| Working Principle: | |
| 1. Open state: When the valve is in the open state, the valve handle or electric device rotates or rises the valve stem to lift the gate into the valve body. At this time, the gate is aligned with the channel in the valve body and the fluid can pass freely. The lifting height of the gate can be adjusted as needed to control the flow. | |
| 2. Closed state: When the valve needs to be closed, the stem is rotated or lowered so that the gate is lowered onto the valve seat. A tight seal is formed between the gate plate and the valve seat, blocking the flow of fluid. | |
| The gate valve is operated by the lifting and lowering motion of the gate plate to open and close. The gate provides a completely open or completely closed passage, so the flow resistance during the switching process is smaller and the pressure loss of the fluid is smaller. At the same time, the gate valve has a simple structure and high reliability, and is suitable for larger flow control and cut-off work. |
