The Mark 709 is a lightweight control valve for use as a mixing valve in low flow process applications. Featuring a three-way body design, it is constructed with two inlets to blend two separate flow streams into a common outlet, creating a third fluid.
  • For low flow process applications requiring a three way body for mixing two separate flow sources into one common line

  • Compact, lightweight design for precise control

  • Multiple spring actuators in a choice of sizes for differential pressures up to 1460 psi (100 bar)

  • Cv (Kv): 1.25 to 4.0 (1,1 to 3,4)

  • Ranges: 3-15 or 6-30 psi; split ranges are available with optional top-mounted positioner
