ATI Introduces Electro-Hydraulic Control System

Direct mount system for use with linear and quarter-turn hydraulic actuators

Automation Technology (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 springreturn 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.

The EHCS includes a number of modular options. The control module can include a PLC with valve positioner and sensors for condition monitoring, allowing the user to run Partial Stroke Testing or to gather stroke data during normal operation without scheduling a PST. The EHCS power module is available with a 24 VDC motor, making the system fit-for-purpose in remote solar applications without the additional expense of AC power inverters. If no solar power bank exists on site then the EHCS can be easily fitted with solar panels and batteries. The EHCS power module can also be included with an accumulator as required to meet speed and or power storage requirements.

The ATI electro-hydraulic control system is fully described in a full color brochure. The literature is available in the knowledge center on the ATI website, www.atiactuators.com.
