Our Pressure Seal Globe Valves are ideal for high pressure steam, liquid, catalytic reformers, hydrocrackers and other tough services. In the tough world of High pressure, High temperature valve applications, Pressure seal Globe Valve continue to provide a wide range of industries with a safe, leak free, pressure containing boundary. These valves are best suited for throttling application at high pressure and temperature.
The pressure seal globe 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.
Design standard as per: BS1873,ASME B16.34, GB/T 12235, JB/T3595.
Generally, lift is just 1/4 of the valve seat port, ensuring a short opening and closing time.
Only one sealing face is designed on the valve body and valve disc,
For large size valves will be designed with main disc and vice disc type, and medium flow from up disc to down disc.
