Claims

[Scope of utility model registration request]

A pair of airtight chambers arranged side by side; A high-pressure port, a low-pressure port, and a supply port facing each other, which are opened in the pair of airtight chambers; and a supply port provided in each airtight chamber; a pair of valve arms that close one of the low pressure ports and open the other; and an actuator that simultaneously operates the pair of valve arms in the same direction. a top case and a lower case for forming an airtight chamber; a seal ring sandwiched between the top case and the lower case, the seal ring having a defining rib defining a pair of airtight chambers in an intermediate portion thereof; ; A substantially U-shaped valve arm that is inserted in the middle part of the seal ring in the thickness direction corresponding to each airtight chamber and is connected integrally on the outside of the airtight chamber; It is characterized by comprising an integral covering made of the same material as the seal ring formed on the front and back sides; and a valve body formed by a part of this covering for opening and closing the high pressure port and the low pressure port. A control valve with a pair of airtight chambers.
