MV7-C THROUGH-CONDUIT GATE VALVES API6D
MV7-C THROUGH-CONDUIT GATE VALVES API6D
CAST BODY
  • This body construction is selected for high pressure designs CL. 900-1500-2500; typical services and applications would be for low or high temperature and subsea. Usually, this body design is specified by the customer in their specifications as their design preference.
  • Full in-line maintenance; the bolted top-entry construction allows disassembly on site for inspections and repairs or replacement of internal parts.
  • The flat sealing surfaces between the slab and the seats guarantee a more reliable bubble-tight shut-off for both soft and metal seats ensuring a longer life cycle in service.
  • Designed and manufactured to withstand external loads from the pipeline to prevent any deformation of the body when the internal parts are fully removed for repairs and new parts are installed.
  • Can be welded directly into the pipeline
  • Suitable for all industries and applications as shown below.
