Main features

The J11W internal thread shut-off valve is a forced-sealed valve, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface to not leak. After the appearance of the self-sealing valve, the internal flow of the internal thread and the flange stop valve is changed from the valve flap to the valve chamber. Under the action of the medium pressure, the force of closing the valve is small, and the force of opening the valve is large, the valve The diameter of the rod can be correspondingly reduced. At the same time, this type of valve is also tight under the action of the medium.

Design Features

1. Simple structure, convenient manufacturing and maintenance.

2. The working stroke is small and the opening and closing time is short.

3. good sealing, small friction between sealing surfaces, long life.
