HP1700T series
HP1700T is a two-stage, stainless steel regulator with tied diaphragm design for positive shut off, reducing the risk of overpressure on the outlet. High specifications make this suitable for N6.0 gases. The tied diaphragm feature makes this regulator particularly suited to gases with more demanding properties – eg highly corrosive gases and gases with high levels of toxicity. Accepting inlet pressures up to 230bar, it has a choice of delivery pressure ranges from 0 – 2bar, to 0 – 5bar.
Features
- Stainless steel body with smooth surface finish for minimal particle generation
- Tied diaphragm for positive shut-off and metal to metal seal for high leak integrity
- Precise pressure control
- Threaded bonnets for panel mounting
- Quick purging due to low internal volume and internally threadless nozzle assembly
- Standard supply includes:
Inlet connection and gauge
Outlet gauge, outlet valve, and compression fitting

| Model | Outlet Pressure Bar (psi) | Outlet Gauge Bar (psi) | Relief Valve Setting Bar |
|---|---|---|---|
| HP1700T | 0-2 (0-30) | Vac – 4 (vac – 60) | None |

| Option | Use | Models available |
|---|---|---|
| Purge assembly | To purge toxic, corrosive or high purity gases from the regulator body to prevent accidental exposure and maintain process gas purity | Body purge (P), Cross purge (CPS), Lever valve cross purge (LPS) |
| Relief valve | For system overpressure protection | Relief valve (outlet) |
| Filter | Particle removal down to 0.3 micron | FBT (inlet), FBL (outlet) |
| Excess flow valve | valve Will shut off system when flow rate exceeds preset level | EFV190 |
How to order
ALWAYS specify gas or mixture to be used:
- select model e.g. HP1700T, HP1701T
- select inlet gauge e.g. GG, GL (300 bar), E (70 bar)
- select inlet connection e.g. BS4, DIN1 etc.
- select any inlet options e.g. cross purge, body purge, excess flow valve
- select outlet connection e.g. 1/4" compression fitting (standard)
- select any outlet connections e.g. relief valve, filters (FBL)
