Masoneilan Positioner SVI™ II AP Advanced Performance Digital Valve Positioner (HART)

The Masoneilan positioner 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.

Features of Masoneilan Positioner SVI™ II AP

  • Sensing through the housing, no mechanical moving parts entering the main housing cavity, prolonging the life
  • Simple mounting procedure
  • LCD and pushbuttons operable in all certified hazardous environments
  • Quick and accurate commissioning with auto stops and auto tune methods
  • One design fits many applications: Rotary or Linear; Remote or Local
  • Built-in diagnosis of the valve’s health condition allows for the necessary and recommended spare parts to be ordered in good time and these can be ready for the next scheduled stop. This avoids an unfortunate prolonged production or process stoppage in time
  • The positions can be used for both linear and rotary valves
  • Supplied as standard with aluminum housing. Stainless steel on request
  • Have many certifications including ATEX
  • There is a large selection of fittings so that the positions can be adapted to existing valves, including valves from other suppliers
