709 SERIES MIXING DIVERTING VALVE

Fractional Flow Control Valve in Three Way Control Design

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.

Features & Benefits:

• 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)

Technical Specifications:

• Seat Type: Globe – Class IV or VI
• Sizes: 1/2? (DN15) and 3/4" (DN20)
• End Connections: Threaded, Autoclave, Socket Weld, Integral Tube, Welded Flange

• 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 positioner

Applications & Industries:

• Mixing, Bypass and Dosing
• Chemical injection
• Pilot plants
• Research labs
• Aviation and aerospace
• Chemical, refining and petrochemical
• Oil and gas
• Process or industrial
• Test equipment and service

LowFlow control valves and regulators are often used in OEM, laboratory or pilot plant applications for critical control of gases, liquids or steam. Installations such as these frequently require valve trim changes and a multitude of CVs in order to meet varying flow requirements for a given application.
