Product Description

The reversing valve is a directional control valve with more than two flow forms and more than two oil ports. It is a valve that realizes the communication, cutting off and reversing of hydraulic oil flow, as well as pressure unloading and sequential action control. It can be divided into manual reversing valve, electromagnetic reversing valve, electro-hydraulic reversing valve and so on. Also known as Chris valve, a kind of valve, with a multi-directional adjustable channel, can timely change the flow of fluid. When working, the drive transmission mechanism outside the valve rotates the drive shaft, with a shaking arm, and starts the valve plate, so that the working fluid sometimes leads from the left entrance to the lower exit of the valve, and sometimes from the right entrance to the lower exit, to achieve the purpose of periodic change of flow direction. This kind of change valve has a wide range of applications in petroleum and chemical production, and is commonly used in synthetic ammonia gas making system. In addition, the reversing valve can also be made into a disc type structure, which is mostly used in the occasions of small flow. When working, just turn the hand wheel through the valve disc to change the flow of working fluid. Caliber specification: DN25-100, material: SUS 304 SUS 306L, standard: DIN ISO, link method: welding fast assembly.

The reversing valve is used to switch the material flow direction in the equipment pipeline, and is widely used in food, wine, beverage, dairy products, toothpaste, cosmetics, biopharmaceutical and other industries.

Working principle

Access 24V DC power supply, circuit board, proximity switch power, give the incoming signal to open the solenoid valve to make the air source into the cylinder. The compressed air is used to push the piston in the pneumatic actuator up, and the piston rod and valve stem are connected with the positioning card. At the same time, the air compression is used to push the piston in the pneumatic actuator up, and the valve stem is also pulled up, so that the sealing surface of the valve seat compresses the sealing plane of the upper valve body, that is, the upper valve port is connected. When the air compression is lower than the spring force or no gas compression, the piston under the action of the spring, the piston pushes down and drives the valve stem down to close the lower valve port. It is mainly used for fluid switching in the pipeline system, one way into two ways out of the switch, applied to the pipeline system without pollution or mixing.
