Smart Valve Positioners
Accessories Mark 16IQ Smart Valve Positioners
The MK16IQ is an intelligent positioner offering
precision control of both rotary and linear style control
valves. This compact, yet rugged unit offers comprehensive
diagnostics and high level customization with
quick configuration and simple ease of use.
OPERATION & DESIGN
board comprised of the microprocessor, along with the
indicating and control elements. The unit is designed
so that optional modules for alarms and position
feedback 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
determines the positioning signal, which follows an
optimized 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 performance
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
modified 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.
HART communication can be conducted via PC or
HART handheld communicator. 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 feedback signal,
while the Binary Module supplies stroke and alarm
reports.
Jordan Valve offers the MK16IQ in three primary
configurations:
‘Basic’ Version: smart positioner only without
gauge block, Hart protocol or hazardous location
approvals. Specify part number 17876.
‘Standard’ Version: same basic unit but with
HART protocol, gauge block and FM Approval
(IS) for Class I, Div. 1 locations. Specify part
number 98877.
Profibus PA/Foundation Fieldbus: for advanced
diagnostics with digital communication and
control.
Other configurations available - contact factory
