Steriflow Valve offers the MK16IQ in three primary
configurations:
• Mark 16IQ-B ‘Basic’ Version: smart positioner
without HART ® protocol with gauge block and
FM Approval (IS) for Class I, Div. 1 locations.
Specify part number 16184.
• Mark 16IQ-S ‘Standard’ Version: same basic
unit but with HART ® protocol capability. Specify
part number 98877.
• Mark 16IQ-FF ‘Foundation Fieldbus TM ’: for ad-
vanced diagnostics with digital communication
and control.
• Other configurations available - contact factory
for Profibus, limit switch module, alarm module
and other accessory ordering information.
Overview
The Mark 16IQ is the "Smart" side mounted positioner
of choice for Steriflow Mark 978 Control Valve models
978SP and Mark 978 INLINE model NSP. This com-
pact, rugged unit offers comprehensive diagnostics
and high level customization with the convenience of
push buttons for in situ configuration or use of a HART ®
communicator.
Operation & Design
The primary module of the Mark 16IQ is the electronic
board comprised of the microprocessor, along with the
indicating and control elements. The unit is designed
so that optional modules for alarms and position feed-
back are easily plugged in or snapped on.
The current command (which typically serves as the
power supply to the instrument) is compared to the
internal position feedback signal. By comparing the
input and feedback signals, an adaptive controller de-
termines the positioning signal, which follows an opti-
mized algorithm. The parameters for this algorithm are
determined from valve and actuator characteristics
analyzed during initialization and as modified during
the real-time performance of the actuator. The MK16IQ
will identify and optimize each valve’s specific perfor-
mance characteristics.
The positioning signal controls piezo electric solenoid
valves which respond based on the size of the control
deviation. The resultant actuator pressure can be mod-
ified to adapt the response time to the actuator size.
Two binary inputs are standard and allow the logical
linkage of the binary input signals with alarm reports,
or positioning the actuator at its fail-safe position.
If the "standard" Mark 16IQ is chosen with your valve
selection, configuration and diagnostic information can
be accessed via PC or HART ® handheld communica-
tor. Additionally, all settings and diagnostic information
can be called up locally at the positioner via the push
buttons located inside the cover of the unit. The Analog
Positioning Module supplies an analog 4-20 mA feed-
back signal, while the Binary Module supplies stroke
and alarm reports.
