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).
Per duct, either a fixed flow restrictor or a check valve can be installed.
