Product Description Product DescriptionProduct Overview of Masoneilan SVI2-21123121 Valve PositionerThe Masoneilan SVI2-21123121 is a high-performance digital valve positioner from the SVI? II AP (Advanced Performance) series, designed for precise control of pneumatic actuators in demanding industrial environments. Utilizing a 32-bit microprocessor, it supports HART 5/7 communication over a 4-20mA control signal, enabling bidirectional data exchange for remote monitoring and diagnostics. Its universal design allows easy retrofitting on both Masoneilan and non-Masoneilan actuators (single- or double-acting)Masoneilan SVI2-21123121 Valve Positioner: Key Features and Selling Points:The Masoneilan SVI2-21123121 Advanced Performance Digital Valve Positioner is a cutting-edge solution designed for precise control and optimization of pneumatic actuators in demanding industrial environments. Combining robust engineering with advanced diagnostics, this valve positioner stands out for its versatility, reliability, and integration capabilities. Below is a detailed overview of its features and competitive advantages.Detailed Photos 1. Non-Contact Position Sensing TechnologyThe SVI2-21123121 employs non-contact Hall-effect sensors to measure valve position without mechanical components, ensuring longer service life and reduced wear. This technology provides 0.00015% resolution for ultra-precise positioning, critical for applications like steam regulation and process control. Its magnetic coupling system uses rare-earth magnets, maintaining strength over decades, while shielding against electromagnetic interference2. Advanced Diagnostics and MonitoringThree-Tier Diagnostics:Continuous Diagnostics: Monitors valve cycles, travel distance, runtime (open/close), and critical alerts (e.g., position deviation, supply pressure issues) Offline Diagnostics: Includes valve response tests, actuator pressure analysis, and high-resolution Valve Signature Testing to quantify friction, spring performance, and seat condition Online Diagnostics: Real-time monitoring of valve position, I/P pressure, and board health via HART? protocols. With Valve Aware software, it measures KPIs like hysteresis, response time, and friction without interrupting operations Field-Upgradable: The SD (Standard Diagnostics) version can be upgraded to AD (Advanced Diagnostics) to unlock features like valve seat load analysis and embedded performance charts3. Rugged Design for Harsh EnvironmentsDurable Construction: Available in low-copper aluminum (ASTM 360) or 316L stainless steel housings, resistant to corrosion, vibration, and extreme temperatures (-50°C to +85°C). The pressurized electronics compartment prevents moisture ingress Explosion-Proof Certification: Complies with ATEX, FM, IECEx, and regional standards (e.g., China, Russia), ensuring safe operation in hazardous areas. The optional explosion-proof LCD allows local calibration without exposing wiring 4. Universal Compatibility and Ease of UseBroad Application Support: Suitable for linear and rotary valves, single- or double-acting actuators, and remote/local installation. It integrates seamlessly with Masoneilan and non-Masoneilan actuators, reducing retrofitting costs Quick Commissioning: Features auto-stop for zero/span calibration and auto-tune algorithms to optimize valve response. The optional LCD interface simplifies setup and troubleshooting in hazardous zones Modular Design: Replaceable components (e.g., I/P relay, circuit boards) enable maintenance without full disassembly, minimizing downtime 5. Integration and Communication FlexibilityHART? 7 Protocol: Enables bidirectional communication for remote configuration, diagnostics, and firmware updates. Compatible with eDDL, FDT/DTM, and asset management systems like ValVue? Suite Low Power Consumption: Operates at 9Vdc (20mA loop), compatible with legacy systems and wireless HART adapters like Masoneilan VECTOR Auxiliary Outputs: Two configurable solid-state switches (24Vdc, 1A) for alarms or control signals, reducing the need for external accessories 6. Industry-Specific Advantages·Wide Supply Pressure Range: Supports 20-150 psi for double-acting actuators, ideal for high-pressure applications in oil & gas, refining, and power generation .·High Air Delivery: A flow capacity of 280 SLPM @ 30psi ensures rapid actuator filling/venting, critical for emergency shutdowns or dynamic control .ConclusionThe Masoneilan SVI2-21123121 excels in precision, durability, and adaptability, making it a top choice for industries prioritizing process efficiency and safety. Its advanced diagnostics, universal compatibility, and explosion-proof certifications position it as a future-proof investment for complex valve automation challenges.
