Constructed from 100% high-purity PFA and PTFE wetted parts, Furon UPRM Pressure Regulators are suitable for use with ultrapure, harsh, or aggressive chemicals commonly found in the Semiconductor industry, or any other applications requiring high purity and/or high chemical resistance. A modified PTFE isolation diaphragm protects the actuator components from the process media, assuring no possibility of contamination from metal elements.
