Definition of "Offset Position" for Directional Control Valves

Definition of "Offset Position" for Directional Control Valves

(OP)
Hi, this is a basic question but cannot find a direct answer.

What is meant by the term "In Offset Position" for Directional Control Valves?

More specifically, the description is as such:

"Single Solenoid, 2 Position, spring offset.  P to B and A to T in offset position."

Does this mean that this is the function of the DCV when activated or when at rest?  What is the normal position of the spool?


My problem is that I possibly have the wrong solenoid configuration as I have the solenoid on the opposite side of what the schematic says.

I ordered a Parker D1VW020HNYGF56 as opposed to a D1VW020BNYGF56.  The difference is the "H" versus the "B" spool configuration.

Thanks in advance.

RE: Definition of "Offset Position" for Directional Control Valves

Spring offset and P to B and A to T in offset position means the valve connects port P(pressure) to port B and port A to port T(tank) when the solenoid is not energized.

So just to recap:

A DCV in the offset position is when the solenoid is NOT energized, correct?

RE: Definition of "Offset Position" for Directional Control Valves

Correct. Most refer to it as "The At Rest Condition."

It's in the Basic book.
