I-valve yebhola ye-pneumatic actuatediyi-valve ezenzakalelayo.Ukusebenzisa umoya ohlanzekile njengomthombo wokushayela ukushayela i-valve ukuvula noma ukuvala.Izinzuzo zayo izindleko eziphansi, ukuvikela ukuqhuma, ukuvikelwa kwemvelo, kanye nesivinini sokushintsha ngokushesha.Ingasetshenziswa ezimbonini ezihlukahlukene, ezifana nokwelashwa kwamanzi angcolile, ukwelashwa kwegesi engcolile, ukulahlwa kukadoti, amapayipi okuphuza umoya, ukwakha umkhumbi nokunye.
Kulesi sihloko, sizokwethula imihlahlandlela emi-3 yokukhetha i-valve yebhola yomoya.Ngethemba ukukusiza ukuthi ukhethe i-valve efanele yephrojekthi yakho futhi usize iphrojekthi yakho isebenze kangcono.

1. I-Actuator

Ama-actuator e-pneumatic ahlukaniswe abe izinhlobo ezimbili ngokuya ngokucaciswa kwawo, enye iwuhlobo lokubuya kwentwasahlobo, kanti enye iwuhlobo olusebenza kabili.
Ama-actuator ohlobo lwe-Spring return awumoya ongavuleka, azovalwa ngokuzenzakalela uma umoya uphazamisekile.
Ama-actuator ohlobo olusebenza kabili avulwa emoyeni, avuleke.
Ungakhetha uhlobo olulungile lwe-actuator yomoya ngokwezidingo zakho.

2. I-Torque Range

Izitayela ezihlukene zama-actuator we-pneumatic zinezigaba ze-torque ezihlukene.
I-AT series actuator enetorque isuka ku-5.7Nm iye ku-4,678Nm
I-AW series actuator enetorque isuka ku-185Nm iye ku-157,300Nm
I-actuator yohlobo lwe-Scotch Yoke ene-torque isukela ku-500Nm iye ku-40,000Nm
Ukukhetha i-actuator enobubanzi be-torque obufanele kungaqinisekisa ukuvulwa nokuvalwa kwe-valve, ukuze kugwenywe ukuthikameza ukusebenza kahle kokukhiqiza ngoba ayikwazi ukuvulwa noma ukuvalwa.

3. I-valve yebhola

I-COVNA inezinhlobonhlobo zezinhlobo zamavalvu ebhola, wonke lawo angamazinga e-ISO5211, angaxhunywa kahle nama-actuator womoya.
Ngokwendlela yokuxhuma, singahlinzeka ngohlobo lwentambo, uhlobo lwe-flange, uhlobo lwe-clamp, uhlobo lwe-welding kanye nohlobo lwenyunyana ephindwe kabili ukuze kuhlangatshezwane nezidingo zakho ezihlukene zamapayipi.
Ngokwemodi yokugeleza, singakunikeza i-valve yebhola yezindlela ezingu-2, i-valve yebhola yezindlela ezingu-3 (imbobo ye-T noma imbobo ye-L) kanye ne-valve ye-4-wayball (X Port) ukuze ukhethe ukuhlangabezana nezidingo zakho ezihlukahlukene zokugeleza.
Ngokusho kokuqukethwe, singakunikeza insimbi engagqwali, i-WCB, ipulasitiki nezinye izinto ongakhetha kuzo.
Ngaphezu kwalokho, singanikeza uhlobo lwenjongo evamile, uhlobo lokushisa eliphezulu, uhlobo lomfutho ophezulu, uhlobo olumelana nokugqwala kanye nohlobo lwebanga lokudla lwezinhlelo zakho zokusebenza ezikhethekile.

Nawa amathiphu angu-3 wokukhetha i-COVNA pneumatic actuated ball valve futhi uma udinga ulwazi olwengeziwe noma imibuzo mayelana nama-valve, zizwe ukhululekile ukusithinta ku-sales@covnavalve.com
