Airgas Model C445F Stainless Steel High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Threadless Seat

Product Description

This series of 316 stainless steel two-stage high-purity regulators is designed for non-corrosive analytical, mildly corrosive 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 Hastelloy C-22 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.

Features

• Rugged Brass Piston provides increased safety and reliability at high delivery pressures. Bonnet Vent Ports (with optional bonnet vent adapters) allow venting of hazardous gases in the event of sensor O-ring failure. Standard Threaded Bonnet (with optional collar mount nuts) permits panel mounting. Ultrasonic Cleaning allows high-purity gas handling without costly pre-cleaning.

Product Details

Designed for a wide range of pressure settings, these single-stage regulators are recommended for use in petroleum field applications, research laboratories for hydrogenation, catalytic reduction, accelerated age testing, calorimetric testing, component testing, and pressure testing applications. These regulators feature a rugged brass piston, which provides increased safety and reliability at high delivery pressures. A 25-micron inlet filter protects internal components..
