Claims

[Scope of utility model registration request]

A valve body chamber is formed in a part of the communication orifice between the suction port and the discharge port, and the valve body is slightly inserted into the valve body housing recess at the end of the valve body holding member, facing the valve seat configured at the end of the orifice. The valve body holding member is supported so as to be slidable freely, and the valve body holding member is fixed to a movable end of an electromagnetic mechanism that is elastically biased by a predetermined pressure in a direction in which the valve body abuts the valve seat. A solenoid valve for chemical liquids, characterized in that a valve body chamber is sealed by a diaphragm whose effective diameter is smaller than the closing area of the valve body and valve seat.
