Brand New Pneumatic Control Valve Fisher DVC6200 DVC6205 DVC6215 Digital Valve Controller Valve Positioners Price
Split Design: Breaking Through Spatial and Environmental Limitations The Fisher FIELDVUE DVC6205/DVC6215 split-type valve positioner is specially designed for complex working conditions:
Remote Mounting Flexibility: The DVC6205 control unit and DVC6215 feedback unit can be installed separately, with a maximum spacing of 10 meters, adapting to special scenarios such as high-temperature pipelines and narrow spaces.
Extreme Temperature Resistance: The control unit withstands -40°C to 85°C, while the feedback unit operates at -52°C to 125°C. With special sealing materials (e.g., Kalrez), the temperature range can be extended to +150°C, meeting the control requirements for high-temperature media like steam and molten salt.
Anti-Interference Capability: Equipped with dual-redundant microprocessors and electromagnetic shielding, it maintains signal stability in strong electromagnetic interference environments (e.g., near frequency converters).
Modular Configuration: Adaptable to Diverse Needs
Explosion-Proof Safety Combinations: Optional intrinsic safety (Ex ia IIC T4) and flameproof (Ex d IIC T6) types meet the application requirements for hazardous areas in Zones 0/1/2.
Communication Protocol Expansion: Supports HART 7, Profibus-PA, and FF fieldbus, enabling direct acquisition of over 200 diagnostic data items such as valve stroke and air supply pressure via the fieldbus.
Actuator Compatibility: Compatible with Fisher 657/667, GX series, and third-party actuators, achieving plug-and-play via the NAMUR NE 43/47 interface.
Typical Application Scenarios and Cases
Chemical Production: In a 300,000-ton/year acetic acid project, the DVC6205+DVC6215 combination operated in a +200°C acetic acid vapor pipeline for 3 years with a control accuracy of ≤1.5%, reducing maintenance costs by 30%.
Power Industry: Used for main steam control valves in 1000MW ultra-supercritical units, certified by ASME BPVC Section VIII, with a response time <0.3 seconds to meet the rapid regulation requirements of grid AGC.
Environmental Protection Equipment: In the acid gas treatment system of a waste incineration power plant, it achieves 0.1%-level control accuracy with fluorine-lined control valves, ensuring the emission compliance of pollutants such as SO₂ and HCl.
