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 Mechanically Operated

Options include Plunger, Lever and Volume Boosting Air Relay operation.

» Control relatively independent of flow and temperature.
» Precise regulation of pressures up to 10 bar
» Ideal for dead end applications
» Plunger/lever operation options available
» High relief capability
» Pressure range can be limited by resetting the locknuts provided
» A high relief version is avaiable for applications requiring a rapid exhaust.


Non extensive list of available models (all of the following are suitable replacement units for model starting with "53"): 180100R, 180200R, 180400R, 190100R, 190400R


Industry:

Textiles, Railway, Laboratory Equipment, paper processing. Open Loop Regulator Designed for applications where standard regulators are not sufficient.

Solution:

The Manostat controls the position of a Conveyor belt. The combination of a handwheel and a lever controlled unit compensate for any lateral deviation of the belt. As the belt slips to the right the lever operated Manostat increases the cylinder pressure which forces the belt back to its central position.

TECHNICAL DATA

Pneumatic

•Output Signal See ordering information.

Minimum outlet pressure 0.1-0.14bar (1.5-2psig). 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 See ordering information

•Response Time less than 0.2 seconds for 50% load change

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

information

•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 available on request


Physical

•Operating Temperature -20C to +70C

•I.P. Rating IP65

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


Model Types


Plunger Operated:

•Dome fitting Direct linear movement in line with the manostat capsule axis changes the regulated pressure

•Clevis fitting Sinusoidal motions to vary the regulated pressure

Plunger force: The force required to operate these instruments will be dependent on pressure range and adjustment and

can be expected to be between 4 and 30N.

Pre-travel on all instruments allows continuous contact with the operating cam outside of range.

Nominal Range Travel (10% manufacturing tolerance); See ordering information


Lever Operated:

Lever mechanism allows the manostat to operate as a pneumatic position converter. An angular movement of 125 ±10%

gives a full range adjustment of regulated pressure, e.g. 3-15psig.

Torque load required to move lever is 13.75 Nmm (0.125 lb.in)


Volume Boosting Air Relay:

Remote control of regulated pressures possible with minimal air usage;

•Normal Direct relationship (1:1) between signal

and regulated pressures

•Bias Positive or negative bias between pilot

signal and regulated pressure can be set up of up to 2bar/30psig

Physical

•Operating Temperature -20C to +70C

•I.P. Rating IP65

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

Construction

Model Types

•Vibration The unit is unaffected by moderate vibration

•Mounting Position Operation in any attitude is possible; integral mounting nut supplied.

•Panel mounting or through mounting holes on the unit (lever, plunger and pilot)
