Available Mounting
DVC6000 HW2 digital valve controllers can be
mounted on Fisher and other manufacturers rotary
and sliding‐stem actuators
DVC6005 HW2:
Base unit for 2 inch pipestand or wall
mounting
J
DVC6015:
Remotely mounted feedback unit for
sliding‐stem applications
J
DVC6025:
Remotely mounted feedback unit for
rotary or long‐stroke sliding‐stem applications or
J
DVC6035:
Remotely mounted feedback unit for
quarter‐turn rotary applications
Mounting kit required for mounting feedback unit on
actuator
Mounting the instrument vertically, with the vent at
the bottom of the assembly, or horizontally, with the
vent pointing down, is recommended to allow
drainage of moisture that may be introduced via the
instrument air supply.
