R27 - Manostat Precision Pressure Regulator Series
Manually/Mechanically Operated


Features

 Reliable, durable
 Precise regulation
 Excellent setting sensitivity
 High relief capability
 Versatile design for varied applications General Description

The manostat precision pressure regulator series are designed for critical pressure control applications and have demonstrated outstanding reliablility and durability in many thousands of applications worldwide. It is suitable for dead-end (closed load) conditions and can be supplied on its own or with a visual display dial

Other versions include; plunger, lever operated and volume boosting air relay.

Technical Data
Pneumatic
*Output Signal See ordering information. Pressure range can be limited by resetting the locknuts provided
*Air Supply Oil free, dry air or other dry gases, filtered to better than 25 microns; at least 0.2bar (3psig) above output pressure to a maximum of 10bar (150psig, 1000kPa)
*Flow Capacity Up to 300nl/min (10scfm). High relief version available for applications requiring a rapid exhaust
*Air Consumption 0.2 l/min (0.006scfm) at 1bar (15psig);
0.3 l/min (0.01scfm) at 1.7bar (25psig);
0.6 l/min (0.02scfm) at 4bar (60psig);
1.2 l/min (0.04scfm) at 8bar (120psig);
(typical values at maximum supply pressure)
*Response Time less than 0.2 seconds for 50% load change
*Regulation Accuracy % output change for 1bar/15psi supply pressure change at mid-range output; 0.1% (0.14bar/2-25psi), 0.05% (0.14-4bar/2-60psi), 0.02% (0.14-8bar/2-120psi)
*Sensitivity Better than 0.3mbar (0.005psi)
*Hysteresis and Repeatability Typically less than 0.05% setting at mid-range
*Temperature Effect Typically better than +/-1% change of full span between -20°C and +70°C
*Connections 1/4" NPT female standard (plus two integral 1/4" NPT gauge ports); others on request
Model Types
*Handwheel Basic manostat unit with pressure adjusting handwheel; mounting in any attitude, integral mounting nut supplied
*Dial manostat Manual pressure loading unit combining a manostat regulator with 4" diameter gauge
*DIN manostat As above but with a DIN standard pressure gauge
*DMW Weatherproof version of dial manostat with 100mm diameter gauge; pneumatic connections taken to lower face of casing; surface or post mounting (yoke supplied suitable for a 50mm/2" diameter post); casing is polycarbonate, grey finish to IP55
*Volume Boosting Air Relay (manual bias) Remote control of regulated pressures is possible with minimal air usage; positive or negative bias between pilot signal and regulated pressure can be set up of up to 2bar/30psig
Physical
*Operating Temperature -20°C to +70°C
*IP Rating IP65
*Vibration The unit is unaffected by moderate vibration
*Material of Construction Zinc diecasting passivated and epoxy painted. Berylium copper capsule; Nitrile diaphragms
note: a small pressure (<2psig, 0.14bar) will show at the lower end of dial manostats gauge scale (due to regulator servo operation)
