Third Function Preference

[J_J]

Since you posted just after me, it is apparent that you think something I posted is not correct.

If there is misinformation here, and it is mine, then get off your superior attitude and correct it.

I thought I was on your ignore list, but I see that you read my post anyway just so you can find fault.

However if you do see something, please correct it, as I am sure you never make mistakes.

If you have something to say, say it and don't whine about it.

Here is the one that I sell.

On my JD 2030 I used a rear SCV since I had one available. I would have required the 2 function mid valve to be replaced with a 3 function valve, too expensive of an option.
On my JD 6415 the mid mount loader valve is a "stacked valve" I found the 3rd function valve for the stack at a very good price and went that route. It is a solinoid controlled valve. I could have used a rear SCV since It has those too.

That's ok JJ I beleive you!...........Of course what do I know. :confused3:

Wow, such misinformation here...

Felt the need to leave that comment yet you don't elaborate or correct it? Don't bother posting that then.

One of these Surplus Center - 12 VDC 10 GPM OC DA SOLENOID VALVE

One of these Surplus Center - 1 STATION DO3 SUBPLATE OPEN CENTER

These valves are all PB.

They are? Where does the optional PB sleeve plug into? What is the part number for the PB sleeve?

The subplate may indeed be rated for high pressure on the outlet side, but to say that "These are all PB" is a false statement.



--------------------------------------------------------------------------------------------------------------------------------------------------------------------

PB refers to the ability to handle the high pressure.

What? The definition of Power Beyond has nothing to do with the "ability to handle the high pressure".



From this link: Hydraulic Terms

"Power Beyond - An adapting sleeve which opens a passage from one circuit to another. Often installed in a valve port which is normally plugged."





From this link: What is Power Beyond? : Explanation of the Power Beyond hydraulic system.

Situation or Problem

Need more explanation on what Power Beyond is used for.

Summary

The Power Beyond hydraulic system is used as a pressure/flow source for additional functions equipped with independent flow control valves. For example, planter vacuum motors, spray pumps, lift cylinders. Use Power-Beyond when:

Tractor SCV control is not needed.
Implement control valve requires external load sense signal to prevent pump operation at high pressure.
No other SCV outlet is available.

One major difference between a Selective Control Valve (SCV) and Power Beyond is an SCV has pressure/flow compensation whereas Power Beyond does not. An SCV section has an internal component referred to as a pressure compensator valve. The pressure compensator valve acts as a pressure regulator in the SCV section to maintain constant flow regardless of any other hydraulic function used.

For example, a hydraulic motor running on SCV #1 may require 10 gallons per minute of hydraulic flow at 1500 psi. If SCV #2 is engaged to run another hydraulic function that requires 6 gallons per minute at 2000 psi, the compensator in SCV #1 will balance this pressure change from hydraulic pump and maintain steady operation of the hydraulic function from SCV #1.

For more information on Power Beyond for remote hydraulic connections, refer to tractor Operator's Manual.

Done.

You know better, you just are not thinking.

http://www.surpluscenter.com/Drawing/DR9-5883-1.pdf

These sub plates are rated for 5000 psi, but maybe that is not high pressure.

Do you think those ports might be refered as a PB port. Yep, I think so.
