The Baker Hughes SVI™ II AP (Advanced Performance Smart Valve Interface) features a high-precision 32-bit microprocessor-based digital valve positioner equipped with an on-site local interface. Designed for pneumatic actuator regulation, the device operates via a conventional two-wire 4-20mA control loop and supports full bidirectional data communication through the HART® protocol. Boasting a versatile and universal structural design, this positioner enables seamless retrofitting and direct replacement of conventional analog positioners. It is fully compatible with both Masoneilan and third-party pneumatic actuators, covering all single-acting and double-acting application scenarios.
