When you design and manufacture products that last and can be maintained to enable additional years of service, then it makes sense to ensure that the correct bolting can removed without damaging the valve body flanges. In the hazardous chemical sector it can be a corrosive environment. Untreated or poorly treated barrier corrosion won’t prevent severe build up of surface damage to bolts, studs and nuts, making them very difficult to remove. At Hunt & Mitton we have been treating our connectors with a Xylan® self lubricating coating, to ensure that corrosion is kept to a minimum and that body parts can be undone for critical inspection and repair if necessary. All of our valves being used on hazardous chemical applications have connectors treated with highly effective self lubricating anti corrosion barrier protection.
