Frequently Asked Questions
1. What is the maximum inlet pressure for this regulator?
The maximum rated inlet pressure is 3000 psig (207 bar), with a design proof pressure of 150% of the maximum rating.
2. Which materials are used for the diaphragm construction?
The regulators utilize Hastelloy® C276 for the diaphragm to ensure excellent corrosion resistance and durability.
3. Is this regulator suitable for toxic or flammable gases?
Yes, the tied diaphragm design is specifically engineered for safe handling of toxic, flammable, and pyrophoric gases at low flow rates.
4. What is the standard leak rate for these units?
The external leak rate is designed to meet < 2 x 10-8 atm cc/sec He, while the atmosphere leak rate is 1×10-8 Mbar I/S He.
5. What industries typically use these UHP regulators?
These are primarily used in semiconductor manufacturing, photovoltaic production, oil and gas processing, and analytical laboratories.
6. Can the outlet pressure be customized?
Yes, multiple outlet pressure ranges are available including 0-25psi, 0-50psi, 0-100psi, and 0-150psi to suit specific application needs.
