The Masoneilan SVI™ II AP (Smart Valve Interface, Advanced Performance) is a digital valve positioner equipped with a 32-bit microprocessor. It features a local interface that manages a pneumatic actuator through a two-wire 4-20mA control signal. This device supports bi-directional communication via the HART® protocol. Its universal design facilitates easy retrofitting to replace existing analog positioners on both Masoneilan and non-Masoneilan pneumatic actuators, accommodating both single-acting and double-acting configurations.

 

Masoneilan SVI™ II AP Advantages:

Non-Contact Position Sensing Technology:

• Sensing occurs through the housing, eliminating mechanical moving parts from the main housing cavity, thereby extending the device’s lifespan.

• The mounting process is straightforward.

 

Easy, Simple, Accurate:

• The LCD and pushbuttons are functional in all certified hazardous environments.
• Commissioning is quick and precise, utilizing auto stops and auto-tune methods.
• A single design is adaptable for various applications, including rotary or linear configurations, and can be operated remotely or locally.
