Parker, which was founded in 1917 in Cleveland, Ohio, initially manufactured pneumatic brake systems for trucks, trains, buses, and industrial machinery, as well as leak-free fittings for aviation pioneers. Today, the company is the largest supplier of hydraulic valves for industrial, refrigeration, and aerospace applications in the world.

What is a Proportional Valve?

Proportional valves control the flow and pressure of liquid or oil in hydraulic systems. They consist of:

• Directional Control Valves: The most common use of a proportional valve is to control the direction and speed of a hydraulic cylinder or motor. They can direct the flow of fluid in a specific direction. They can change the direction of fluid flow. They can also pause and restart the movement of fluids.
• Pressure Control Valves: Pressure control valves regulate the pressure of water passing through the system, keeping the pressure below a set limit and releasing excess pressure to control leakage and bursting of pipes.
• Flow Control Valves: Flow control valves control and adjust the flow of fluid or gas through the system and can optimize the performance of the system. Flow control valves monitor and regulate pressure fluctuations in the system.

Preventive Maintenance for Hydraulic Valves

A brand-new valve should operate at peak performance. It’s important to set up and stick to a plan of regular maintenance to ensure that it will function properly and run longer.

One downside of waiting until a valve fails is that is causes a major inconvenience. Production will stop until it can be repaired or replaced, and lost production has to be made up, which often happens on overtime. This is clearly the most expensive way to maintain a hydraulic valve.

If a valve has to be removed from service for repair, a technician will use diagnostic tools to discover any issues without having to shut down the system. These tools can help identify exactly what is wrong and can get it back into action quickly.

Another effective way to reduce downtime and maintenance costs is predictive maintenance. This allows a technician to test valves to establish performance baselines that will guard against future problems. When it’s time for annual maintenance, valves that are tested again and still performing within range of the baseline may not require service.

Of course, sometimes valve repair is necessary. The most common reasons are internal leakage, external leakage, sticking in place, and complete failure. This usually means that the value was not designed for the conditions in which you are using it.

Always pair the right hydraulic valve with the right application, stick to a regular maintenance plan, and you can get decades of use out of your equipment.
