Automation Technology (ATI) has introduced an electro-hydraulic control system (EHCS), adding to its range of valve actuators and controls. The product can be directly mounted to a linear or quarter-turn spring-return or double-acting actuator to perform critical shutdowns even when a power source is unavailable. The EHCS can be provided for either non-hazardous area or hazardous area rated service. The EHCS consists of a power module and a control module. The power module includes an electrical motor, a single-direction hydraulic pump with reservoir, a valve manifold, and a power supply for control components.
