A New Chapter of Intelligent Hydraulics: The New Generation of High-performance Travel Valves Enhances System Efficiency and Reliability

With the continuous growth of the demand for Industry 4.0 and automation, the core control component of hydraulic systems - the travel valve - is experiencing a wave of innovation. Danfoss Power Solutions, a global leader in hydraulic technology, recently released its new generation of high-performance travel valve series. This product is designed to meet the demands of the next generation of construction machinery and industrial applications through outstanding precision, reliability and unprecedented diagnostic capabilities.

Beyond traditional functions: From sequential control to intelligent diagnosis

As a pressure control valve, the traditional function of a travel valve is to ensure that multiple actuators in a hydraulic system act in the preset sequence. For instance, in an injection molding machine, the mold closing action must be completed first before the injection action can commence to prevent equipment damage. Although traditional valves can achieve this basic function, they have limitations in response speed, pressure setting stability, and integration with modern electrical control systems.

Danfoss 'new travel valve addresses these challenges through the following innovations:

Ultra-fast response: The optimized pilot-stage design has reduced the response time by approximately 30%, ensuring precise and timely action switching and significantly enhancing the working cycle of the equipment.

Outstanding stability: By adopting a new type of hardened valve core and precise manufacturing process, internal leakage and pressure fluctuations are effectively reduced. Even in harsh environments with high oil contamination, it can maintain long-term stable performance.

Integrated electronic sensing (optional) : This is the core highlight of this update. The valve can be optionally equipped with an integrated pressure sensor and an IO-Link communication interface, which can provide real-time feedback on the system pressure status to the host controller. This enables operators to remotely monitor the working status of the valves, achieve predictive maintenance, and reduce unexpected shutdowns.

Address a wide range of application challenges

In fields such as automated warehousing and logistics, high-performance metal forming machine tools, and advanced agricultural machinery, the requirements for the accuracy and reliability of action sequences are extremely strict. Andreas Weber, product manager of Danfoss Hydraulics, said, "Our new series of travel valves not only offer robust and durable mechanical performance, but their 'intelligent' options also open the door to digital hydraulic systems for Oems."

The core value brought to system designers

For equipment manufacturers and system designers, the advantages of this new product are obvious:

Enhance efficiency: A faster response speed directly translates into a higher device cycle speed.

Enhanced reliability: A more robust design and intelligent diagnostic functions reduce the risk of failure and maintenance costs.

Simplify system integration: Plug-and-play intelligent valves reduce the reliance on external sensors, simplifying wiring and management.

Looking forward to the future

The launch of the new generation of travel valves marks that hydraulic components are evolving from single-function parts to intelligent and integrated system solutions. With the continuous improvement of requirements for energy efficiency and production efficiency, intelligent hydraulic components with perception and communication capabilities will become the standard configuration of future industrial equipment.
