Controlled flow of liquid is conducted between aligned inlet and outlet pipe sections through a valve housing within which a solid valve element is sealed and supported for electrically powered displacement between a fully open position establishing unrestricted flow and a fully closed position blocking inflow from the inlet pipe section and outflow from the outlet pipe section. The valve element is operatively displaced either by rotation or by linear movement under electrically powered control through a valve stem connected thereto, while a manual actuator is also connected to the valve stem outside of the valve housing for imparting reduced dithering displacement to the valve element so as to insure that it is in proper and readied working condition. Such electrically powered operational displacement of the valve element is sensed in response to movement of the valve stem.

Electrically powered valve for controlling, monitoring and evaluating fluid flow

Oil spill polluted water is conducted under pressure in sequence through arator devices to collect and burn a polluted water mixture having its oil concentration increased by extraction of water therefrom during axial flow through the separator devices. Such water extraction is effected by sequential radial outflow through oil flow blocking filter walls of the separator devices in response to rotation thereof.
