through a CLOSED CENTER <strong>Valve</strong><br />
Hydraulic Intensifier:<br />
The Hydraulic Intensifier and associated components<br />
(mounted on a Delron plate) are mounted on the<br />
ROV. The hydraulic intensifier is an Iverson with a 4:1<br />
ratio (ie at 2,500 psi inlet pressure it produces 10,000<br />
psi outlet pressure).<br />
