J41W stainless steel globe valve

One. Products and Features

1. The structure of stainless steel globe valve is simpler than gate valve, and it is more convenient to manufacture and maintain.

2. The sealing surface is not easy to wear and scratch, and the sealing performance is good. There is no relative sliding between the valve disc and the valve body sealing surface when opening and closing, so the wear and scratches are not serious, the sealing performance is good, and the service life is long.

3. When opening and closing, the disc stroke is small, so the height of the stop valve is smaller than that of the gate valve, but the structure length is longer than that of the gate valve.

4. The opening and closing moment is large, the opening and closing is more laborious, and the headmaster during the opening and closing time.

5. The fluid resistance is large, because the medium channel in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.

6. Medium flow direction: When the nominal pressure PN≤16MPa, the downstream flow is generally adopted, and the medium flows upward from below the valve flap; when the nominal pressure PN≥20MPa, the reverse flow is generally adopted, and the medium flows downward from the top of the valve flap. In order to increase the seal performance. When in use, the stop valve medium can only flow in one direction, and cannot change the direction of flow.
