LINE
REGULATORS
Models AG3820, AG3830
Ultra High Purity, High Flow Line Regulators
Capable of flow rates up to 1500 scfh at inlet pressures of 500 psig, these line regulators are ideal for high flow delivery systems requiring high
leak integrity and guaranteed gas purity levels. Model AG3820 is suitable for non-corrosive service, while Model AG3830 is designed for corrosive gas applications.
Standard
Features
- Stainless Steel Diaphragm minimizes diffusion of air into regulator and eliminates “off gassing” associated with elastomeric diaphragms,
thus maintaining gas purity.
- High Purity Regulator Design permits vacuum purging of regulator.
- In-line Porting permits direct installation of regulator in piping system.
- 21⁄2" Gauge reads easily for more precise settings.
- Threaded Holes in Rear of Regulator permit front panel mounting.
Optional Features
- Mounting Ring permits regulator to be panel mounted (AG3830 Model only)
- Compression Fittings installed in inlet and outlet ports allow connection to 1⁄4" tubing.
- Regulator mounting plate allows for easy mounting of regulator to wall or panel.
- Internal (Inboard) Helium Leak Test and Test Report determines inboard leak rate of gas from regulator to atmosphere; test report certifies leak rate
of less than 2 x 10–8 sccs air equivalent.
- External (Outboard) Helium Leak Test and Test Report determines outboard leak rate of gas from regulator to atmosphere; test report certifies leak
rate of less than 5 x 10–7 sccs air equivalent.
