For speed control of hydraulic elevators, inverter control systems have good characteristics for saving energy and improving efficiency. This paper describes a newly developed special valve for hydraulic elevators controlled by an inverter. This valve has two channels of a pilot circuit with a check valve. One is for normal use, and the other is for backup in case of an emergency such as a blackout. Simulations and experiments were carried out on the effects of the deceleration adjuster in the emergency pilot circuit, and it was confirmed that the car could be safely stopped.
