VOSS Servo Actuated Control Valves are high-precision fluid control core devices designed for industrial and building automation applications. By integrating advanced servo drive technology with precision valve body engineering, they deliver accurate regulation of flow, pressure, and temperature parameters, and are widely used in HVAC, industrial processes, water treatment, and energy management systems.
Core Product Portfolio
Valve Series V-A
Full Range of Sizes: Available in two size ranges: DN15-DN25 (ideal for small-to-medium flow scenarios such as commercial buildings and laboratories) and DN32-DN50 (for large-flow requirements like medium-scale industrial production lines and large HVAC systems). Compatible with water, glycol, and other common media.
Premium Construction & Materials: Valve bodies are constructed from cast steel or stainless steel, with a streamlined internal design to minimize flow resistance and noise. Sealing components use temperature and wear-resistant EPDM or PTFE, ensuring stable operation across a wide temperature range of -10℃ to 120℃ for complex working conditions.
Actuator Options
High-Precision Servo Drive: Equipped with high-precision permanent magnet synchronous servo motors, offering positioning accuracy of ±0.5% and response time < 2 seconds. Supports 4-20mA, 0-10V, Modbus, and other standard communication protocols, enabling seamless integration with PLC, DDC, and other mainstream control systems.
Safety & Redundancy Design: Built-in overload protection, anti-seize mechanism, and power-off reset function. Optional IP54/IP65 protection ratings for reliable operation in harsh environments with moisture and dust. Some models feature manual emergency operation to enhance system reliability.
Multi-Scenario Application
HVAC Systems: Precisely controls chilled/hot water flow to dynamically match indoor thermal loads. When integrated with building automation systems, it can achieve15%-25% energy savings, making it ideal for commercial complexes, hospitals, and data centers.
Industrial Processes: Stabilizes flow and pressure in media transfer for chemical, food, and beverage industries, ensuring process consistency, reducing material waste, and minimizing equipment fluctuations.
Water Treatment & Municipal Applications: Accurately adjusts pipeline flow in water supply and wastewater treatment systems, enabling closed-loop control of water quality and pressure when paired with sensors to improve operational efficiency.
Core Value Propositions
Energy Efficiency: The combination of servo drive technology and low-flow-resistance valve design reduces pipeline energy consumption by 8%-12% compared to conventional control valves, delivering significant long-term cost savings.
Smart Connectivity: Supports IIoT integration, enabling remote monitoring, fault alerts, and data traceability via cloud platforms to help customers build digital management systems.
Safety & Reliability: The entire product range is certified to CE, ISO, and other international standards. Key components undergo over 100,000 cycle life tests, with a mean time between failures (MTBF) exceeding 5 years, reducing maintenance frequency and downtime risks.
Full-Lifecycle Service Support
Professional Selection: Provides free working condition analysis and customized selection solutions, matching the optimal valve and actuator combination based on medium characteristics, pressure ratings, and control requirements.
Installation & Commissioning: Offers detailed installation manuals and video guides, with on-site technical support available to ensure rapid system deployment.
After-Sales Guarantee: 7×24-hour nationwide response, 18-month warranty on core components, and fast spare parts replacement and on-site repair services.
