Description

single-seat control valve adopts the fluid pressure unbalanced plug structure. The combination of the unique single-seat plug and cage top-guided trim structure enables it to have dynamic stability of the cage control valve in addition to the advantages of the single-seat control valve, so that the repetitive positioning precision of the trim is enhanced and seat sealing tightness is ensured. The quick disassembly type trim structure makes it convenient to upgrade the trim. It is suitable for various media such as liquids, gases, pulps, polymers, high temperature media, etc. in control and shut-off applications.
