Latest innovations in servo valves
1st Quarter 2016
Hydraulic systems & components
The new Direct Electronic Copy Valve (DECV) servo valve from Voith Turbo is the latest development of this product, which has already proven itself in countless hydraulic control systems. It combines excellent operating characteristics and robustness with innovative valve and associated electronic control. Impulse response and accuracy means that the DECV is responsive to demanding drive tasks. A step response of only seven milliseconds places it in the class of highly dynamic valves. The direct actuation allows a hysteresis of under 1%.
The DECV is aimed at applications with high mechanical loads and has already proven itself in punching/nibbling machines that clock up a G-force in the hundreds (>2 000 m/s²). It is unaffected by oil impurities and can be used with oil of cleanliness class 19/17/14 as per ISO 4406. This oil quality level can be achieved by means of a common bypass filter system. Comparable servo valves often require higher purity levels requiring expensive pressure filters.
The programmable control electronics offers all common interfaces, which simplifies integration into existing systems. The HS4-SV2 controller used contains a configurable PLC/CNC in addition to the control amplifier. Diagnostic data can be retrieved via Ethernet from anywhere in the world using the PunchMaster software tool accompanying the HS4 controller. This ensures the identification of faulty cycles and quality assurance during production. An integrated sensor measures the pressure directly at the process connection, ensuring extremely accurate and dynamic process monitoring and control. This avoids downtime, which in turn limits the need for costly repairs and service calls.
Voith Turbo, a group division of Voith GmbH, is a specialist in intelligent drive solutions and systems. Customers from highly diverse industries such as oil and gas, energy, mining and metal processing, mechanical engineering, ship technology, rail and commercial vehicles rely on advanced technologies from Voith Turbo. Voith sets standards in the markets of energy, oil and gas, paper, raw materials, transport and automotive. Founded in 1867, Voith today has more than 39 000 employees, sales of €5.3 billion and locations in more than 50 countries, making it one of the largest family-owned companies in Europe.
