To avoid long isolation periods this is done in situ. For example, if a valve is unserviceable (or is part of a maintenance programme) and requires refurbishment, our engineers can strip down a valve and carry out a refurbishment to the internal parts as required. The valve is then reinstated with new parts as necessary. HVL specialise in the overhaul, maintenance of valves offering a friendly personal service and customised to meet specific clients requirements. HVL offer a high quality service on valve repairs In-Situ and can also remove them away from site to our engineering workshop for a full overhaul. No matter the size of the valve, our aim is to repair your valves to the highest possible standards thereby minimising your downtime and costs.
