<p>A pressure reducing valve, wherein a diaphragm rod is held, through a diaphragm retainer, on a diaphragm held between a body and a cover, a valve element capable being seated on a valve seat fixedly disposed in a body with its valve hole opened to the center part thereof is installed at the middle part of a valve stem having one end part detachably connected to the diaphragm rod, and the other end part of the valve stem is slidably fitted to a guide hole formed in the body. A valve operating unit (120) formed by pre-assembling a valve seat member (100) having the valve hole (111) and the valve seat (112), a guide member (106) having the guide hole (105) and press-fitted into the valve seat member (100), and the valve stem (114) having the valve element (113) with each other is installed in the body (34) so that one end part of the valve stem (114) is projected from the valve hole (111) and the other end part of the valve stem (114) is slidably fitted to the guide hole (105). Thus, machining cost can be reduced and fittability can be increased.</p> |
