PURPOSE: A pneumatic solenoid valve is provided to be firmly fixed to an external device like a vehicle by directly connecting a bolt to a mold with a bolt fastener. CONSTITUTION: A pneumatic solenoid valve comprises solenoid(10), a mold(20), a vacuum port(30), an atmospheric pressure port(40), a discharge port(50), a valve member(60), and a bolt fastener(70). The solenoid has a bobbin, on which coil has been wound. The mold shields the solenoid. The vacuum port is integrally installed on the mold, and vacuum pressure from the outside is applied to the vacuum port. The atmospheric pressure port supplies external atmospheric pressure to the inside of the bobbin. The discharge port is communicated with the atmospheric port and the vacuum port.
