Manifold sub-base
Fig. 2.3 Check valve – example of a check valve for the 14 mm size
A check valve can be integrated between sub-base and valve to prevent unintended switching of actuat­
ors in response to high back pressure in the exhaust air ducts (3) and (5). If there is a high level of back
pressure, the check valves seal off exhaust air ducts (3) and (5).
