Hydraulic Feed Controls
VC25125F

For precision adjustment of feed rates

Adjustable
Compression force max. 787 lbs
Stroke 4.92 inch

Precise adjustment for any type of application: Hydraulic feed controls of the product family VC are ideally suited for the precise tuning of constant feed rates. The thread of the outer body of this closed hydraulic element allows simple assembly. Smooth outer bodies can also be supplied.

As the hydraulic oil is forced out through the throttle opening, a constant feed rate is achieved on the stroke. In the models up to 2.17"" (55 mm) stroke, the tried and tested rolling diaphragm, known from ACE shock absorbers, serves as a dynamic seal, as volume compensation of the piston rod and as a reset element.
