Pneumatic cut-off ball valve

2017-03-04 View Original

Thread Content

Why does the pneumatic cut-off ball valve open slowly, while it closes normally despite sufficient air pressure?

Are there control valves on the gas line? What controls the opening speed of the valve?

What kind of valve is a solenoid valve? Two-cylinder or single-cylinder.

The pneumatic cut-off ball valve is controlled by a gas source; when there is sufficient gas supply, check the actuator. Is it possible that the setting of control parameters in the actuator is too slow or delayed? You can contact the manufacturer to have it checked.

The original poster’s question is a bit vague – is the cylinder double-acting or single-acting? Open air or closed air? If it operates in single-action mode and the air pressure is sufficient, it might be that the air supply pipe is too thin, resulting in insufficient air supply and thus slow operation

When it opens, there is a pressure difference across the valve, and it must also overcome the force of the cylinder spring, so it moves slowly. To address this issue, it is recommended to try increasing the pressure of the air tube or air supply.

Due to insufficient starting torque, the cylinder experiences crawling; increase the starting torque of the aerodynamic head

Whether it’s in open or closed position may be due to the too low torque selected for the actuator
