An electro-hydraulic valve is electrically powered to maintain an open condition to allow unrestricted hydraulic flow through the pump during normal operation. In the event of an elevator malfunction, electrical power is terminated to the valve, causing the valve to close and thus requiring all hydraulic fluid to pass through a restrictor. The restrictor limits the flow of hydraulic fluid through the hydraulic pump, thus limiting its rotational speed and the rotational speed of the elevator drive motor to which it is attached, thereby allowing the elevator to descend at a safe speed.12-23-2010
