Features of metal sealed floating ball valve
1. The sealing surfaces of the ball and the valve seat are sprayed with nickel base hard alloy, carbide, nitride and other hard surface materials, which increase the wear resistance, scratch resistance and erosion resistance of the sealing surface in the working conditions with particles, high temperature and high pressure.
2. The spring loaded valve seat makes the valve seal stable and reliable.
3. Metal sealed ball and valve seat make the valve have intrinsic fire protection function.
4. Anti fly out valve stem design.
5. Class A or B low leakage packing can be used to meet the requirements of low leakage sealing (FE) of the valve.
6. The valve stem is made of high hardness and high strength materials, which improves the wear resistance and scratch resistance of the valve stem, enabling the valve to open and close in place and operate stably.
7. It is equipped with ISO 5211 standard connection panel, which can be used to install pneumatic device, electric device, pneumatic hydraulic linkage and other remote control mechanisms for automatic control system.
Characteristics of metal sealed fixed ball valve
1. The sealing surfaces of the ball and the valve seat are sprayed with nickel based cemented carbide, tungsten carbide, chromium carbide, and coated with hard surface materials such as chromium nitride. In the working conditions with particles, high temperature, and high pressure, the wear resistance, scratch resistance, and erosion resistance of the sealing surfaces are increased.
2. The spring loads the valve seat, and the spring is equipped with an anti particle device to prevent particles from blocking the spring hole, so that the valve can operate stably and reliably.
3. The valve seat is a scraper structure, which can automatically scrape off the viscous attachments attached to the surface of the ball during the valve opening and closing process.
4. The ball and valve seat adopt 360 degree dead angle grinding method, with the surface reaching the mirror surface of Ra0.2, reducing the torque of the valve and improving the service life of the ball and valve seat.
5. The ball and valve seat of metal seal enable the valve to have fire protection function.
6. Anti fly out valve rod design.
7. Low leakage packing Grade A or B can be used to meet the requirements of low leakage seal (FE) of valve ISO 15848 standard.
8. The valve stem is made of high hardness and high strength materials, which improves the wear resistance and scratch resistance of the valve stem, so that the valve can still be opened and closed in place after long-term use, and the operation is stable.
9. Three hardening bearing structure, low valve opening and closing torque.
10. It is equipped with ISO 5211 standard connecting plate, which can be used to install pneumatic device, electric device, pneumatic hydraulic linkage and other remote control mechanisms for automatic control system.
