Mark708 MAX Series

Brand: LowFlow Valve
Does not ship to VA, United States
The Mark 708 MAX product is a Diaphragm Operated Control Valve with a maximum flow coefficient of 10Cv from a 0.875 in diaphragm orifice. 

There are two Cv’s covered: 6.5 and 10. Class IV hard seats and Class VI soft seat with PEEK. Standard actuator is the 35M, with 3-15 and 6-30 bench sets, available for ATC / ATO. 

All positioners normally offered on the ¾” Mk708 are available on the Mk708 MAX. Optional end connection can be added as needed: BSPT, BSPP, and Welded Flanged Ends.
Features
  • Rolling diaphragm design ensures that the effective diaphragm area remains relatively constant, regardless of valve stem position
  • Spring-loaded TFE-Chevron packing maintains a proper compression while minimizing excessive friction
  • Bolted body/bonnet connection
  • Guide trim – extended orifice and plug guiding are standard and offers improved shutoff and accuracy equivalent to heavy duty trim options of competitors
  • Quick change trim
