A sliding gate regulator includes a valve body having a fluid inlet and a fluid outlet connected by a flow corridor. An opening is disposed in the valve body, the opening being oriented substantially perpendicularly to the flow corridor. A stationary plate and a slidable gate are disposed within the flow corridor, the slidable gate and the stationary plate cooperating to control fluid flow through the flow corridor. A removable plug is disposed within the opening in the valve body, the removable plug providing access to the stationary plate and to the slidable gate.
