Valved cylinder refers to a device equipped with an electromagnetic electronically controlled reversing valve. The cylinder mechanism is simplified, easy to use, and highly automated. It is widely used in environmentally friendly dust removal equipment. Cylinders with valves can have a controlled function, including piston cylinders, which are characterized in that: the piston cylinder is equipped with a two-position five-way distribution valve, a two-position three-way distribution valve and an air storage tank. The two-position five-way distribution valve has five channels. The two ports of the piston cylinder are connected to the two air inlets of the piston cylinder, the air source, the first port of the two-position three-way distribution valve and the gas storage tank. The other two ports of the two-position three-way distribution valve are connected to the gas storage tank and the atmosphere respectively. The first control chamber of the main valve of the five-position distribution valve is connected with the first control chamber of the main valve of the two-position three-way distribution valve, and the other control chamber of the main valve of the two-position three-way distribution valve is connected with the gas storage tank.
