The Mark 708 was developed to provide the most accurate control available for fractional flow services; whether for pilot plant installations, test stands, R & D facilities, or for specialized usage in processes such as dosing, injection and venting applications. With Cv's ranging from 0.00001 to 4.0 available in the 1/4" through 3/4" line sizes (0,000009 to 3,4 Kv in sizes DN8 through DN20), the Mark 708 offers design features that will provide enhanced performance to insure precision control on your most critical micro-flow flow applications.
