what's the max pressure this spool can handle runnin a parallel circuit setup?
Answer by: Customer Support on Jun 30, 2025, 7:38 AM
Running parallel circuit, the SD11 series tops out at 4600 PSI. Drop it into a series circuit and that ceiling comes down to 3600 PSI. Worth keeping that distinction in mind when you're sizing things up for your system.
