Claims

[Scope of utility model registration request]

A valve body in which a fluid inlet and an outlet are formed, a valve element that comes into contact with and separates from a valve seat installed in the valve body, a valve stem that operates this valve element, and an actuating force applied to this valve stem. an electromagnetic coil provided in the valve box to provide a pressure, a pressure receiving part to which fluid pressure is introduced to actuate the valve stem toward the valve seat, and a pressure receiving part that moves the valve stem in a direction in which the valve body moves away from the valve seat. A valve device comprising: a biasing spring;
