Q341F flange fully welded ball valve product overview:
Q341F flange fully welded ball valve is widely used in various fields. The flange fully welded ball valve is unattainable by ordinary cast steel ball valves due to its superior quality and high performance stability. The service life of flange fully welded ball valve is much longer than that of cast steel ball valve. It is widely used in various pipeline equipment such as urban gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating station, power plant, etc. Fully welded ball valves can be buried directly underground, without building tall valve wells to reduce project costs, and can also avoid injuries to personnel when operating valves. Fully welded ball valves can be used reliably for a long time.
Q341F flange fully welded ball valve uses:
1. Urban gas: gas output pipelines, trunk lines and branch supply pipelines, etc.
2. Central heating: large-scale heating equipment output pipelines, trunk lines, and branch lines.
3. Heat exchanger: pipeline and each circuit opening and closing.
4. Iron and steel mills: various fluid pipelines, exhaust gas emission pipelines, gas and heat supply pipelines, fuel supply pipelines.
5. Various industrial equipment: various heat treatment pipelines, various industrial gas and heat pipelines.
Q341F flange fully welded ball valve structural features:
1. The valve body structure is integrally welded, and there will be no external leakage.
2. The valve seat is composed of PTFE sealing rings and springs, which have strong adaptability to changes in pressure and temperature and will not cause any leakage within the range of use.
3. The anti-leakage structure of the valve stem, there is a PTFE self-sealing gasket and an O-ring at the bottom of the valve stem, and there are 2 O-rings on the top, composed of two PTFE gaskets, to ensure no leakage.
4. The valve body material is the same as the pipeline material, there will be no uneven stress, and it will not be squeezed and deformed due to earthquakes and vehicles passing through the ground.
5. The valve body is light and easy to keep warm.
6. Direct buried ball valves can be buried directly underground. There is no need to build tall valve wells. Only small shallow wells need to be set up on the ground, which greatly saves construction costs and engineering time.
7. The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline.
8. The processing accuracy of the ball is very accurate, the operation is easy, and there is no adverse interference.
10. There are two connection methods: welding and flange.
11. Operation method: handle, gear (vertical/horizontal)
