Pneumatic Power Cylinder - Pneumatic Regulating

FEATURES :

Precision Linear Pneumatic Positioner is fitted with reversible cam which acts
as a position feed back. The Linear Positioner which is mounted on a subbase, converts an ON OFF linear cylinder to regulating. The power cylinder can be integrated with standard mountings and various accessories.The positioner is high quality, flapper nozzle type.

SPECIFICATIONS :

Accuracy ± 1%
Repeatability ± 0.5%
Hysteresis ± 0.2%
Dead band ± 0.1%
Input 3 – 15 psi

All specifications are related to full scale

PNEUMATIC CYLINDER :

Standard ISO 6431 (UPTO Ø160 mm)
Diameter Ø32 to Ø1100
Stroke 50 mm to 1800 mm
