Installation Guidelines

• Sarudzo:Match valve mhando, saizi, uye zvinhu kune midhiya zvivakwa (semuenzaniso, tembiricha, kudzvanywa) kudzivirira pasi- kana kupfuura-saizi.
• Environment:Isa kure nechiedza chezuva, kupisa, kana kutenheka; simudza ma actuators vertically kuitira mvura inyore.
• Piping:Rongedza vharafu negwara rekuyerera (ona museve wemuviri); kuchenesa nzvimbo dzekuisa chisimbiso uye simbisa mabhaudhi zvakaenzana pazvisungo zveflanged.
• Air Supply:Shandisa mhepo yakasefa, yakaoma ine mitsetse yakatsaurirwa; chengetedza kudzvanywa kwakagadzikana mukati meiyo actuator ratings.
• Mabatirwo emagetsi:Wire positioners/solenoids nemazvo ne ground shielding kudzivirira kupindira; test valve operation mushure mekuiswa.

Maintenance and Care

• Kuchenesa:Pukuta mavharuvhu mwedzi wega wega kubvisa guruva, mafuta, uye zvakasara; tarisa panzvimbo dzekuvhara.
• Lubrication:Gadzirisa madzinde uye zvikamu zve actuator mwedzi yese 3-6 nemafuta akakodzera (semuenzaniso, giredhi rekushisa).
• Seal Inspection:Tarisa zvigaro zvevharuvhu uye macores nguva nenguva nekuda kwekudonha; shandura zvisimbiso (O-mhete) sezvinodiwa.
• Accessory kuchengetedza:Ongorora zvinzvimbo, solenoid mavharuvhu, uye mafirita mwedzi 6-12 yega yega; yakachena sefa zvinhu uye recalibrate positioners.
• Kugadzirisa dambudziko:Gadzirisa zvinhu zvakajairika sekunamira (marara akacheneswa), kuita zvishoma nezvishoma (tarisa kudzvanywa kwemhepo), kana kubuda (simbisa mabhaudhi / tsiva zvisimbiso) nekukasira.
• Kuchengeta:Simbisa mavharuvhu asingashandiswe, depressurize actuators, uye chengetedza munzvimbo dzakaoma; tenderera mavharuvhu cores dzimwe nguva kudzivirira kunamatira chisimbiso.
