Pressure regulator plates
Fig. 9: Pressure regulator plate
A pressure regulator plate with adjustable pressure regulator can be installed between the manifold
sub-base and the valve in order to control the force of the connected actuators. The pressure regulator
maintains a constant output pressure (secondary side) independent of pressure fluctuations (primary
side) and air consumption.
Some components of the vertical stacking are only available in single widths.
Identification of the pressure regulator plates
ID codes are printed on the sides of the pressure regulator plates. The ID codes enable equipment
items on the valve terminal to be identified.
