Please help me analyze it

The picture shows the pneumatic head of the gate valve. The valve stem is currently bent. Please analyze why it is bent. It is currently known that when the valve was closed at that time, the valve position was closed to 30%, and ice should have formed in the valve, causing the valve to not close.
The valve plate of the gate valve is stuck, and the valve stem is bent and deformed due to forced closing. I have encountered this situation:(

I understand this. What I want to ask is why it is so curved.
You know the reason for the bend, but what you want to know is, why do you bend to the right and not to the left or backward or forward? Is it right?
If the gate is closed too hard, the gate is stuck, and the pneumatic head (electric head) is still moving and continues to close, eventually causing damage to the weakest link.
