|3/4/5 Port Solenoid Valves

Why is air constantly leaking from the EA port of my SY5120-1G-C6 solenoid valve? It has been used for cylinder driving for about five years.

Supposing the valve is not defective, air may have entered port B of the solenoid valve and collected around the valve due to internal cylinder leakage. Confirm whether the leakage is due to improper sealing of the cylinder piston seal.
