Overview
Rotork CVA fail-safe electric process valve actuators were selected for a critical flow control application in the Australian coal mining industry.
Challenge
Salcan Process Technology manufactures wellhead skids designed for coal mine degassing duties; methane and other flammable gases are extracted from underground coal seams before mining operations begin.
Solution
The installation of actuated control valves was required to control the flow of gas while maintaining back pressure in the coal seam. In operation, back pressure on the coal seam is reduced in a controlled manner to protect the seam, thus maximising gas extraction. For a coal mine this is critical for reducing the risk of an underground explosion; for a gas producer it is critical for maximising the yield.
Result
Rotork CVA actuators were installed for gas flow control, reducing pressure and allowing for the maximum amount of gas extraction.
The successful use of Rotork CVA actuators for similar duties at thousands of remote sites on the Queensland LNG project were an important consideration for the customer in awarding Rotork the project.
Customer Benefits
CVAs play a key role in ensuring safe operation of coal mining, operating on skids that remove flammable gases.
The fail-safe electric positioner package eliminated the need for operators to enter the hazardous area surrounding the valve for set-up and diagnostic functions.
CVA actuators are explosionproof and deliver continuous, repeatable modulating control with a programmable fail-to-position option.

Rotork adds new features to the intelligent IQ3 Pro range
Rotork is excited to announce that new features have been added to the industry-leading IQ3 Pro range of intelligent actuators. The new features include increased speeds for the IQT3F Pro electric modulating actuators, independent open/close speeds for part-turn actuators and closed-loop control for the multi-turn and part-turn actuators.
Rotork: overflowing with ambitious industry solutions
Valve World's Alexandra Kist interviewed our Chief Technology Officer Ross Pascoe, Oil & Gas Managing Director Keith Barnard, and Site Services Director Mike Pelezo.
Hydrogen in the evolving energy market
With the inexorable rate of carbon emissions over the last two centuries, global warming has become an existential threat that demands action. The Paris Agreement set targets to stabilise the world temperature increase to below 2°C, but these aims require dramatic shifts in how we produce and source energy.
The importance of intelligent flow control in valve actuation
The principle behind intelligent actuation and asset management is the concept of the Industrial Internet of Things (IIoT), where, using devices embedded with sensors, electronics and software, data can be collected and exchanged on a large scale to enable improved communication and efficiency.
We welcome Hanbay, Inc. to the Rotork Group
Our acquisition of Hanbay, Inc. based in Montreal, Canada further enhances our product range by adding precise, compact, miniature electric actuators to our portfolio.
Connecting with our digital future
The IQ3 range is renowned for being one of the most robust and intelligent actuators in the industry, and Rotork is excited to introduce the new IQ3 Pro with full mobile App integration. This evolution enables the continual development of new features that drive digitisation and future-proofing of electric actuation.
