1) Reversible 2x3/2−way valves from Festo (identifier T32F−A, T32N−A, T32W−A) require operating
pressure at port (12) for the pneumatic spring function.
2) Note:
Positions 3 and 4 of the selector plate enable the ducted exhaust of the pilot exhaust air and
venting air if the valve terminal is not equipped with reversible 2x3/2−way valves from Festo.
The seals between the manifold sub−bases and the valves must be mounted in the appropriate
position (see Chapter 5.4.1). Note that the ducted exhaust of the pilot exhaust air and venting via
port (12) does not comply with standard ISO 15407−2 or 5599−2.
