<p>The electromagnetic valve has a valve housing (4) enclosing a valve slider (6) contained within a housing bore (13) and a pair of electromagnets (2) for controlling the valve movement between 2 alternate end positions, the remanent magnetism holding the valve slider in the obtained end position. The valve bore within the valve housing and the valve slider are each provided with a hard surface coating of titanium nitrite, wolfram carbide, or similar. The length of the valve housing may be less than 2.5 times the outer diameter of the valve slider.</p> |
