VAREC 2010B/2020B PRESSURE AND VACUUM RELIEF VALVES
www.emerson.comThe mixed pressure/vacuum set ranges , 0204 and 0402 (Low pressure/high vacuum and high pressure/low vacuum) use heavier pallets and therefore have higher low set range minimums. For these cases, add the applicable value from the table (right) to the low set range minimum. (This increase does not apply for 10” and 12” 2011B/2021B.)
