VALVE REPAIR AND TESTING EQUIPMENT

Serving the World For more than 30 years it has been EFCO’s policy to win our customers as partners. Thus we can jointly solve your problems which arise during machining and testing of sealing faces and flanges on valves. Experience has shown that preventative maintenance is the cheapest way of increasing the safety of your installations. Once the first faults occur, costs frequently balloon, especially as action has to be taken under enormous time pressure in such cases. In addition to environmental damage and high clean-up costs, unquantifiable damage to your image can also quickly arise....
