U.S. Patent No. 5,358,004
The R-800 series regulators offer high performance in a compact size. 1/8-27 NPT ports allow the use of a wide range of fittings for design flexibility.
FEATURES:
Twenty turn hysteresis free adjustment allows pressure settings to 1″ WC resolution.
Four adjusting styles allow maximum design flexibility. The non-rising stem is available with an attractive knob, or plain, allowing installation of OEM knobs. Also available is a flush adjusting shaft, for applications where pressure settings are changed less frequently. Factory pre-set “tamperproof” models are also available. (See drawings)
Mounting options include panel mount, through a 9/16″ hole (nut included), and base mount, through 4 holes 0.125″ dia. (See drawings)
Plastic construction – corrosion resistant wetted materials.
High accuracy – Low effect of supply variation on output.
Low cost – Perfect for OEM applications.
Applications:
Medical Equipment
- Oxygen Concentrators
- Ventilator / Respirators
- Nebulizers
Air Bearings
HVAC Systems
Custom Machinery
Robotics
Options

Specifications
| R-800 Series | |
|---|---|
| REGULATOR TYPE | Constant Bleed, Relieving |
| WETTED MATERIALS | Polysulfone, Buna-N, EPDM, Acetal, Polyurethane, Stainless steel |
| SUPPLY CONSUMPTION | < 9 SCIM (150 cc/min) @ 30 PSI (207 kPa) supply < 21 SCIM (350 cc/min) @ 100 PSI (689 kPa) supply |
| MAX SUPPLY | 150 PSI (1.03 MPa) |
| TEMPERATURE RANGE | 40° – 150° F (4° – 66° C) |
| EFFECT OF SUPPLY VARIATION | < 0.05 PSI (0.35 KPa) per 10 PSI (68.9 kPa) supply change when dead-ended |
| REPEATABILITY | < +/- 0.1 PSI (0.69 kPa) when supply is removed and re-applied |
| SENSITIVITY | 1″ H2O (0.25 kPa) |
| MAXIMUM FLOW | 2.5 cu.ft./min. (70 LPM) |
| RELIEF CAPACITY | 0.5 cu.ft./min. (14 LPM) with outlet 5 PSI (34.5 kPa) above set-point |
| RECOMMENDED FILTRATION | 5 micron |
| R-810 Series | |
| REGULATOR TYPE | Non-bleed, non-relieving
Note: R-810 series regulators are not recommended for dead-end, no flow applications. A downstream relief of 5 cc/min is recommended. |
| REPEATABILITY | < +/- 0.25 PSI (1.72 kPa) when supply is removed and re-applied |
| MAXIMUM FLOW | 1.0 cu.ft./min. (28 LPM) |
| EFFECT OF SUPPLY VARIATION | < 0.1 PSI (0.69 kPa) per 10 PSI (68.9 kPa) supply change |
| All other specifications remain the same as the R-800 Series | |
| R-820 Series | |
| REGULATOR TYPE | Non-bleed, relieving |
| SUPPLY CONSUMPTION (see note) | < 0.3 SCIM (5 cc/min.) |
| REPEATABILITY | < +/- 0.25 PSI (1.72 kPa) when supply is removed and re-applied |
| EFFECT OF SUPPLY VARIATION | < 0.1 PSI (0.69 kPa) per 5 PSI (34.5 kPa) supply change |
| SENSITIVITY | 2″ H2O (0.5 kPa) |
| All other specifications remain the same as the R-800 Series
Note: R-820 series regulators have “near zero” bleed to atmosphere under normal operating conditions. Should any overshoot, or downstream pressure increases occur, the unit will relieve only what is necessary to stabilize the pressure setting. |
