A reservoir pen includes a nib, a feed bar defining an ink channel and having an ink port, and a valve for controlling flow of ink from the ink port to an underside of the nib. The valve includes a seat, a valve member, and a resilient element engaging the valve member to bias the valve member away from the ink port toward an open position. The valve member is further positioned to engage the nib to urge the valve member against the resilient element and into sealing contact with the seat. The resilient member is disposed outside of the ink channel in at least the open position.
