Gate Valve vs Ball Valve Working Mechanism. A gate valve employs a gate to control the medium flow. Gate is a solid disk that is connected to a stem, acting as a barrier. Gate valves are commonly operated by an actuator, handwheel. The actuator is connected to a valve stem and transmits rotational energy to it.
