As part of Global Supply Line’s Total Valve management program, our ISO 9001 accredited operation can manage your valve re-manufacturing and modification requirements.

With over 30 years experience in valves our staff are experts in all facets of the valve industry. Let us control the refurbishment and modification process for you as part of taking on all your valve management activities.

A repairer who is big enough to re-grind a 750mm (30 inch) ball runs a high overhead operation not suitable for reconditioning a 250mm (10 inch) 150lb gate valve. Activities such as weld overlay repairs, re-cladding and diamond lapping needs to be performed by experienced, qualified contractors. We also work with experts in ceramic valve manufacturing. Control valves and actuators need to be reconditioned by suitably experienced specialists. Global Supply Line are experts in valves, we can arrange to manage your valve repair and modification requirements utilising a network of local and overseas specialist contractors. Depending on the urgency and the type of valve we will appoint the most suitable repairer.
