    • PROBLEM TO BE SOLVED: To provide a valve assembly with a smaller dimension than a conventional standard one to be operated very speedily. SOLUTION: The directly operated pneumatic valve comprises a valve body. The valve body comprises an intake port 30 for feeding pressed air, a cylinder port 32, a valve bore 36 extending in the axial direction inside the valve body, and a valve member 46 capable of moving between prescribed positions inside the valve bore 36. An actuator 14 for moving the valve member 46 in a first direction is attached to the valve body, and an energizing member 66 for applying the energizing force to the valve member 46 in the direction opposite to the first direction is disposed between the valve member 46 and the valve body. In addition, an air assist passage 94 to be operated by combining the valve member with the energizing member 66 is mounted for moving the valve member 46 in the direction opposite to the direction of moving by the actuator 14.
