    Welding stop valve STY15

    The straight-through globe valve relies on the stem pressure to tightly bond the disc sealing surface to the seat sealing surface to prevent media flow. In the process of opening and closing, the friction between the sealing surfaces is small, wear-resistant, the opening height is small, and the manufacturing process performance is good. It is the most widely used valve in the industrial sector. Compared with the gate valve, the structure of the shut-off valve is relatively simple, and the manufacturing and maintenance are relatively convenient; the sealing surface is not easy to wear, scratch, seal, and has a long service life; the valve stroke is small when opening and closing, and the opening and closing time is short.
