2/2-vägs direktstyrd proportionalventil, standard-utförande
Typ 2875 / Artikelnr. 367840
Artikelbeskrivning
Direktstyrda proportionalventilen typ 2875 kan användas som styrventil för processtyrning. Tack vare den elastomeriska sätestätningen sluter ventilen helt tätt (integrerad låsfunktion). Ventilens manöverspak är friktionsfritt monterad vilket ger extraordinär kontroll. Denna ventil är särskilt lämpad för krävande styruppgifter (höga intervall, torra gaser m.m.).
