A pneumatically controllable valve assembly, in particular for use in a tire inflation system, includes a first fluid port, a second fluid port, and a movable member configured to be moved between an open position and a closed position. When the movable member is in the open position the first fluid port is in fluid communication with the second fluid port. When the movable member is in the closed position the first fluid port is fluidly isolated from the second fluid port. A first pneumatic actuator is in fluid communication with the first fluid port. The first pneumatic actuator is configured to bias the movable member toward the open position. A second pneumatic actuator is configured to bias the movable member toward the closed position. The valve assembly also includes a flow restrictor. The first fluid port is in fluid communication with the second pneumatic actuator by way of the flow restrictor, at least when the movable member is in the open position.
