Abstract
A valve assembly for a wellhead includes a channel extending between a first end and a second end; a valve having a valve closed position in which the channel is blocked and a valve open position in which the channel is unblocked; and a flap arrangement having a flap closed position. The flap arrangement is configured to: displace from the flap closed position in an event of obstruction of the channel; and return to the flap closed position on removal of obstruction from the channel. The valve assembly further comprises a sensor, configured to determine an indication of obstruction of the channel by determining whether the flap arrangement is in the flap closed position.
