Actually it is called "Cla-val" and they make different valves including pressure relief valves which also have further sub-groups. For those interested, the web page is, you guessed it, www.cla-val.com

That is the name of a manufacturer. We don't call sprinklers a Tyco or a Viking, do we? What KIND of Cla-Valve? They make every type of hydraulic control valve imaginable ... Sorry to be so anal-retentive, but terminology is everything on this subject.

Combine the flow test at nowhere close to what you should be seeing, with steam coming from the diesel, makes me think you've got a whole lot of water being pumped in a circle and overheating. The cooling water for the diesel engine likely comes from the suction side of the pump and is pulling in that overheated water.
