Brake handle as a valve control device, mainly assume the following roles:

Control the flow of the medium: The brake handle regulates the flow of the medium by controlling the position of the gate valve. When the brake handle is opened, the gate rises and the medium can pass smoothly through the valve; When the brake is closed, the ram descends, stopping the flow of the medium.

Adjusting the opening of the valve: The brake handle usually has a mark and scale to show the position and opening of the ram. By rotating or pushing the brake handle, the position of the ram can be fine-adjusted to control the opening of the valve. Different openings correspond to different flows or pressures.

To realize the switch of the valve: the gate itself has a switch function, which can open or close the valve. When the brake handle is in the closed position, the valve is completely closed, blocking the flow of the medium; When the brake handle is in the open position, the valve is fully open, allowing the medium to flow.

Provide ease of operation: The design and operation of the brake handle are usually simple and easy to operate. It can be controlled by rotating, pushing and pulling, and the user can easily adjust the opening and closing state of the valve.

In summary, the function of the brake handle is to control the flow rate of the medium and the opening of the valve, to achieve the on-off operation of the valve, and to provide a convenient mode of operation. It plays an important function in the valve system in various fields to ensure the normal operation of the fluid system.
