- Bolted Bonnet Globe Valve
- Pressure Seal Globe Valve
Globe Valve is a force seal valve, being widely used in nuclear power plants and petrochemical power plants, so pressure must be applied to the disc to prevent the sealing surface leakage when closing the valve.
For high temperature, high pressure and other harsh working conditions, our company has developed a new type of pressure seal globe valve: the higher the medium pressure, the better the sealing performance. In this new valve, the specific pressure between the packing box and the pressure seal gasket, as well as between the valve body and the pressure seal gasket, increases gradually with the increase of pressure by adjusting the structure design of the holdback bolt and floating packing box, so the sealing performance of the valve is better.
