Is it really safe because it has a double valve? It is safer than a single valve, but a double valve only has two valve bodies inside.
Scene content: Inside the double valve, two valve bodies repeatedly open and close almost simultaneously. When one side does not close (failure) after the valve is turned off, the valve body on the functioning side closes, and the secondary side air is exhausted, causing the press to stop. However, the double valve can still operate if power is restored even when one side is malfunctioning. Air leakage occurs from the valve's exhaust port, but this "failure indication" is difficult to notice.

basic information
Points on Labor Safety/Machine Safety It cannot be said that "it is safe because it has a double valve." Continuing operations with one side malfunctioning is the same as operating with a single valve, which increases the risk of "pinch accidents."

Is it really safe because it's a double valve? It is safer than a single valve, but a double valve only has two valve bodies inside. If one valve fails, it will still operate when power is restored. (The press will continue to operate.) Scene content: Inside the double valve, the two valve bodies repeatedly open and close almost simultaneously. When power is turned off and one side does not close (failure), the valve body on the functioning side will close, allowing the secondary side air to be exhausted, thus stopping the press. However, even if one side of the double valve is in a failed state, it will still operate when power is restored. Air leakage occurs from the valve's exhaust port, but this "failure indication" is difficult to notice. Points on labor safety/machine safety: It cannot be said that "it is safe because it is a double valve." Continuing operations with one side failed increases the risk of "pinch accidents," just like operating with a single valve.
