We exported 7 pcs of 1 inch – 1500 LB-Gate Valves with bellows sealed last week. Bellows are Inconel 625 with min temp series of 485℃. Due to hardness of the material itself and the high pressure, bellows exploded during production. Luckily, the factory fixed the technical problem later. The valves successfully passed the third party's inspection (INTERTEK) and were sent out on time.
