Abstract
A device () for controlling the flow of a fluid through a conduit () from an upstream side () to a downstream side (). The device includes a housing () having one or more valve apertures () through which the flow of fluid is selectively controlled. A valve member () is mounted on the housing and arranged to move reciprocally to selectively open and close the one or more valve apertures. A seal () is arranged at or beyond a position the valve member reaches when the one or more valve apertures are all closed. The device also includes a resilient member () that acts to bias the seal towards the valve member.
