Pneumatic actuated mpira valvendi valve automatic.Kugwiritsira ntchito mpweya woyera ngati gwero loyendetsa galimoto kuti valavu itsegule kapena kutseka.Ubwino wake ndi wotsika mtengo, wosaphulika, chitetezo cha chilengedwe, komanso kuthamanga kwachangu.Itha kugwiritsidwa ntchito m'mafakitale osiyanasiyana, monga kuthira madzi otayira, kuthira gasi, kuthira zinyalala, mapaipi opumira mpweya, kupanga zombo ndi zina zotero.
M'nkhaniyi, tikuwonetsani malangizo a 3 posankha valavu ya mpira wa pneumatic.Ndikuyembekeza kukuthandizani kusankha valavu yoyenera ya polojekiti yanu ndikuthandizira polojekiti yanu kuyenda bwino.

1. Woyendetsa

Ma actuators a pneumatic amagawidwa m'mitundu iwiri molingana ndi zomwe amafotokozera, imodzi ndi mtundu wobwerera masika, ndipo inayo ndi yochita kawiri.
Ma actuators amtundu wa Spring Return ndi mpweya woti atseguke, kenako amatseka pomwe mpweya wasokonezedwa.
Ma actuators amtundu wa Double actuator amakhala ndi mpweya, wothimitsidwa.
Mutha kusankha mtundu woyenera wa pneumatic actuator malinga ndi zosowa zanu.

2. Torque Range

Mitundu yosiyanasiyana ya ma pneumatic actuators imakhala ndi ma torque osiyanasiyana.
AT series actuator yokhala ndi torque kuyambira 5.7Nm mpaka 4,678Nm
AW series actuator yokhala ndi torque kuyambira 185Nm mpaka 157,300Nm
Mtundu wa Scotch Yoke actuator wokhala ndi torque kuyambira 500Nm mpaka 40,000Nm
Kusankha chowongolera chokhala ndi ma torque oyenerera kumatha kuonetsetsa kutsegulidwa ndi kutseka kwa valavu, kuti mupewe kusokoneza magwiridwe antchito chifukwa sichingatsegulidwe kapena kutsekedwa.

3. Vavu ya mpira

COVNA ili ndi mitundu yosiyanasiyana ya mavavu a mpira, onse omwe ali muyeso wa ISO5211, omwe amatha kulumikizidwa bwino ndi makina oyendetsa pneumatic.
Malinga ndi njira yolumikizira, titha kupereka mtundu wa ulusi, mtundu wa flange, mtundu wa clamp, mtundu wa kuwotcherera ndi mtundu wa mgwirizano wapawiri kuti mukwaniritse zosowa zanu zamapaipi osiyanasiyana.
Malingana ndi kayendetsedwe ka kayendetsedwe kake, titha kupereka valavu ya mpira wa 2, 3-way mpira valve (T port kapena L port) ndi 4-way ball valve (X Port) kuti musankhe kukwaniritsa zosowa zanu zosiyanasiyana.
Malinga ndi nkhaniyi, titha kupereka zitsulo zosapanga dzimbiri, WCB, pulasitiki ndi zinthu zina zomwe mungasankhe.
Kuphatikiza apo, titha kukupatsirani mtundu wanthawi zonse, kutentha kwakukulu, mtundu wothamanga kwambiri, mtundu wosamva dzimbiri ndi mtundu wamagulu azakudya pazogwiritsa ntchito mwapadera.

Nawa maupangiri atatu pakusankha valavu ya mpira ya COVNA pneumatic actuated ndipo ngati mukufuna zambiri kapena kufunsa za mavavu, omasuka kutifunsasales@covnavalve.com
