Hebei Qianfeng Metallurgical Technology Co., Ltd.  

Product Name: Welded Ball Valve Model NO.: Q61H-16C Application: Industrial Usage, Water Industrial Usage, Household Usage Temperature: Normal Temperature Function: Blow-Down Valve, Relief Valve, Atmospheric Valve Type: Floating Ball Valve Structure: Floating Ball Valve Channel: Straight Through Type Nominal Pressure: PN1.0-32.0MPa Connection Form: Welding Material: Stainless Steel Media: Oil Trademark: Qiangongfeng Transport Package: Wooden Box Origin: Hebei HS Code: 848120200 Product Description 1. Welded ball valve body structure integral welding, there will be no external leakage.2. The valve seat is composed of PTFE sealing ring and spring, which has strong adaptability to the change of pressure and temperature, and will not produce any leakage in use.3. The leak-proof structure of the stem, there is a PTFE self-sealing gasket and an O-ring at the bottom of the stem. There are two O-rings and two PTFE gaskets on the top to ensure no leakage.4. The material of the valve body is the same as that of the pipeline. There will be no uneven stress and no extrusion deformation due to the earthquake or when the vehicle passes through the ground.5. The valve body is light and easy to heat preservation.6. Direct-buried ball valves can be buried directly in the ground, without building large valve wells, only small shallow wells on the ground, greatly saving 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. Machining accuracy of sphere is very precise and easy to operate without bad interference.10. There are welding and flange connection modes.11. Operation mode: handle, gear (vertical/horizontal)12. In the case of normal operation and use of valves, the warranty period is 20 years.1. The valve adopts carbon steel seamless steel pipe to press and form integral welded ball valve.2. The valve stem is made of AISI303 stainless steel and the valve body is made of AISI304 stainless steel. The valve body is made by finishing and grinding. It has excellent sealing performance and corrosion resistance.3. Carbon-reinforced PTFE inclined elastic sealing ring is used for negative pressure on the sphere to make the seal zero leakage and long service life.4. Connection mode of this valve: welding, threading, flange, etc. for users to choose. Transmission mode: handle, turbine, pneumatic, electric transmission structure, flexible and light switch.5. The valve has compact structure, light weight, easy insulation and easy installation. This valve is generally installed horizontally.6. Integral welding ball valve is developed by absorbing advanced technology from abroad and combining with the actual situation in China, replacing imports with domestic ones, filling the gap in China. It is widely used in the fields of natural gas, petroleum, heat supply, chemical industry and heat and power pipeline network
