Stainless steel globe valve is a kind of stop valve, the valve body material requirements generally have higher 301.304.316 wait for a few materials are widely used in the chemical industry, Marine, pharmaceutical, food machinery and other industries. Stainless steel valve can be divided into manual stainless steel globe valve, pneumatic valve, stainless steel electric stainless steel globe valve.

Stainless steel globe valves:

(1) the structure is simpler than the gate valve, and the manufacturing and maintenance are convenient.

(2) the sealing surface is not easy to wear and abrasion, good sealing, open/close when there is no relative sliding between the disc and body sealing surface, thus wear and scratches are not serious, good sealing performance, long service life.

(3) when the valve is closed, the disc is small, so the stop valve is smaller than the gate valve, but the structure length is longer than the gate valve.

(4) the head of the opening and closing time is much more difficult.

(5) the fluid resistance is large, because the medium passage in the valve body is more tortuous, the fluid resistance is large and the power consumption is large.

(6) the flow direction of the medium is said to be less than 16 mpa. When it is said that the pressure of PN is greater than 20MPa, it is generally applied to reverse flow, which flows down the valve flap. When used, the stop valve can only flow in one direction and cannot change the direction of flow.

(7) the disc is frequently eroded by the open.
