Pneumatic reversing valve is a control component in the pneumatic system. There are many styles to control the flow of fluid in the system, and users can choose according to their own needs.
Cylinder reversing valveThe common types are as follows:
According to the air outlet: two-way, three-way, four-way and five-way;
According to working position: two and three positions.
According to control mode: pneumatic control and electronic control, direct-acting and pilot-operated;
According to the controlled medium: fluid valve and gas valve;
According to function: normally closed and normally open, middle sealing and middle leakage, and middle air supply;
According to structure: there are stop valves and slide valves;
ShoppingCylinder reversing valveThe following points should be noted:
1. Threaded interface of the reversing valve: The nominal diameter of the reversing valve does not correspond to the air port thread. Therefore, attention should be paid to the interface thread when selecting the reversing valve.
2. Installation dimensions of reversing valves: reversing valves of the same model and function have different shapes and installation dimensions due to different manufacturers.
3. Whether the reversing action is crisp and clear, without any sloppiness.
4. Solenoid valves, especially AC solenoid valves, should pay attention to their insulation performance. To ensure the operator's personal safety.
5. The reversing valve should have no external leakage, and the smaller the internal leakage, the better. Otherwise, the normal operation of the system will be affected and energy will be wasted.
6. Pay attention to the factory date of the valve. If the cylinder reversing valve is left open for too long, its lubricating grease will age and affect Cylinder The normal operation of the reversing valve.
