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

Masoneilan SVI II AP is an advanced digital positioner leveraging a 32-bit microprocessor for precise pneumatic actuator control via 4-20 mA HART signals. Its non-contact Hall-effect position sensor ensures high resolution (0.0015%) and SIL 2 compliance, while the high-flow option (Cv 2.2) supports large actuators without boosters. Designed for retrofit on single/double-acting valves, it features robust electronics and field-upgradable firmware for long-term adaptability in demanding industrial settings.

• Pneumatic System: Two-stage relay with high Cv for dynamic response; air/sweet natural gas compatible; filtered/regulated supply.
• Position Feedback: Non-contact sensor (no mechanical wear); remote-mount option with cabling up to 30m.
• Diagnostics Upgrades: From standard (pressure, cycles) to advanced (signatures, friction analysis) via firmware; 5 sensors for real-time data.
• Communication Protocol: HART 6 with eDDL/DTM; wireless/open technologies; plug-in electronics module.
• Safety and Durability: IEC 61508 SIL 2; encapsulated electronics; stainless steel components; EMC compliant.
• Mounting Flexibility: Universal for linear (6.4-100mm+) or rotary (18-140°); 300-series stainless steel kits.
• Output Options: 4-20 mA position retransmit; two isolated solid-state switches; configurable via software.

Engineered for high-precision control in petrochemical refineries, upstream oil & gas, and chemical processing plants. Excels in applications requiring fast response to setpoint changes, such as compressor anti-surge or emergency shutdown systems, where non-contact sensing minimizes downtime.

• What is the air consumption at different pressures? 0.28 scfm at 30 psi; 0.35 scfm at 45 psi for single-acting.
• How to upgrade diagnostics? Field-upgradable via firmware; use ValVue or DTM to switch from standard to advanced levels.
• Does it support remote communication? Yes, via HART; integrates with PRM Plug-in or AMS ValVue SNAP-ON.
• What actuator types are supported? Single-acting pneumatic; linear/rotary motion per mounting kits.
• How to handle firmware updates? Compatible with versions 3.1.x to 5.1.x; update using ValVue 2.4+ software.
