Hydraulic valve actuator HPG

linearScotch yokedouble-acting

HPG actuators are designed to use pipeline gas as the motive power source. Using our industry recognised and proven hydraulic scotch-yoke quarter-turn design, the HPG is a direct gas actuator customisable to end-user specifications. Our actuators are complemented with a variety of Rotork designed and manufactured high-pressure gas controls. Features • A separate cylinder for hydraulic override ensures complete separation of high-pressure pipeline gas from the hydraulic fluid • Independent override cylinder allows replacement of power cylinder seals without removal of the actuator from the valve and allows manual operation while the power cylinder is disassembled • Control configurations are available to meet virtually any operation requirements • PED or ASME approved gas/oil and power gas storage tanks • Speed control in both directions standard • Extremely wide range of high-pressure control logic options • Complies with EN60529 (1991) + (A1:2000) for IP67M • Actuators certified to ATEX 2014/34/EU • Actuators certified in accordance with PED 2014/68/EU
