ASCO Solenoid Spool Valves and Masoneilan SVI II AP Svi2 Intelligent Digital Valve Positioner Controller

The Masoneilan SVI II AP (Smart Valve Interface, Advanced Performance) from is a high-performance digital valve positioner designed for precise control of pneumatic actuators in industrial processes. This 32-bit microprocessor-based device operates on a two-wire 4-20 mA loop with HART communication, offering bi-directional interaction for setup and diagnostics. Available in standard and high-flow variants (Cv up to 2.2), it supports single-acting actuators and features non-contact position feedback for enhanced reliability. Compliant with SIL 2 standards, it's field-upgradable and suitable for linear or rotary valves, ensuring optimized performance across various actuator sizes while often eliminating the need for additional boosters.

• High Flow Capacity: Cv 2.2 for rapid actuator response, reducing or eliminating boosters/quick exhausts; air delivery up to 102 scfm at 90 psi.
• Non-Contact Position Sensing: Field-proven sensor with no moving parts, SIL 2 compliant (IEC 61508), and resolution of 0.0015%.
• Advanced Diagnostics: Standard includes 5 pressure sensors, travel/cycle tracking; advanced adds offline signatures via ValVue Suite, online monitoring with Valve Aware.
• User Interface: Explosion-proof external LCD with buttons; setup wizard for quick commissioning; local/remote operation.
• Communication and Integration: HART Revision 6; supports eDDL, DTM, ValVue software; integrates with DCS/asset management systems.
• Rugged Design: Aluminum housing with grey polyurethane paint (ISO 12944-2 C4); IP66/NEMA 4X; -50°C to 85°C operating range.
• Options: Position retransmit (4-20 mA), limit switches, remote-mount sensor (up to 30m), field-upgradable firmware/diagnostics.

Ideal for oil & gas, chemical, petrochemical, and power industries where precise valve positioning is critical. Used in surge-control, throttling, and safety applications with linear/rotary valves. Supports Masoneilan and non-Masoneilan actuators, enhancing process control in harsh environments with vibration, corrosion, or extreme temperatures.

• How does the high-flow option benefit large actuators? It provides higher air capacity (Cv 2.2), enabling faster response without additional boosters, reducing installation complexity.
• What diagnostics are available? Standard: pressure sensors, travel/cycles; Advanced: offline signatures, online health monitoring via ValVue or DTM.
• Is it compatible with existing systems? Yes, retrofits analog positioners; supports HART for DCS integration; universal mounting for linear/rotary.
• How to commission? Use the setup wizard via LCD/buttons or ValVue software; auto-calibration for position sensor.
• What hazardous area certifications does it have? ATEX, FM, CSA, IEC for intrinsic safety, explosion-proof, flame-proof, and nL.
