とを特徴とする遠隔操作型減圧弁。 The pilot consists of a main valve part, a pilot part, and a drive part, and the drive part receives the supply pressure controlled by the pilot part, opens and closes the main valve of the main valve part, and maintains the secondary side pressure almost constant. In the actuated pressure reducing valve, the pilot portion includes a bellows facing the pilot valve stem, a secondary pressure detection hole that connects the bellows chamber consisting of an outer space or an inner space of the bellows, and an outlet, and an inner wall in the bellows. A control fluid chamber for applying a control force in the same direction as the bellows spring to a pressure-receiving face plate of the bellows is formed on a side opposite to the bellows chamber with respect to the bellows. Remotely operated pressure reducing valve.
