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.
