Using an intensifier, mounted outside the jack, allows a higher pressure to be obtained and thus a smaller cylinder used for the same lift force. Intensifiers are also used as part of machines such as hydraulic presses, where a higher pressure is required and a suitable supply is already available.

How do pressure intensifiers work?

Hydraulic pressure intensifiers, sometimes referred to as hydraulic pressure boosters, generate a higher pressure from a low-pressure hydraulic power source. They always work powered by a pump, which is operating at a set pressure and from this the intensifier simply generates a higher output pressure.

What is the purpose of intensifier circuit?

This circuit provides rapid low-force advance and retract strokes, with a short high-force work stroke when the cylinder meets resistance. Solenoid-operated directional valve B extends the air part of the tandem cylinder. Sequence valve D operates intensifier C.
