Product introduction
DPR1 series valves are a compact, high-purity two-stage cylinder regulator with a bundled diaphragm for low-flow toxic, flammable and spontaneous combustion gases. Diffusion-proof metal diaphragm seals ensure gas purity and integrity.
Product characteristics
Maximum inlet pressure 3000 psig / 207 bar
Outlet pressure range: 0-25psig, 0-50psig, 0-100psig and 0-150 psig 0-1.7bar, 0-3.4bar, 0-6.9bar and 0-10.3 bar
Designed to withstand 150% maximum rated pressure
Leak inside: airtight outside: Designed to meet < 2 x 10-8 atm cc/sec He
Operating temperature -40°F to 140°F / -40°C to 60°C
Circulation capacity Cv = 0.05
Maximum operating torque 30 inch-pounds /3.4 nm
Attenuation inlet characteristics 0.06 variation /100 psig inlet, 0.004 variation /6.9 bar inle
Product advantage
Excellent attenuation inlet characteristics: 0.06/100 psig or 0.004/6.9 bar inlet variation
Positive seal design
The two diaphragms of the captured bonnet port have a gyroscope structure to improve accuracy and sensitivity
The metal-to-metal diaphragm is sealed with the valve body to minimize diffusion
The connection of the diaphragm to the valve enhances the integrity of the seat seal
Main use
Optional outlet pressure range: 0-25psi, 0-50psi, 0-100psi, 0-150psi
