These brass, single-stage, high-purity regulators are recommended for non-corrosive analytical and process applications where precise flow control is not critical. A specially designed, convoluted, stainless steel diaphragm with metal to metal seals provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. These regulators come with a CGA-nipple that has a special high-purity, non-lubricated check valve incorporated into nose and prevents air and contaminants from entering the gas stream during cylinder change out. This creates consistencies in processes and extends column life in GC applications. Each regulator is capable of withstanding an internal vacuum and is provided with a diffusion-resistant, diaphragm packless outlet valve to maintain system purity. The optional bonnet vent adapter allows for the venting of hazardous gases in the event of diaphragm failure.
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.
