Details:

The Fairchild 1000 Precision Pressure Regulator is designed for use in systems requiring both precision control and high forward flow and exhaust capacity. The sensitive valve motor of this high quality unit makes it virtually immune to supply pressure variations.

Features

  • Stable operation that eliminates hunting and buzzing.
  • Flow compensation provided by venturi action of the aspirator tube.
  • Indirect operation provided by the action of a separate pilot valve and valve motor to eliminate unbalanced closing forces in inner valve assembly.
  • Large correcting effect due to the sensitive pilot valve action that maintains constant pressure drop across the supply valve to assure immunity to supply pressure variations.
  • No-Bleed design minimizes consumption of air or inert gas.
  • Compact in size where space is limited.

Operating Principles

The combination of high flow capacity and good sensitivity make the versatile control applications, including loading of control valve and calendar roll actuators, operation of clutch and braking devices, and winding operations.

FIPA presents: Oval vacuum cups

Introducing the newly developed oval vacuum cups series.

The vacuum cups are characterised by a very long cycle life, which has also been successfully demonstrated against vacuum cups of competitors in practical operation. The long service life is enabled by means of a new high wear- and oil-resistant NBR material and a special vacuum suction cup construction which minimises the load on the vacuum cup during handling.

FIPA presents: New ID grippers for parts with different diameters

Flexible and service friendly

The pneumatically operated, single-acting ID grippers from FIPA GmbH have already established themselves as the alternative for workpieces with holes or cut-outs or for when vacuum cups or grippers aren’t just right for handling goods. FIPA has completely overhauled its portfolio and now offers users maximum flexibility with minimal set-up time.

The small ID grippers are now equipped with food-safe gripper heads made of polyamide (PA) and are suitable for light and small parts with openings measuring 3 to 10 millimeters in size. If necessary, the gripper heads can be easily exchanged in a non-destructive manner.
