- This series of stainless steel two-stage high-purity regulators is designed for non-corrosive analytical, mildly corrossive and process applications requiring precise, stable delivery pressure control. The two-stage design yields a delivery pressure change of less than 0.01/100 psi inlet change. Convoluted stainless steel diaphragms provide excellent regulating characteristics and allow for internal vacuum 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 in vacuum purging and yields lower residual contaminant levels. A diaphragm packless outlet valve with a 1/4" compression-tube fitting is provided for flow control and to maintain system purity. Captured bonnet ports with optional vent Adapters are standard on both stages and allow the venting of hazardous gases in the event of diaphragm failure. These regulators are ultrasonically cleaned for the most demanding high-purity service.
- Convoluted Hastelloy C22 Diaphragms - provide superior leak integrity without contamination from a non-metallic liner or seal.Bonnet Vent Ports (with optional bonnet vent Adapters) - allow venting of hazardous gases in the event of diaphragm failureStandard Threaded Bonnet (with optional collar-mount nuts) - for easy panel mounting.Diaphragm Packless Valve (with 1/4" compression fitting) - promotes system purity.Threadless Seat Design - provides longer regulator life.
