Bellows Seal Globe Valve is a general-purpose valve used to cut off and control the flow and is one of the commonly used valves at home and abroad. Due to the formation of a certain gap between the stem and the valve seat, the medium through the valve, by its own force and the role of external power produces a certain rotation of the stem, thereby changing the flow direction of the medium through the valve, improving the flow characteristics. For high-pressure requirements, high flow and the need to adjust the medium temperature or pressure conditions change is very suitable for the occasion.

l Convenient for later maintenance
l No Leakage
When the medium flow rate is large, the ball seal is generally used. In order to ensure that the sealing surface is not subject to wear, it is necessary to strengthen the seal, so that the valve has a good seal. Bellows Seal Globe Valve compared with the gate stop valve, because the inner cavity of the sealing surface is conical, so the work can reduce the valve flap by the fluid flush open and cause damage.
With the improvement of the domestic production process, most chemical enterprises have been able to produce corrosion-resistant, high temperature resistant stainless steel globe valve. Stainless steel Bellows Seal Globe Valve adopts a more advanced production process and design theory, which can achieve the characteristics of valve heat resistance, corrosion resistance, high valve precision, and high operating pressure.
When working, the valve stem does not produce rotation and the valve flap closes quickly, so the opening and closing force is small. The valve flap has a very good streamlined structure with good elasticity and compensation ability. The flow channel structure is reasonable, which can effectively prevent fluid backflow and produce accidents or improve the use performance of the system. It has the advantages of small leakage, long life, reliable sealing, etc. It is safe and reliable to use. This is one of the biggest advantages of Bellows Seal Globe Valve, which can greatly reduce the cost of later maintenance.
Bellows Seal Globe Valve is usually used in the bend of the pipeline, its role is to cut off the media in the pipeline. The valve body is equipped with a guide ring, which allows the valve stem to be redirected through the guide ring. Bellows Seal Globe Valve should also be designed with different structural forms according to the medium, such as sleeve structure and bellows structure. However, due to the different materials and process requirements of the valve seat, the manufacturing cost and usage cost will also be different and make the valve design more difficult.
The above is our introduction to several applications of Bellows Seal Globe Valve, hope to provide you with help. Our introduction is not very comprehensive, but we hope it can be helpful to you.
