Vrijstroomafsluiter
Type 2000 / Artikelnr. 2381
Productbeschrijving
Het extern gestuurde vrijstroomventiel bestaat uit een pneumatisch bediende zuigeractuator en een 2-weg-ventielhuis. Afhankelijk van de omgevingstemperatuur is de actuator leverbaar in twee verschillende materialen, PA, PPS. De beproefde zelf instellende spindelafdichting staat borg voor een hoge dichtheid. Het gestroomlijnde 2/2-weg-ventielhuis van roodkoper of fijn gegoten RVS maakt hoge doorstromingswaarden mogelijk. Deze onderhoudsvrije en robuuste ventielen kunnen met een omvangrijk toebehorenassortiment voor positie-indicatie, slagbegrenzing of handnoodbediening worden uitgebreid.
