Abstract
A differential pressure control valve has a valve seat made of magnetic material, a valve body, and a guiding member fixed to the valve seat to guide the valve body. The valve body is located on the downstream side of the valve seat, and is seatable on the valve seat in accordance with the pressure difference between the upstream side and the downstream side to selectively open and close a valve hole. The valve body has a lid made of magnetic material and a guided member made of nonmagnetic material. The lid is seated on the valve seat to close the valve hole, and the guided member is guided by the guiding member. The valve seat or the lid has a permanent magnet, located outside the area where the valve body is seated on the valve seat, urging the valve body in the direction approaching the valve seat.
