khetha actuator e nang le sebaka se loketseng sa torque ho ka netefatsa ho bula le ho koaloa ha valve, e le ho qoba ho ama katleho ea tlhahiso hobane e ke ke ea buloa kapa ea koaloa.

3. Belofo ea bolo

COVNA e na le mefuta e fapaneng ea li-valve tsa bolo, tseo kaofela e leng maemo a ISO5211, a ka hokahanngoang hantle le li-actuator tsa moea.
Ho latela mokhoa oa ho hokahanya, re ka fana ka mofuta oa khoele, mofuta oa flange, mofuta oa clamp, mofuta oa welding le mofuta oa bonngoe ba habeli ho fihlela litlhoko tsa hau tse fapaneng tsa liphaephe.
Ho ea ka mokhoa oa ho phalla, re ka fana ka 2-way ball valve, 3-way ball valve (T port kapa L port) le 4-way ball valve (X Port) hore u khethe ho finyella litlhoko tsa hau tse fapaneng tsa phallo.
Ho ea ka thepa, re ka fana ka tšepe e sa hloekang, WCB, polasetiki le lisebelisoa tse ling tseo u ka li khethang.
Ho feta moo, re ka fana ka mofuta oa sepheo se akaretsang, mofuta oa mocheso o phahameng, mofuta oa khatello e phahameng, mofuta o hananang le kutu le mofuta oa boemo ba lijo bakeng sa lits'ebetso tsa hau tse khethehileng.

Malebela ke ana a 3 a ho khetha valve ea COVNA pneumatic actuated ball mme haeba o hloka lintlha tse ling kapa lipotso mabapi le li-valve, ikutloe u lokolohile ho ikopanya le rona hosales@covnavalve.com
