The invention relates to a pneumatically controllable valve assembly (48), in particular for use in a tire inflation system (12), the valve assembly (48) comprising: a first fluid port (51); a second fluid port (52); a movable member (53) configured to be moved between an open position and a closed position, wherein when the movable member (53) is in the open position the first fluid port (51) is in fluid communication with the second fluid port (52), and wherein when the movable member (53) is in the closed position the first fluid port (51) is fluidly isolated from the second fluid port (52); a first pneumatic actuator (63a) in fluid communication with the first fluid port (51), the first pneumatic actuator (63a) configured to bias the movable member (53) toward the open position; a second pneumatic actuator (63b) configured to bias the movable member (53) toward the closed position; and a flow restrictor (65); wherein the first fluid port (51) is in fluid communication with the second pneumatic actuator (63b) by way of the flow restrictor (65), at least when the movable member (53) is in the open position. The invention further relates to a tire inflation system (12) comprising the valve assembly (48) and to methods of operating the valve assembly (48) and the tire inflation system (12).
