R27/Manostat Precision Pressure Regulator Range

The Manostat Precision Pressure Regulator Range are designed for critical pressure control applications and have demonstrated outstanding reliability 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. The base unit has been developed to be operated by various mechanisms making it ideal for many different applications. Versions include: handwheel, plunger, lever operated and volume boosting air relay.


R27 / Manostat Manually Operated

These Manostats are available as Handwheel or Volume Boosting Air Relay operation options.

» Ideal for for dead-end (closed load) conditions and can be supplied on its own or with a visual display dial.
» Precise regulation of pressures up to 10 bar
» Control relatively independent of flow and temperature
» Ideal for dead end applications
» DIN/Dial versions for visual indication of set pressures.
» Low Air Consumption


Industry:

Railway Pantograph system and Trams

Solution:

The Manostat controls the vertical pressure between the pantograph and the cable.

This requires rapid operation (high flow) as well as stability across a wide temperature range

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).

•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 % output change for 1bar/15psi supply Accuracy pressure change at mid-range output: 0.1%

(0.14bar/2 to 25psi), 0.05% (0.14-4bar/2 to 60psi), 0.02% (0.14-8bar/2 to 120psi)

•Sensitivity Better than 0.3mbar (0.005psi)

•Hysteresis and Typically less than 0.05% setting at mid-range

Repeatability

•Temperature Typically better then 1% change of full span between -20C and +70C

Effect

•Connections 1/4” NPT female standard (plus two integral 1/4” NPT gauge ports); others on request


Physical

•Operating Temperature -20C to +70C

•I.P. Rating IP65

•Vibration The unit is unaffected by moderate vibration

•Material of Construction Zinc diecasting passivated and epoxy painted, Beryllium copper capsule; Nitrile diaphragms


Model Types

•Handwheel: Basic manostat unit with pressure adjusting handwheel; mounting in any attitude, integral mounting nutsupplied

•Dial manostat: Manual pressure loading unit combining a manostat regulator with a 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

Note: a small pressure (<2psig, 0.14bar) will show at the lower end of dial manostats gauge scale (due to regulator

servo operation)
