The pressure seal globe valves are designed 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.
Globe valves is used for throttling flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction, resulting in greater resistance to flow, causing high pressure drop. Globe valve is an excellent valve to use for on-off service, also is highly suited for frequent cycling and control of fluids anywhere in amount or volume between the open and closed positions.

Main structural features：
1.This product has logical structure, reliable seal, excellent performance and nice design.
2.The seal surface is build-up welding with Co hard alloy, which is attrition-resistant, corrosion-resistant, has good friction resistant and long life.
3.It has double seal capability, thus is more reliable.
4.The stem may show the position of lift, thus it is clearer.
5.The part material, flange and butt weld end dimension may be selected according to current operating condition and users 'requirement, so that meet the requirements of various engineering.
