Fluidic connections

The fluidic connections for input and output of the medium to be controlled are
available as standard with G1/4" or G3/8" pipe threads.
The 1/4" connection is only recommended for nominal diameters of the actuator
valve of up to 4 mm.
The controllers are also available to order with medium connections to NPT or RC
standards of the abovementioned sizes or with other connection sizes compatible
with the fluidic data.
ATTENTION!
NOTE
30
For correct functioning of the controller, the medium must first
flow through the sensor block and then through the control
valve. Always observe the direction of the arrow on the sensor
block when connecting the controller!
Because of the elements integrated, special flow conditioning
sections upstream or downstream are not mandatory.
However, in the interest of optimum reproducibility, avoid turns or
narrow bending radii directly at the input of the MFC!
