Linde North America, Inc. Two Stage High Purity Regulators F7140 Series

The F7140 Series two stage, high purity regulators are designed for non-corrosive analytical and process applications requiring precise, stable delivery pressure control. The two stage design yields a delivery pressure change of less than 0.04/100 psi inlet change. The regulators' convoluted stainless steel diaphragms provide excellent regulating characteristics and allow for internal purging. The metal-to-metal diaphragm seal prevents contamination by eliminating the need for a soft seal, and provides a leak-rate design of less than 2 x 10-8 ccs helium. This minimizes cleanup time when purging and yields lower residual contaminant levels.
