The inlet hole of the 22FDA-F5T-W220R-20/LBO test solenoid valve is normally open, and hydraulic oil enters different oil discharge pipes. Then, the pressure of the oil pushes the piston of the oil cylinder, which drives the piston rod, which drives the mechanical device.

The solenoid valve 22FDA-F5T-W220R-20/LP is used for the steam turbine safety system. During normal operation, the solenoid valve is powered off, allowing high-pressure oil to directly flow to the upper chamber of the unloading (DUMP) valve. When the solenoid valve is energized, it opens the return oil channel and cuts off the high-pressure oil supply.

The 22FDA-F5T-W220R-20/LBO test solenoid valve has voltages of 220V, 110V, and 24VAC to choose from. The coil is not separately matched, and the coil+valve body+installation fixing screws are a set.

The solenoid valve 22FDA-F5T-W220R-20/LP is a conical valve type plug-in electromagnetic directional valve that plays a role in on-off, pressure maintaining, and unloading. The solenoid valve has the advantages of compact structure, large flow rate, small pressure loss, no leakage, and fast directional speed. Can ensure the good operation of the equipment.

Except the test solenoid valve, the steam turbines in thermal power plants use various types of valves, such as:
