Loader pilot valve circuit

966G Wheel Loader and 972G Wheel Loader Steering …

The rotation actuates the steering pilot valve. When the steering pilot valve is in the OPEN position, pilot oil is allowed to flow. The pilot oil flows from the steering pilot valve and through the steering quad check valve. The pilot oil then flows through the neutralizer.

Wheel Loaders

Load-holding bridge circuits provide the advantage of independent meter-in and meter-out timing with integral load sensing and pilot signaling, with minimal leakage. Circuit complexity, size and cost are minimized by using multi-function cartridge valves. Use a.

Check Valves, Flow Control and Priority Flow Control Valves

Deselecting a priority circuit using a 4 port ventable priority flow control. 2-Way Normally Closed Valve This drawing is not a real circuit and is intended for description only. In this example, a 2-way valve is used to deselect the priority circuit when it is not need.

Hydraulic Load Holding: P.O Checks vs. Counterbalance …

Typical pilot-operated check valve applications include: stopping a cylinder in place when the directional valve is centered, holding a clamp in position, or maintaining a tool position. If a load must be controlled while in motion, a counterbalance valve should be used.

The circuit in Figure 14-20 shows an external pilot-operated pressure control valve teed into the cap-end line to provide a path for excess fluid to flow directly to tank. Giving the extra oil a second path reduces rod-end pressure and wasted energy.
