AH-Series
4 Ton to 50 Ton Hydropneumatic Cylinder
The AH-Series Hydropneumatic Cylinder is an “all in one” self-contained air-over-oil cylinder package that produces hydraulic intensified force using factory supplied air. Excellent for assembly projects, machine integrators, or machine tool builders that don’t want to deal with costly, high voltage hydraulic power units, these cylinders come at a lower cost, are quieter during operation and require less maintenance than full hydraulics. Our AH-Series Hydropneumatic Cylinder also takes up less space and can be easily designed into your next assembly system projects, offering a range of output forces up to 50 tons.
This hydropneumatic intensifier is ideal when you want hydraulic intensified power without noisy motors, leaky hydraulic tanks or heat and energy issues that come with full hydraulic presses.

AH-Series Hydropneumatic Cylinder Animation
Hydropneumatic Cylinder Operation:
1 Actuating valve 1 pressurizes port 1, causing the float piston to move, transferring oil from the oil chamber onto the work piston at air pressure. The work rod extends at low pressure.
2 When the work is met, valve 2 is actuated, pressurizing port 2. This causes the booster piston and rod to extend, intensifying the pressure on the work piston, creating a high force.
3 – 3A Upon completion of the work, both valves are reversed, pressurizing ports 3 and 3A, retracting the cylinder to it’s start position
