Servo Valve DECV: More precision and lower operating costs for hydraulic control systems
Designed for High Loads
The development of the DECV valve was focused on applications with high mechanical loads. The DECV's extraordinary parameters are also confirmed by its daily work environment outside laboratory conditions. For example, the servo valve has already proven itself in punching/nibbling machines under cyclical shocks of several hundred g (> 2,000 m/s²).
Cost Reductions through Simple Oil Filtering
The Voith DECV valve is affected very little by oil impurities and can be used with oil of the cleanliness class 19/17/14 as per ISO 4406. This oil quality level can be reached with a common bypass filter system. Comparable servo valves often require higher purity levels, which can necessitate the use of expensive pressure filters. The Voith DECV therefore reduces the system's operating costs.
Simple Integration and Remote Maintenance
The programmable control electronics of the DECV offers all common interfaces, which simplifies integration into existing systems. The HS4-SV2 controller used in the DECV valve contains, in addition to the power amplifier for control, a configurable PLC/CNC. Frequently occurring user cycles are already integrated and can be customized easily via field buses for specific requirements. Diagnostic data can be retrieved via Ethernet from anywhere in the world using the "PunchMaster" software tool belonging to the HS4 controller. This ensures the identification of faulty cycles and the quality assurance during production. An integrated sensor measures the pressure directly at the process connection and ensures extremely accurate and dynamic process monitoring and control. This avoids downtimes, which reduces the costs of repairs and service calls.
