Chapter 2 GATE DESIGN
After completion of assembly, all seating and wedging surfaces should be cleaned thoroughly of all
foreign materials and final adjustments made. The gate should then be operated from fully closed to
fully open position to verify that the assembly is functioning properly. Where electric motor actuators
are provided, the complete assembly of penstock and actuator should be tested.
