3370 Series Micro VOC Regulators – Stainless Steel

The 3370 Series Pressure Regulator is a compact single stage regulator with new patent pending technology that enables the performance of a two stage regulator. The 3370 Series is a diaphragm sensed, single stage regulator capable of significantly reducing the decaying inlet characteristic (supply pressure effect) that is typically characteristic of single stage regulator designs. The result: the stable delivery pressure of a two stage regulator in the compact design of a single stage. The 3370 Series is elastomer free with a stainless steel body, stainless wetted parts, an Elgiloy® diaphragm, Teflon® seals, and small internal volume for compatibility with high purity applications. The 3370 Series is fitted with an Elgiloy diaphragm that is conducive to high cycle applications and wide temperature swings.
