STRUCTURE AND FUNCTIONS
The SIDE
Control is suitable for pneumatically actuated
continuous valves with single-acting linear or part-turn
actuators.
Overview
FLUIDIG CONNECTION
VALVE CONNECTION
Connection of the control air
Attachment to a continuous valve wi
actuator acc. to NAMUR
Positioner
The position of the actuator (stroke) is controlled in accordance
with the position setpoint. The latter can be set by an external
standard signal.
Process controller (option)
The SIDE
Control is integrated in a control loop. From the
process setpoint and the process value, the valve stroke is
computed via the control parameters (PID controller). The
process setpoint can be set by an external standard
signal.
Functions
For linear actuators, the following applies in general:
a) Operating mode normally closed when deenergized (NC):
connection of positioning drive
below
b) Operating mode normally open when deenergized (NO):
connection of positioning drive
above
Installation of the valve
• Any orientation, preferably upright.
• Observe the flow direction (general rule for control valves:
flow input under seat!)
• Clean the piping of contamination!
• Before connecting the valve housing, take care that piping
is aligned!
• In the case of weld-on housings, be sure to remove the
actuator before welding.
