What are Pressure Seal Globe Valves
The pressure seal globe valve is designed according to the standard bs1873 and ASME B16.34. This valve is mainly used in fossil fuel power plants under high temperature and high pressure. Compared with the bolted valve, this valve provides an absolute safety seal at the valve cover connection. Therefore, the pressure seal globe valve can provide closer service for valve maintenance under high temperature and high pressure environment.
This is a double open valve with medium flow. The inlet and outlet form an angle of 180 degrees. In addition, for the long-term service of the valve, cast iron alloy, cobalt alloy or carbide alloy shall be overlaid on the sealing surface of the valve seat and valve plate. The large-diameter valve will be designed to be composed of main valve plate and auxiliary valve plate. The medium flows from the upper valve plate to the lower valve plate, The operating torque is greatly reduced and the sealing performance of the valve seat is more prominent.
We focus on valves in standard and special materials as customer request.
