Abstract (en)

[origin: EP2796727A1] It is an object of the present invention to provide a dew condensation preventing valve for preventing occurrence of dew condensation in a pneumatic actuator while effectively using air in the pipe. A dew condensation preventing valve 30a is applicable to a pneumatic system 10 having a pneumatic actuator having a pressure chamber to which compressed air is supplied. A valve housing 31 has an air intake port 33 and an air discharge port 34, which open into pressure chambers 17a and 17b, an on-off valve assembly 36 is reciprocable between a forward limit cutoff position and a backward limit cutoff position, and configured to prevent the air intake port 33 and the air discharge port 34 from communicating with each other at the forward limit cutoff position and the backward limit cutoff position. When the on-off valve assembly 36 is being moved between the forward limit cutoff position and the backward limit cutoff position, the air intake port 33 and the air discharge port 34 communicates with each other, and air in the pressure chambers 17a and 17b is partially discharged to the outside.
