A fluid-flow valve suitable for isolating or controlling the flow of fluid in a process line comprises a valve body (8) having a fluid-flow passage (9) therethrough, a valve member (5) movable to modify the flow of fluid through the passage and an access channel (15, 19, 20, 24, 28, 29) in the valve permitting monitoring of a characteristic (for example temperature, pressure or flow-rate) of fluid flowing through the fluid-flow passage. |
