Excavator Control Valve – The Complete FAQ Guide

Have you ever wondered how your excavator’s hydraulic system works? Well, the hydraulic system in your excavator has different components that work systematically. One of these components is the control valve which plays a pivotal role in the hydraulic system.

Over time, your excavator control valve will start leaking, or in a worse case, it may fail. You’ll need to know when the control valve is not okay, and make a correct judgment of either rebuilding or replacing it. That’s what this guide is all about. You are going to learn the following from this guide:

• What an excavator control valve is, different types of control valves, how it functions, and why it is important
• How to install a new high-quality aftermarket excavator control valve. The guide will also teach you how to properly maintain, repair, and/or replace your excavator control valve.
• Where to get the best excavator control valve that will serve you for long with minimal downtimes meant for repairs.

Keep reading this guide to find out more.

1. What Is An Excavator Control Valve?

As you’ve read earlier in this guide’s introduction, your excavator control valve is a vital hydraulic component. It plays a pivotal role in controlling the excavator’s hydraulic oil flow in your excavator.

Figure 1 – Excavator Control Valve

Your excavator relies primarily on hydraulic power to function well. The control valve decides which component gets the most amount of hydraulic fluid depending on the intensity of work at hand.

2. What Do Control Valves Do in Excavators?

Control valves in excavators are used to control hydraulic flow in your excavator. Its primary task is to regulate both the direction and flow of hydraulic fluids in your excavator.

3. How Do Control Valves in Excavators Work?

The excavator’s control valve controls the flow and direction of hydraulic fluids using its general structure. It has poppets, ports as well as different pressure settings. Your excavator engine pumps hydraulic fluid under high pressure to the hydraulic system in general. The control valve receives hydraulic fluid under high pressure from the excavator’s main hydraulic pump.

The control valve is responsible for directing this hydraulic fluid to different components of the excavator that require hydraulic pressure.

Figure 2 – Excavator Control Valve Working Principle

Now, you can control the control valve by using an operating lever. You can find a control valve with a single-acting or double-acting lever. They actuate the valve’s position(s) in order with the direction of flow.

Check this out: Your excavator control valve can have these three types of levers:

• Manually Operated Control Valve
• Single Acting Hydraulic Operated Control Valve
• Mechanical Operated Control Valve

Your excavator control valve has a sleek design that maximizes the hydraulic system’s efficiency as it has self-lubricating bushings. These bushings can comfortably cut off or even fine-tune hydraulic fluid flow easily.

4. Where Are Excavator Control Valves Found in Excavators?

Control valves are found in the excavator’s hydraulic system in general. Remember, the control valve controls the flow and amount of hydraulic fluid leaving the main hydraulic pump to different parts of the excavator that require hydraulic pressure to run. You can pinpoint the exact location of your excavator control valve by using your excavator’s operational manual.

5. What Are the Components of An Excavator Control Valve?

Your excavator’s main control valve has the following components that work systematically:

• Adjusting screw
• Spring
• Cylinder
• Piston
• O-ring (piston)
• Upper Packing
• Bonnet
• Spacer
• Bonnet flange
• Seat ring
• Seat retainer
• Actuator stem O-ring
• Actuator stem bushing
• Stem Bellows
• Stroke plate
• Lower packing
• Plug
• End Flange

6. How Can I Select the Ideal Excavator Control Valve for My Excavator?

All excavator parts have unique part numbers, regardless of your excavator’s make or model. You can select the ideal aftermarket excavator control valve using its part number.

Figure 4 – Excavator Control Valve Selection Process

It is important to select the ideal excavator control valve for your excavator as it will undoubtedly affect the excavator’s performance. You can also contact a reliable excavator part manufacturing company to help you out with the selection process.

7. How Can I Tell If My Excavator Control Valve is Damaged?

You can tell if your excavator control valve is damaged by checking your excavator’s performance in general as well as visually inspecting it. Here’s how to tell if your excavator is operating on a damaged control valve:

• The excavator has a slow engine response when fast traveling
• The excavator emits a lot of black smoke and even frequently coks
• Unusual vibrations, as well as loss of power as the system, cannot reach the optimum pressure
• Abnormal amounts of hydraulic fluid leakages

The above four symptoms are the most common signs of a damaged excavator control valve. However, if you notice any other unusual signs, please contact your favorite excavator mechanic for proper diagnosis, repair, and/or replacement.

8. Why Is My Excavator Control Valve Leaky?

Excavator control valves can leak due to different reasons. There are two different types of excavator control valve leakage:

• Fugitive emission – the valve leaks hydraulic fluid outside the hydraulic system to the environment, posing health and environmental hazards.
• Internal leakage – this type of leakage is dangerous to the hydraulic system as hydraulic fluid leaks internally.

Figure 5 – Leaking Excavator Control Valve

The most common reasons for control valve leakages are:

• The control valve’s internal components are significantly worn out.
• The control valve’s actuator is not well set up.
• Improper maintenance
• Using low-quality materials, e.g. seals during maintenance

Your excavator control valve should not excessively leak hydraulic fluid. If it does, consider contacting your mechanic for repairs. You can further reach out to a professional aftermarket manufacturing company to find a perfect replacement for your faulty control valve.

9. How Are Control Valves for Excavators Repaired?

Control valves for excavators are repaired by rebuilding them. It is a complex process that requires great mental focus as well as precision. Leading experts recommend using high-quality internal parts during the rebuilding process.

Now, different control valves have varying repairing techniques. It would be best if you’d consult an expert to help you out. Remember, the control valve is a vital component in your excavator that must be handled with care. Improper rebuilding could damage other hydraulic system components.

10. How Should I Replace My Excavator Control Valve?

All excavator parts replacements must be done by a certified expert to prevent damage. They must also be done when the excavator is set on safe mode to prevent any injuries. Now, replacing your excavator control valve requires you to remove the old one and install a new one.

Figure 7 – Excavator Control Valve Replacement

You can complete that process by strictly adhering to the recommended procedures outlined in your excavator operational and service manuals. Remember, different excavator makes and models have different control valves – the manuals will issue instructions that are specific to your excavator make and model.
