What Is The Importance Of Proportional Valves In A Hydraulic System?

Posted by Neilson Hydraulics & Engineering Ltd on August 16th, 2023

PVG valves are considered ideal in a variety of industries owing to their distinct features. The PVG 32 valve is known to be a hydraulic sensing valve. The design of this valve provides maximum flexibility, which makes it convenient to use in various hydraulic systems. Some varieties, like Danfoss PVG valves, provide a varied range from simple-load models to advanced models that are electrically controlled. The simple-load sensing options provide for smoother machine control as compared to other solutions. The design and technology used in such valves also come at a lower cost as compared to other valves. Here are some of the reasons why proportional valves are important in a hydraulic system.

Owing to their load-sensing technology

Most of the valves used in heavy machinery like hydraulic systems are prone to be subjected to heavy loads on a regular basis. Thus, an efficient Bosch Rexroth distributor deals with products that are capable of interfacing with other valve varieties and ensures that the entire machinery is able to be controlled by a single-valve mechanism. Some of these valves also have actuator technology. When this technology is combined with a low-pressure-drop design, it helps to improve the efficiency and overall performance of the machinery. This, in turn, enables the enhancement of productivity and also reduces the energy consumption of the machinery. A proportional valve group has the capability of functioning with load-independent flow control and can easily integrate with other proportional valves of higher groups. The load-sensing technology also allows these valves to reduce the energy loss at the target pressure. Apart from this, these valves also have an oil flow function that is independent of the load pressure. Choosing the right valve for your hydraulic system can also help gain the reliable characteristics of the entire flow range.

Owing to their precise matching performance

Proportional valves are popular for their precise matching of the performance with the flow requirements of the machinery. This makes them one of the most efficient valve options available in the market. A Bosch Rexroth distributor understands the importance of proportional valves in a hydraulic system. Thus, they ensure to include varieties like proportional valve groups that have distinct features. Such valves might also include a built-in pressure relief valve. The pressure gauge connection in these valves adds to their efficiency. These valves are low-weight and have a compact design that makes them easy to install.

Owing to their reduced fuel requirements

The modular designs of some of the choicest of valves, like Danfoss PVG valves, include full-flow dump characteristics. The integrated module also includes a pressure compensator along with a pressure gauge connection. These valves are compatible with various versions, including open-centre versions and closed-centre versions. Such valves also possess pilot gauge connections along with pressure gauge connections. The return flow characteristics of these valves enable minimal pressure loss. Their compact design and low weight ensure compatibility across various hydraulic systems.
