There are a couple of methods used in the mobile hydraulic market to control multiple actuators from a common pump supply. The most simple is the monoblock valve, which typically has a cast iron housing and a machined spool operated by a spring centered lever, although solenoid operation is available for nearly every brand of valves. The monoblock valve is available up to at least eight spools, each able to operate a function of their own. The most basic of these valves have no auxiliary valves except a relief common to the pressure ports of every spool. Although rare, monoblock valves can be optioned with components in the inlet or work ports of the valve, such as pressure compensators or work-port relief or counterbalance valves. If you are a mobile OEM using hundreds or thousands of the same configurations, a monoblock valve is the simplest direction to take.
Does any one have any suggestions for him?
Run the new cable, with sheathing, at least two inches up inside the box, and double over the excess wires to help hold the cable in place. Strip 5/8-in. of insulation off the ends and connect the wires from the new cable to the existing bundles - white to white, black to black, ground to ground. Late ones where easy to hook up powerbeyond. Late is on bottom just have to remove pipe and cap one end and hook hose to other Quote; Link to post Share on other sites. jimb2 76 Posted January IH Power Beyond Valve Theme. Default. RPM_ips4. RPM_ (Default). Power beyond - also called high-pressure carry over (HPCO), is a facility on a mobile hydraulic directional control valve which enables the pressure gallery to be isolated from the tank gallery and be carried over to an additional valve - usually another directional control valve. The valve being installed must be sized to handle the rated flow.
Does he have separate hydraulic control valves for the loader or is he trying to use the rear remotes? There is another method of connecting a loader to a that does not use the rear remotes but requires hydraulic control valves for the loader.
Let me know and I will post a diagram as how a IH loader was attached to my brothers and then we moved it to his CIH Early or late 85 series? Late ones where easy to hook up powerbeyond. Late is on bottom just have to remove pipe and cap one end and hook hose to other.
His loader is installed like the bottom third of the diagram, lift seat and deck plate, remove pipe item 39 that is sort of "L" shaped pipe that goes from the top of the remote control valve back to draft control unit at rear near fuel tank, cap off the connection into the draft control unit, install high pressure hydraulic hose item 30 on elbow where pipe item 39 was connected on top of remote control valve and connect other end of hose to the IN Port of the loader hydraulic control valve then the OUT port is to hydraulic hose item 30 to the hydraulic drain plug under the right axle with parts items 27, 28, Andrewn just posted a photo of loader connections, 2 is the one I am describing.

Jan 05, The best way to hook it up would be to a power beyond kit but I have heard of people hooking it to the SCVs and using a bungee strap to hold the valve open. I can't say whether or not this would be harmful but for occasional use I would think it would be fine. If you use it a lot you should probably get the power beyond kit.

Jan 16, The advantage to power beyond is in allowing you to hook up optional sub-circuits to a standard configuration, like adding a log-lift function to a log splitter. The downsides are the extra plumbing, which lead to leaks, and also an annoying effect related to the first valve in the chain tending to steal flow for its operations.
The arrangement of the power beyond facility varies with valve type and manufacturer. However the most common arrangement is a facility to install a threaded plug or sleeve that blocks the drilling between the pressure and tank galleries inside the valve. The power beyond port is then used to supply pump flow to the additional directional control valve.
Dec 05, Power Beyond is a feature that a hydraulic control valve may have - or may not have. It is only a valve feature. It stops there. I think the confusion that exists around Power Beyond is that other stuff is often sold along with it - and the impression is left that the added stuff is part of Power Beyond. Power beyond - also called high-pressure carry over (HPCO), is a facility on a mobile hydraulic directional control valve that enables the pressure gallery to be isolated from the tank gallery and be carried over to an additional valve - usually another directional control valve. The valve being fitted must be sized to handle the rated flow.

Most mobile directional control valves can be made closed center by plugging the drilling between the pressure and tank galleries and leaving the power beyond port plugged Figure 3. This means that if the existing valve is closed center, supplying pump flow to the additional valve only requires the connection of its pressure line to the existing valve's power beyond port Figure 4.
