Product Overview
The Masoneilan SVI II Valve Positioner Package is a complete valve control assembly supplied with the positioner body, mounting bracket, feedback assembly, pressure gauges, filter regulator, tubing, fittings, terminal block, manual, calibration certificate, and a 12-month warranty. It is pre-assembled and pre-tested at the factory, which shortens on-site commissioning and removes the need to source and match separate components. The package accepts a 4-20 mA DC input signal and supports HART communication for configuration, calibration, and diagnostics. It delivers accurate pneumatic output for valve stroke control and includes travel feedback for dependable position monitoring. Local adjustment, auto calibration, and diagnostic alarms help keep the valve loop stable during daily operation. The design supports both new installations and retrofit projects, helping maintenance teams standardize spare parts and reduce downtime.
The enclosure is built for industrial environments and protects internal electronics from dust, water, and vibration. It operates reliably across a wide ambient temperature range and accepts common instrument air supply pressures. Control options include local calibration, remote configuration, and diagnostic reporting. The package is suitable for chemical, petrochemical, oil and gas, power, water, and general process industries. Its modular design reduces maintenance effort and supports long-term reliability with predictable spare parts planning. Every package is backed by a 12-month warranty.

Application Industry
Chemical processing
Petrochemical refining
Oil and gas production
Power generation
Water and wastewater treatment
Pharmaceutical manufacturing
Food and beverage processing
Pulp and paper
These industries require accurate valve positioning, stable HART communication, and dependable diagnostics. The package performs well in humid, dusty, and vibrating plant environments when installed and maintained correctly. It supports flow, pressure, and level control loops that use pneumatic control valves.
Common Problems
Valve does not move: check 4-20 mA signal, air supply, and actuator linkage.
HART communication failure: verify loop wiring, power, and device address.
Valve hunting: inspect tuning, air supply stability, and actuator sizing.
Air leakage: check fittings, gaskets, and relay assembly.
Incorrect feedback: inspect feedback linkage, magnet, and calibration.
Diagnostic alarm: review HART diagnostic data, supply pressure, and valve friction.
Zero drift: confirm mounting stability and recalibrate.
Moisture in air line: service filter regulator and install dryer if needed.
Manual override issue: check bypass, linkage, and actuator spring.
Output pressure error: inspect I/P converter, nozzle, and relay.
All units are backed by a 12-month warranty.
