Coriant, the UK-based industrial and infrastructure maintenance services company backed by HIG Capital, has acquired Control Valve Services (CVS) for an undisclosed sum. The deal marks Coriant's fourth acquisition since its January 2026 launch, when HIG merged Rainham, Zenith, and Tei to create the group. The combined entity now generates approximately £200 million ($267.6 million; €230.9 million) in revenue.

CVS specializes in control valve maintenance and refurbishment, serving international blue-chip clients in high-performance industrial environments from its West Yorkshire headquarters. The acquisition strengthens Coriant's capabilities in critical infrastructure maintenance across sectors including energy, utilities, and manufacturing. Adam Taylor, non-executive director of Coriant and principal at HIG, emphasized that CVS's specialist skillset and established customer relationships complement Coriant's existing footprint.

This latest acquisition demonstrates HIG's aggressive consolidation strategy in the industrial services sector. By integrating complementary specialists like CVS, Coriant aims to expand its end-to-end service offerings across the full asset lifecycle. The deal positions Coriant as a more comprehensive provider of installation, maintenance, refurbishment, and decommissioning services for critical infrastructure.
