Electrohydraulic servo valves are widely used in hydraulic systems to control the position, speed, and force of hydraulic actuators. The technology hasn’t progressed much since the 1950s and there are key limitations that still exist. In this article, we will examine the benefits of switching from mechanical to electrical feedback. What
Electrohydraulic servo valves are electrically controlled valves that provide hydraulic actuation. Their basic working principle is that they take a digital or analogue electrical signal, and transform it into a hydraulic actuation output. Servo valves are critical components in modern hydraulic systems, providing precise control over hydraulic motion in aerospace,
Closed-loop hydraulic displacement control systems like EHAs (Electro Hydrostatic Actuators) can improve energy efficiency when compared to traditional metering valve-controlled systems, for example via the elimination of throttling losses. Domin’s advanced additive manufacturing techniques enable miniaturisation while also allowing for the design of optimised fluid flow channels to improve flow efficiencies.
Our approach to innovation stems from a desire to challenge the status quo. By pushing the boundaries of conventional systems and embracing cutting-edge technologies, we have created something new. This relentless pursuit of efficiency and performance optimisation in hydraulics will create cutting-edge solutions that surpass the limitations of existing hydraulic
Traditional centralised hydraulic systems are heavy and inefficient. They are built with a number of different components, meaning that energy is wasted and efficiencies are throttled. At Domin, we have revolutionised the way hydraulic systems are built, making them much more efficient. In this article, we are going to explore
Hydraulics, a key aspect of fluid power, are widely used in the automotive industry for a range of systems that can include active suspension, brakes, and power steering. Hydraulic systems provide a lightweight, safe, and high power-to-weight ratio and with the integration of digital systems, hydraulics are set to find
Hydraulic servo valves are commonplace in the aerospace, automotive, and industrial manufacturing industries, among others. Yet, for the most part, they still rely on decades-old, inefficient technology. This article will take a look at how Domin is challenging this, and how to choose the best hydraulic servo valves for industrial
How We Developed In-house Powder Extraction Capability for our Additive Manufacturing Processes What is Powder Extraction? The finished product that comes out of a 3D printer often has leftover powder sitting within its printed parts. This residue needs to be carefully removed from the manifolds before they can be used
Background Delta Motion is a manufacturer of industrial automation products specialising in high performance hydraulic motion control. They offer extensive hands-on training programs and support for their customers. Importantly for Domin, Delta Motion tests a wide range of servo and proportional valves, including those from Domin’s competitors. Their test setup
Hydraulic servo valves are used for a wide range of precision control applications found in the automotive, aerospace, and general manufacturing industries. Apart from the actual servo mechanism, the spool component in these valves is key to the effective operation of the valve. What is a Spool? A “spool” is
Hydraulic systems play a crucial role in numerous industrial applications, from injection moulding and wood processing, to die casting and metal forming. These systems rely on various components to ensure effective and efficient operation. One component that is key to maintaining precision and performance are the hydraulic valves that control
Hydraulic systems are widely used across a range of industries such as aerospace, robotics, and automotive and are used to leverage the power of fluid mechanics to transmit force and control movement effectively. Although hydraulic systems can be complex, they consist of five fundamental components: Hydraulic Fluid At the heart
