HP 455 series
Higher flow capacity regulator, particularly suited for use with more corrosive gases and strongly oxidising gases in process applications due to the materials of construction and the positive shut off features of the control valve. Nickel-plated brass body, with hastelloy internals and monel gauges.
Features
- Nickel plated brass body with stainless steel diaphragm , hastelloy nozzle and monel gauges for high corrosion-resistance
- High load marginal seat spring for positive shut-off and protection against downstream overpressure
- High flow capacity
Standard supply includes:
- Inlet connection and gauge
- Outlet gauge, outlet valve, and compression fitting
Specification
• Body: electroless, nickel-plated forged brass
• Seat & seals: PTFE
• Nozzle: Hastelloy®
• Diaphragm: 316L stainless steel
• Gauge internals: Monel
• Maximum inlet pressure: 207 bar or as limited by the inlet gauge/components
• Flow rate data: Cv = 0.2
• Operating temperature: -40°C to +60°C
• Weight: 3.5kg (approx)
| Model required | Outlet pressure bar (psi) | Outlet gauge bar (psi) | Relief Valve Setting (bar) |
|---|---|---|---|
| HP455 : 2.8 bar | 0 – 2.8 (0-40) | 0-4 (0 – 60) | None |
| HP455 : 8 bar | 0 – 8 (0-120) | 0 -14 (0 – 200) | 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), Lever valve cross purge |
| Filter | Particle removal down to 0.1 micron | FBT (inlet), FBL (outlet) |
| Excess flow valve | Will shut off system when flow rate exceeds preset level | EFV190 |
How to Order
When ordering it is important to specify the gas or mixture to be used.
- select model e.g. HP455:2.8bar, HP455:8bar
- select inlet gauge e.g. GG (300 bar), GL(70 bar), GE (28 bar), GU (14bar)
- select inlet connection e.g. BS6, DIN8 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 options e.g. filters (FBL)
