Proportional valve: advantages and challenges

A dynamic technology, automation and compactness: a proportional valve presents these and many other advantages. However, there are some challenges that need to be addressed in order to reach top-tier performances.

On this page, we will deepen our knowledge of: 

• The advantages of a proportional valve 
• The challenges a proportional valve needs to deal with 

The advantages of a proportional valve 

A proportional valve features a vast array of advantages that are functional on an operational level. Here you can find a list of the most common benefits. 

Precise regulation 

Proportional valves are designed to monitor the systems’ flow and pressure rate. They can easily adapt to many different contexts as they can be fine-tuned at any time in order to align with specific needs. Unlike solenoid valves, proportional valves can be adjusted as they allow more control over the system’s regulation processes. 

Energy optimization

One of the main advantages of a proportional valve is a significant increase in energy efficiency. As a matter of fact, these systems need less manual operations to adjust flow and pressure rates, resulting not just in an economic benefit, but also in a sustainable optimizationof energy consumption.

Versatility

Proportional valves can adapt to many different contexts and applications - from industrial automation to Food&Beverage and delicate medical systems. They can also manage a variety of fluids and pressure rates, ensuring excellent performances in every field they may be applied to. 

Enhanced safety

Accuracy and constant monitoring mean improved safety. In fact, these systems prevent sudden fluctuations that can lead to operational shifts and malfunctions. 

IT Integration 

Nowadays, proportional valves are more dynamic and smart. The integration of IT electronics enables operators to monitor performance in real-time, easy access to reports, and feedback mechanisms, enhancing their functionality and reliability.

The challenges a proportional valve needs to deal with 

While the proportional valve advantages are significant, it is important to be well aware of certain challenges that may arise. 

• A complex design could result in difficult installation and maintenance. For this reason, proportional valves should be handled by skilled experts or may require specific training and equipment. 

• When it comes to proportional valves, economic considerations are instrumental to understanding if the initial investment is worth it. In fact, these systems can cost more than solenoid valves, although they can improve energy consumption and reduce maintenance operations. 

• Proportional valves can be extremely sensitive to external factors such as temperature variations and electrical interference due to the presence of sensors installed on them. These elements could affect their overall performance and precision.
