For further information

High-precision manual pressureregulator

Highly sensitive and accurate

Perfect for dead-end applications

Excellent long term stability

Handwheel, lever, plunger orpilot operated

Note: The R27 is a high precision manualpressure regulator which regulates pressure byuse of a control chamber, instead of a spring,so increasing its sensitivity to any variationsand eliminating any spring hysteresis.

The R27 is perfect for dead-end applications.

TECHNICAL DATAMedium:

Dry, oil free air filtered to 25 μm

Maximum inlet pressure:

10 bar

Ambient temperature:

-20°C ... +70°CConsult our Technical Service for use below +2°C

Gauge ports:

G1/4

Flow capacity:

Up to 300slpm

Sensitivity:

Better than 0,3 mbar

Hysteresis & repeatability:

Less than 0,05% setting at midrange

MATERIALSBody: passivated zinc diecasting

Internal springs: mild steel

Elastomers: reinforced nylon
