Ramp Rate control By manual adjustment of hydraulic drive pump air drive pressure

Decompression Manual control

Pressure  measurement Pressure indicator on hydraulic drive pressure circuit scaled by intensification ratio (20:1) to indicate the high pressure in the pressure vessel.

Note a high pressure transducer and display in the high pressure circuit is optionally available, if scaled pressure is not acceptable.

Pressure control Manual. System includes an adjustable relieve valve on the drive hydraulics to enable pressure to be limited. To within safe operating pressure range.
