Sædeventiler: Anvendelsesområder og brancher

Sædeventiler er særdeles velegnede til hurtige aktiveringer, høje temperaturer og regulering. De anvendes ofte til dampstyring og vandbehandling. De vigtigste anvendelsesområder er mange forskellige applikationer i industrielle processer, men også i sterile og hygiejniske applikationer inden for lægemidler, fødevarer og bioteknologi.

 

Sædeventiler: Ventilprincip

Sædeventiler er særdeles velegnede til styring og regulering af mekanisk rene, kemisk neutrale og svagt aggressive væsker, gasser og dampe.

Her trykker en planpakning, der som regel består af PTFE, mod et tætningssæde og spærrer på denne måde for volumenstrømmen. Man skelner mellem ligesæde- og skråsædeventiler. Ligesædeventilen anvendes ofte ved større indvendige diametre og fås også i en 3-vejs-udførelse, som gør den meget god til blande- og omskiftningsopgaver. Ligesædeventilen er også den foretrukne ved maksimal belastning af ventilen fra høje flowhastigheder og hyppig efterregulering på grund af den mere regelmæssige kraftpåvirkning af ventilspindlen. Skråsædeventiler er lettere og mere kompakte og har en forholdsvist højere flow-værdi (Kvs-værdi). Selv standardudførelserne er egnede til medietemperaturer op til 180 °C og driftstryk op til 40 bar. I modificerede udførelser er der endda mulighed for temperaturer op til 300 °C. Sædeventilernes konstruktionsmæssigt gode mekaniske egenskaber gør dem især egnede til hyppige omskiftninger samt tappe- og doseringsopgaver. De er også det bedste valg til generering og fordeling af industri- og sterildamp.

Til det nævnte ventilprincip tilbyder GEMÜ mange typer tilpasset tilbehør til automatisering og procesoptimering. Elektriske indikatorer, stillings- og procesregulatorer samt sensorteknik og måleapparater opbygges, indstilles og integreres hurtigt i den eksisterende processtyringsteknik.
