Product Description

intro

The stem opening or closing stroke is relatively short, and the J41W globe valve has very reliable features
The cutting action of the J41W makes this valve very suitable for use as a medium to cut off or adjust and throttle. J41W series stainless steel globe valve once in the open state, its seat and valve disc sealing surface is no longer in contact with each other, so its sealing surface mechanical wear is small, because most of the globe valve seat and valve disc is easier to repair or replace the sealing element without removing the whole valve from the pipeline, which is very suitable for the valve and pipeline welded into one. The flow direction of the medium through this kind of valve has changed, so the flow resistance of the globe valve is higher than other valves.

Product holding point

1, stainless steel globe valve structure is simpler than gate valve, manufacturing and maintenance are more convenient.
2, the sealing surface is not easy to wear and abrasion, good sealing, there is no relative sliding between the valve disc and the valve body sealing surface when opening and closing, so the wear and abrasion are not serious, good sealing performance, long service life.
3. When opening and closing, the valve flap stroke is small, so the height of the globe valve is smaller than the gate valve, but the structure length is longer than the gate valve.
4, the opening and closing torque is large, the opening and closing is more laborious, and the opening and closing time is the principal.
5, the fluid resistance is large, because the medium channel in the valve body is more tortuous, the fluid resistance is large, and the power consumption is large.
6, the medium flow direction: nominal pressure PN≤16MPa, the general use of downflow, the medium from the direction of the valve disc upstream; Nominal pressure PN≥20MPa, the general use of countercurrent, the medium from the direction of the valve disc downstream. To increase the sealing energy. When used, the globe valve medium can only flow in a single direction and cannot change the direction of flow.
7, J41W stop valve fully open valve disc is often eroded.

Application specification

1, design and manufacture according to GB12235-89
2, the structure length according to GB12221-89
3, flange size according to JB/G79-94
4, valve inspection and test according to GB13927
