WJ44H Bellow seal angle globe valve Product introduction

　WJ44H Bellow seal angle globe valve is bellow seal for better seal performance, WJ44H Bellow seal angle globe valve is a modified globe valve whose inlet and outlet are at right angles to each other. The basic design of WJ44H Bellow seal angle globe valve is the same as a globe valve, but they have a fundamental difference in the direction of fluid flow as in the angle valve, the fluid makes a 90° turn. Bellow seal angle globe valve is used in lines where the pipe construction or pressure drop is complex. Depending on the line pressure, bellow seal angle globe valveis available with pressure-seal or bolted bonnets.

WJ44H Bellow seal angle globe valve is a forced sealing valve, so when angle globe stop valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters WJ44H Bellow seal angle globe valvecavity from below the disc, the resistance to be overcome by the operation force is the friction force of the stem and the filler and the thrust generated by the pressure of the medium. The force of closing the valve is greater than the force of opening the bellow seal angle globe valve, so the diameter of the valve stem should be large, otherwise the failure of the top bend of the valve stem will occur. In recent years, from the emergence of the self-sealing valve, the medium flow direction of the stop valve is changed from the top of the valve disc into the angle globe stop valve cavity. At this time, under the action of medium pressure, the force of closing angle globe stop valve is small, and the force of opening the valve is large, and the diameter of the stem can be reduced accordingly. At the same time, under the action of the medium, this form of valve is also more tight.

WJ44H Bellow seal angle globe valve application:

WJ44H Bellow seal angle globe valve applications can be commonly identified in industries like shipbuilding, petrochemicals, pharmaceuticals, aerospace, etc.

1. WJ44H Bellow seal angle globe valve is used to control medium flow in cooling water systems, fuel oil systems, etc.

2. WJ44H Bellow seal angle globe valve is also used for feedwater, chemical, air, lube oil, and similar services where pressure drop is not a concern.

3. They are deemed most appropriate for applications where leakage and safety are significant concerns, such as high point vents and low point drains.

4. Due to their design, WJ44H Bellow seal angle globe valve is widely used in the control circuits to control a wide range of flow and pressure drop.

5. The durability to sustain an extensive range of temperatures and pressures enables WJ44H Bellow seal angle globe valve can be used in a high-pressure environment such as steam, hydraulics, etc.
