An electropneumatic solenoid valve for a pneumatically-actuated field device can include air channels, a flapper valve member, an electromagnetic controller, and a spring. An air supply channel, air dispensing channel and air exhaust channel can be mound into an air chamber. The flapper valve member can include a closure element arranged on an axial control direction and be engageable with a delimitation interior wall mouth of one of the air channels such that the flapper valve member is arranged with a circumferential axial distance to the delimitation interior wall. The electromagnetic controller can displace the flapper valve member in the axial control direction to ventilate/exhaust the air dispensing channel. The spring can bias the flapper valve member into a closed position to close closing the one of the air channels. The flapper valve member can be float-mounted in an unguided configuration except for spring within the air chamber.
