HP1700 Series
High purity two stage regulator available in brass or stainless steel, for use with non corrosive and mild corrosive gases and mixtures up to N6.0 purity. Advanced features make it suitable for the most demanding analytical requirements. This regulator can withstand vacuum applied to evacuate the system. Accepting inlet pressures up to 230bar (with a choice of gauges to suit lower cylinder pressures), it has a choice of delivery pressure ranges from 0 – 0.7bar, to 0 – 17bar.
Features
- Bar stock brass or stainless steel body
- Hastelloy diaphragm with metal to metal seal for high leak integrity
- Precise, accurate pressure control
- Quick purging due to low internal volume and internally threadless nozzle assembly
- 10 micron inlet filter for increased reliability
- Bonnets threaded for panel mounting
- Standard supply includes:
Inlet connection and gauge
Outlet gauge, outlet valve, outlet relief valve and compression fitting

| Filter | Particle removal down to 0.3 micron | FBT(inlet), FBL (outlet) |
How to order
ALWAYS specify gas or mixture to be used:
- select model e.g. HP1700, HP1701
- select material e.g. brass, stainless steel
- select inlet gauge: to match cylinder or line pressure e.g. GG (300 bar), GL (100 bar brass, 66 bar stainless steel), E (26 bar), U (13 bar)
- select inlet connection e.g. BS3, DIN 1
- select any inlet options e.g. body purge, cross purge, filters (pressure rating dependent)
- select outlet connection e.g. 1/4" compression fitting (standard), other fittings are available
- select any outlet options e.g. filters
