Industrial Factory Automation

Fluid power valve actuators from Rotork have been installed throughout a liquefied natural gas importing and distribution project that is expected to meet 40 per cent of the demand for gas in Chile. The liquefied natural gas (LNG) complex at Quintero Bay encompasses the installation of a sea terminal to receive LNG from tankers and a plant for regassifying and distribution by pipelines into central Chile. Rotork Fluid Systems has received orders for heavy duty, scotch-yoke pneumatic, gas-over-oil and high-pressure gas actuators, which have been supplied to valve-makers in France, Italy and Spain. The majority of the 87 CP and GP range pneumatic actuators supplied are operating cryogenic service ball and butterfly valves at the Quintero Bay marine terminal and the adjacent storage and regassification plant. The GO range of gas-over-oil and HPG range of high-pressure gas actuators have been supplied for a 28km pipeline that links the Quintero LNG complex to the Electrogas terminal at Qu...

Profibus network-enabled Rotork IQT intelligent electric actuators have been installed to operate butterfly and plug valves on new pipework at a sewage membrane treatment plant. The upgrade involves increasing the number of membrane packs in each tank to 36, increasing the treatment capacity without exceeding the confines of the existing works' footprint. Automation of the treatment process also enables it to run with increased efficiency and reduced energy consumption. On each of the membrane plants, the Rotork IQT actuators operate inlet isolation and outlet modulating valves for the sewage, together with air, sodium hypochlorite and wash water-injection valves. Additional IQT actuators control the permeate isolation valves used for automated sequential flushing to maintain membrane efficiency. In total, 51 actuators are installed on each tank to provide automatic sequencing of the sewage treatment, membrane cleaning and backwashing processes. 14 Profibus-DP two-wire networks li...

Rotork has introduced the Rompak range of electric actuators to offer the marine industry a lightweight solution for the operation of quarter-turn valves and dampers. The range is designed to enable shipboard valve functions to be set-up, controlled and monitored with the same degree of accuracy and flexibility as the most up-to-date process systems. The Rompak actuators retain all the mechanical benefits of the original Rotork Rom design, including self-locking gears, manual override, externally adjustable mechanical stops, a wide range of mains power options and an IP67 watertight enclosure. The Rompak actuator adds a self-contained control package with local controls and status indication relays and the option of Rotork Folomatic positional control, current position transmitter, integral data logger, non-intrusive configuration with a Bluetooth wireless interface and digital bus network connectivity. Network connectivity, which includes Rotork's dedicated Pakscan and the Profib...

Rotork has announced how it has supplied more than 80 ATEX-approved IQPro intelligent electric actuators with factory fitted Profibus cards for the Vopak Skarvik 1 project in Gothenburg. Skarvik 1 is a fully automated petroleum tank storage project 10 new tanks are being constructed and a PLC-controlled SCADA system installed to enable Class 1 hazardous products including petroleum to be pumped to and from any location on the site. Rotork's actuators will take on flow control duties throughout the site, operating gate valves on the tanks and on a new main manifold and pipe rack that will distribute the products around the plant.
