VD12A Series SALAMI VD12A/U4S

On the pressure port marked "P", the maximum operating pressure is 4000 PSI. Ports "A" and "B" are rated higher at 4500 PSI, so the port you load matters.

At 130°F ambient you're well within the rated range. The VD12A series is tested for ambient temperatures up to 140°F, so that kind of operating environment shouldn't cause any concern. Fluid temperature is a separate consideration though. As long as your hydraulic fluid stays between -4°F and 185°F with standard NBR seals, you're in good shape on that front too.

Optimal fluid viscosity for the VD12A Series valve is between 12 cSt and 75 cSt, though it can handle 10 cSt to 460 cSt. All the data was gathered using mineral oil with a viscosity of 16 cSt.

Pressure ratings are split by port on this valve outlet. The maximum operating pressure is 4000 PSI on the P port, and 4500 PSI on the A and B ports.

This valve outlet is designed for use with hydraulic fluids within a viscosity range of 10 cSt to 460 cSt, with optimal performance between 12 cSt and 75 cSt. The technical data was gathered using mineral oil with a viscosity of 16 cSt, so that’s a good baseline.
