ATI introduces electro-hydraulic control system
12 October 2017
Texas-headquartered Automation Technology Inc (ATI) has introduced an electro-hydraulic control system, adding to its broad 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. The 24 VDC electrical control system includes a pump pressure switch, open/off/close and auto/manual selector switch and limit switch relays. Standard electro-hydraulic control systems operate at 2800 psi, allowing for operation of any actuator with a minimum supply pressure up to 2500 psi.
