Abstract

PURPOSE:To have possibility of surface pressure adjustment for both metal seats at the time of valve closing by furnishing at least either of the metal seats on the valve element side and valve chest side with an elastical flexible deformable construction with location adjustment mechanism. CONSTITUTION:A gap L1 is formed between the valve element 6 and a coupling part of a flanged seat part 5b of the valve element side metal seat 5 and a bolt 10 working as a location adjustment mechanism A with lock nut is screwed fast to the seat part 5b in such a manner as the formost part being pressed against the valve element 6. This makes it possible for screwing of the coupling bolt 9 and thrusting bolt 10 to make locational adjustment of the idle end of the cylindrical seat part 5a of the valve element side metal seat 5, which is on the idle end side, in the radial direction of the valve element and then to make fixation.
