Advanced Diagnostics - GE's Masoneilan*
SVI* II AP Digital Valve Positioner
An optional SVI* II AP advanced performance, digital smart valve
positioner provides industry-leading control accuracy and resolution.
A non-contacting position sensor, directly coupled to the valve
shaft, eliminates external linkage to simplify installation. Auto-tune
and auto-calibration features minimize installation and startup
time, while ensuring consistent positioning accuracy. Advanced
diagnostics provide predictive maintenance functionality by warning
of impending problems or failure.
Tailored To Your Application Needs
Three seat types and two face-to-face options allow the
V-Max* contol ball valve to be tailored to your application
needs. Standard MN-7 soft-seat construction provides low
operating torque and consistent Class VI shutoff. Optional
flexible metal seats extend the temperature rating to
316° C (600° F) with Class IV shutoff. The optional heavy-
duty seat provides increased durability in harsher service
environments
