      Application

      B41HT piston solenoid valve is widely used in military and aerospace industry. Shipbuilding industry, nuclear industry, petrochemical industry,electric power, chemistry, light industry, machinery, scientific research,drying equipment, food, medical treatment, cleaning equipment,automatic control of pipeline media and other fields.

      Features

      Precision casting, patented technology, unique design; Thestructure and performance of the piston are stable. Specialmaterials, good sealing; Autocratic coil, not easy to burn.Lownegative pressure vacuum can be realized.

      Principle

      Normally closed: when energized, the solenoid valve wicks in, thepressure relief hole opens, and the main piston is pushed upwardto open the main valve port and the medium circulates. After thepower is cut off, the main valve port is closed and the medium is cutoff.Normally open: when energized, the solenoid valve wicks in andthe pressure relief hole closes, and the main piston is pushed bythe medium pressure to close the main valve port and the mediumcloses.
