Abstract
A valve such as penstock with a gate (13) which slides across an opening in a frame (10, 11, 12). On at least one side of the gate (13) is a two-part sealing strip consisting of resilient layer (22) and a superimposed bearing portion (23). Attached to or integral with bearing portion (23) is a thickened part (24) which limits the maximum compression of the resilient layer (22) when the valve is closed.
