Descripción de producto
Masoneilan SV II AP Advanced Performance Digital Valve Positioner SVI2-21123111
Product Overview
  1. 32-bit microprocessor-based digital valve positioner with HART 5/7 protocol over 4-20mA signal, delivering high-precision pneumatic actuator control and real-time online diagnostics.
  2. Features non-contact through-housing position sensing and built-in LCD pushbutton interface, supporting safe local configuration in certified hazardous areas without removing the enclosure.
  3. Universal modular design compatible with both Masoneilan and third-party single-acting linear/rotary valves, serving as a direct drop-in replacement for traditional analog positioners.
Technical Specifications
Parameter Specification
Input Signal 4-20mA with HART 5/7 bidirectional communication
Supply Pressure 20 – 150 psi (1.4 – 10.3 bar)
Operating Temperature -50°C to +85°C
Pneumatic Action Single-acting, fail-safe
Application Industry
  1. Oil & Gas / Petrochemical: Suitable for wellhead control, pipeline transmission and refining processes in explosive hazardous zones.
  2. Power Generation: Delivers stable flow regulation for boiler feed water, steam circulation and cooling water systems in thermal/nuclear power plants.
  3. Chemical & Pharmaceutical: Supports precise process control for corrosive media, batch production and strict safety-compliant manufacturing lines.
Common Problems & Solutions
  1. Valve position drift / calibration inaccuracy: Run auto-tune and auto-stop calibration via local LCD or HART host; verify stable supply air pressure.
  2. Slow response / blocked air vent: Clean the exhaust port to remove dust and condensate; inspect the air filter regulator for clogging.
  3. HART communication failure: Check 4-20mA loop wiring and power supply; confirm device address and cable shielding integrity.
Replacement Models
  1. SVI2-21123121: Same base configuration with additional valve position feedback signal output.
  2. SVI2-22123111: Double-acting pneumatic version with LCD display, for dual-acting actuators.
  3. SVI3 AP: Next-generation upgraded model with enhanced advanced diagnostics and wider environmental adaptability.
