What is the function of the (air) buffer valve of the cylinder?

Create Date: 2024-8-30 12:03:23|Source: SMC

A buffer valve is a valve that adjusts the release flow of the enclosed gas when absorbing the kinetic energy generated at the end of the stroke.

Before the end of the stroke, the contact between the buffer sleeve and the buffer seal causes the exhaust to be sealed, the pressure rises, and the shock is absorbed.

The compressed air on the exhaust side where the pressure rises is exhausted through the orifice installed on the end cap, and the cylinder operates at full stroke.

The adjustment method is as follows: For safety reasons, please start from the fully closed state of the buffer valve and slowly relax to adjust.

(The air cushion belt of the RQ and CXS is a separate structure without a buffer sleeve.)

2. Can the cylinders of this (or more) be operated at the same time? —SMC 2. Can the cylinders of this (or more) be operated at the same time? —SMC

It is difficult to control two (or more) cylinders at the same time with one valve. The reason for this is that even if the piping conditions are the same, the friction of each cylinder seal and the friction of the guide rod are different, so it is not possible to operate synchronously. Even if piping conditions and load are equal, speed regulation is adjusted, etc.

SMC FAQ - Why does the 5-port solenoid valve operate poorly at low pressure (0.1MPa)? SMC FAQ - Why does the 5-port solenoid valve operate poorly at low pressure (0.1MPa)?

The internal pilot operated solenoid valve uses the pilot pressure to switch the spool and change (control) the flow path. If the pilot pressure does not reach the minimum operating pressure of the switching spool (0.1-0.2MPa: varies depending on the model), the switching will be defective. If you want to use a 5-way solenoid valve at low pressure, you can use ...
