CEB Press v16.09 - Scott II brick press - 20F temperature in workshop for testing in the snow - pressure on Surpluscenter DO3 valve was 700 psi at flowthrough on valve after CEB inlet. That is excessive. It could be the cold. It was going through 6 quick couplers - Power Cube, PC extension, CEB valve inlet, outlet, PC extension, PC. But it was on low throttle of 14 GPM. Verify that pressure is reduced significantly when it short circuits just through Power Cube. In actuality, this is going through 4 quick couplers (restriction points) - as it's after PC and extension.
Likely conclusion - cold temperature.
Waiting for warmup to 90F+ should resolve this
Use an IR termometer or just feel the hoses.
Also, check the short circuit condition and second P gauge to verify correct P reading on valve.
Expecting 300 PSI or less pressure upon freeflow. Can measure after the valve to get data points for optimizing system.
15% power loss is acceptable. For 2000PSI, that is 300 PSI.
