High Pressure Seal Globe Valve

High Pressure Seal Globe Valve

Categories:High Pressure Seal Globe Valve

Brief Introduction


FYV high pressure seal globe valve’s top and bottom-guided disc assures stem ?operation without side thrust caused by high pressure flow. The non-rotating stem results in lower friction of all moving parts and longer stem packing life. All this resulting in smooth, easy operation and tight shutoff under extreme pressures.

The high pressure seal valves are designed in accordance with BS1873 and ASME B16.34 for service of high temperature and high pressure and are widely used in fossil fuel power plant. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service.
