Readers ask: What Is Power Beyond On A Tractor?

Configuring mobile hydraulic valves using power beyond

When driving a mobile hydraulic vehicle in North America’s industrial parks and off-road areas, drivers should make sure they are following instructions for installing an additional directional control valve, rather than just using the power beyond facility on existing directional control valves.

What is power beyond?

The power beyond facility, also known as high-pressure carry over (HPCO), is a feature on a mobile hydraulic directional control valve that allows the pressure gallery to be isolated from the tank gallery and carried over to another valve. The power beyond facility is configured differently depending on the valve type and manufacturer.

What is power beyond used for?

When Tractor SCV control is not required, the Power Beyond hydraulic system is used as a pressure/flow source for additional functions equipped with independent flow control valves, such as planter vacuum motors, spray pumps, and lift cylinders.

What is a power beyond block?

In a nutshell, Power Beyond (the first DCV) is a feature in the outlet section of a mobile directional control valve that allows the pressure bypass gallery to be isolated from the tank gallery, hence the name Power Beyond (the first DCV).

What is a power beyond Kit John Deere?

The power-beyond kit allows you to access pressurized hydraulic oil at the rear of the tractor to operate attachments like a backhoe and a log splitter that have an open center control valve.

What does Pb mean in hydraulics?

When the valve spool is centered, oil flows into the “P” pressure port and out the “PB” port, but there is no flow out the tank port.

What is the power beyond?

Power beyond, also known as high-pressure carry over (HPCO), is a feature on a mobile hydraulic directional control valve that allows the pressure gallery to be separated from the tank gallery and transferred to another valve, usually another directional control valve.

What is a tractor SCV?

Implements, which use hydraulic oil to perform a variety of functions such as raising and lowering parts as well as providing power to motors and other devices for mechanical movement, are the most common use of hydraulics off the tractor, with selective control valves (SCVs) controlling the volume of flow.

What does open center hydraulics mean?

The open central path of the control valve when the valve is in neutral refers to the hydraulic pump’s continuous flow type. When the valve is neutral, hydraulic fluid returns to the reservoir or the tractor housing, so open-center systems always have oil flow.

What does G mean in hydraulics?

v = flow rate (m/s) g = gravity acceleration (9.81 m/ssup>2/sup>)

What does C stand for in hydraulics?

CLOSED CENTER VALVE. When the valve is in its center or neutral operating position, pump output is not unloaded to the pump. CLOSED CIRCUIT. A piping arrangement in which pump output, after passing through other hydraulic components, returns directly to the pump inlet.

What does A and B stand for in hydraulics?

The pressure inlet is P, the utilization ports are A and B, and the return ports are TA and TB.
