  • Size range: 1/2" to 2", full port.
  • Pressure rating: 1000 psi WOG (69 bar).

The Marwin 8700F is a great choice for industrial isolation duties where users want a compact full port ball valve with actuator-ready mounting and the serviceability benefits of a three-piece design. It is especially well suited to packaged systems, OEM equipment, utility/process lines, and applications where future maintenance access matters.

Applications

Common process applications and industrial uses include:

  • Manual or automated on/off isolation duties in general industrial process lines.
  • Skid systems and packaged equipment where an ISO 5211 mounting pad and automation-ready options are useful.
  • Systems where a 3-piece valve is preferred because seats, seals, and packing may need servicing.
  • Threaded or socket weld installations using carbon steel or stainless steel valve bodies.
  • Applications needing manual lever operation or packaged pneumatic/electric actuation.
