The Mark 708SH 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 processes such as dosing, injection and venting applications. The Short Pattern, 1/4" offers Cv's ranging from 0.00001 through 0.2 (0,000009 to 0,17 Kv in DN8). A small package ideal for critical fractional flow applications where space is at a premium.
  • The rolling diaphragm design ensures that the effective diaphragm area remains relatively constant, regardless of valve stem position

  • The spring-loaded packing maintains a proper compression, while minimizing excessive friction. This alleviates the need for most field adjusting

  • The bolting provides solid construction and secure connection

  • This bolting adds ease to maintenance, as bonnet/actuator assembly may be removed from the valve body in-line.

  • The TFE packing is suitable for temperatures to 450°F (232°C), while braided or Graphite/Grafoil may be used for higher temperature requirements.
