Fluid control valve

A fluid control valve that adjusts a flow rate of fluid introduced from an upstream side thereof to allow the fluid to be delivered downstream, comprising:

• a body having a flow passage of the fluid formed therein;
• a first valve seat and a second valve seat arranged in the body along the flow passage;
• a valve element having a first valve portion and a second valve portion which are formed integrally therewith, the first valve portion and the second valve portion being capable of moving to and away from the respective first valve seat and second valve seat, approximately simultaneously, the valve element moving forward and backward within the body while being supported therein, to thereby adjust a flow rate of the fluid allowed to be delivered downstream according to a lift amount of each valve portion from the valve seat associated therewith;
• and
• a pressure-canceling structure including a valve-opening pressure-receiving surface for receiving a pressure of the fluid acting on the valve element in a valve-opening direction, and a valve-closing pressure-receiving surface for receiving a pressure of the fluid acting on the valve element in a valve-closing direction, the pressure-canceling structure canceling at least part of the pressure of the fluid acting on the valve element.
