Q347F-16C Ash Unloading Flange Hard Sealed Fixed Ball Valve

Product Overview

The Q347F-16C Ash Unloading Flange Hard Sealed Fixed Ball Valve is mainly used for cutting off or connecting media, and can also be used for fluid regulation and control. By selecting different materials, it can be applied to various media such as water, steam, oil products, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing media, urea, etc.
1. Low fluid resistance, ball valve is one of the valves with low fluid resistance, even for reduced diameter ball valves, its fluid resistance is quite small
2. The switch is fast and convenient. As long as the valve stem rotates 90 °, the ball valve completes the fully open or fully closed action, making it easy to achieve rapid opening and closing
3. Good sealing performance. The sealing ring of the ball valve seat is generally made of elastic materials such as polytetrafluoroethylene
4. The valve stem seal is reliable. When the ball valve is opened and closed, the valve stem only rotates, so the packing seal of the valve stem is not easily damaged, and the sealing force of the valve stem reverse seal increases with the increase of medium pressure
5. The opening and closing of the ball valve can only rotate 90 degrees, making it easy to achieve automation and remote control. The ball valve can be equipped with pneumatic devices, electric devices, hydraulic devices, gas-liquid linkage devices, or electro-hydraulic linkage devices
6. The ball valve channel is flat and smooth, not easy to deposit media, and can be used for pipeline ball passing

Performance Characteristics

• The long neck valve cover structure isolates the packing box from the low-temperature position, ensuring the sealing effect of the packing and making it easier to wrap the insulation material. It has the function of protecting the packing box and preventing the loss of cold energy of the low-temperature valve.
• The gasket used for low-temperature ball valves has reliable sealing and recovery properties at room temperature, low temperature state, and temperature changes.
• When the operating temperature is below -100 ℃, the valve stem material is treated with chrome plating or nitriding to increase the surface hardness of the valve stem and improve the reliability of the packing seal.
• The low-temperature ball valve is designed with a structure to prevent abnormal pressure rise. A pressure relief valve is installed at the inlet end of the valve, which can effectively prevent the pressure in the valve chamber from rising and ensure the safe use of the valve.
• When used in working conditions below -100 ℃, valve parts should undergo cryogenic treatment before precision machining, which involves immersing the parts in a liquid nitrogen tank for cooling.
