The internal structure and principle of the pilot-operated check valve, Air cut-off protection to prevent the cylinder from falling
The principle of the pilot operated check valve is similar to that of the pressure holding valve, the exhaust port also needs to be vented before it can be opened, and if the air is cut off, the exhaust port will automatically close to prevent the cylinder from falling.
With the internal structure and principle of the pilot operated check valve, the air is cut off to prevent the cylinder from falling
How to use pilot operated check valve:
Internal structure and principle of pilot operated check valve:
The No.12 in the picture below is the pilot hole port, which is connected to the upper end of the cylinder (see the picture above, the pilot operated check valve is installed at the interface at the lower end of the cylinder), if you want to lower the cylinder rod. In addition to venting the top port, the pilot operated check valve is also vented, opening the drain channel for smooth exhaust.
