Question by: Ray W on Aug 25, 2025, 5:35 PM

got a system that runs close to 5,000 psi, is this VD8A/U4S ok on the work ports?

Answer by: Customer Support on Aug 26, 2025, 6:32 PM

On ports P, A, and B the maximum operating pressure is rated at 5100 PSI, so it is intended to handle systems running up near 5,000 PSI on those ports.

Question by: Sherry P on Aug 13, 2025, 6:41 AM

what's the highest pressure this valve outlet can handle on the work ports?

Answer by: Customer Support on Aug 14, 2025, 12:36 PM

Ports P, A, and B are all rated to 5100 PSI maximum operating pressure. Port T on the outlet side has a much lower ceiling at 363 PSI back pressure, so that one needs to stay well within range. The specs were validated using mineral oil at 16 cSt viscosity, so keep that in mind when comparing to your system conditions.

What kind of fluid should I be running in this thing?

Answer by: Customer Support on Nov 7, 2025, 6:49 AM

Optimal fluid viscosity for the VD8A Series valve outlet is between 12 cSt and 75 cSt, but it can handle mineral oil with a viscosity of 16 cSt.
