Masoneilan SVI™ II AP Advanced Performance Digital Valve Positioner (HART)
The Baker Hughes SVI™ II AP (Smart Valve Interface, Advanced Performance) is a 32 bit microprocessor digital valve positioner with a local interface that controls a pneumatic actuator using a two-wire 4-20mA control signal. The instrument offers bi-directional communication using the HART® protocol. Its universal design offers ease of retrofit in place of existing analog positioners on Masoneilan or non-Masoneilan pneumatic actuators, either single-acting or double-acting.
