PROBLEM TO BE SOLVED: To improve long-term reliability and individual and mutual finish accuracy of respective parts while reducing material cost and machining cost.;SOLUTION: A valve element 1 for advancing/retreating a valve stem for opening/closing an internal passage, a mounting leg 2 projected to both right and left sides at a lower part, and a union part 3 having a machine outside piping connection part 31 projected to one side, are independently formed and integrated by brazing in a furnace. The union part 3 is integrally provided with a tool engaging part 32 that can engage a tool in machine outside piping connection. The mounting leg 2 is integrally provided with first position regulating parts 71 contacting a noncircular surface 1F of the valve element 1 to regulate the rotating direction position of the mounting leg 2 with respect to the valve element 1, and a second position regulating part 72 contacting a part of the tool engaging part 32 of the union part 3 to regulate the rotating direction position of the union part 3 with respect to the valve element 1.;COPYRIGHT: (C)2013,JPO&INPIT
