What are the Benefits of metal seated ball valves?
Under high temperature and high pressure conditions, metal-sealed ball valves can successfully replace gate valves and globe valves. Its inherent technical characteristics can be classified as:
①The medium is self-sealing, which is different from the external force seal of the globe valve and gate valve, and the external force seal may be loosened;
②In the open and closed state, the sealing surface is protected from the erosion and wear of the medium, which is different from the erosion and abrasion of the sealing surface of gate valves and globe valves under working conditions;
③90°rotation, while the gate valve and stop valve are multi-rotation, 90°rotation is beneficial to the journal packing work, and the non-lifting design can obtain a longer service life of the packing;
④Under working conditions, there is no volume change of the fluid, and the flow resistance is the smallest.
