Design NotchFlo ® DST Control Valve

NotchFlo DST Valve Description CL600 3-stage, CL900 and CL1500 4-stage, and CL2500 6-stage Design NotchFlo DST control valves (figure 1) with dirty service anti-cavitation trim (figure 2) offer excellent control of high pressure drop liquids with entrained solids while avoiding the damaging effects of cavitation and erosive solids.

Features

  • Long Trim Life—NotchFlo DST control valves feature a protected seat design whereby the shutoff function is separate from the throttling areas of the trim.
  • Class V Shutoff—Use of hardened metal seats provides tight shutoff to minimize seat erosion.
  • High Pressure Drops—Rugged cage guiding of the plug, combined with a staged pressure drop, enables the NotchFlo DST control valve to be effective in a wide range of allowable high pressure drop applications. It can be operated by either spring and diaphragm or piston actuators, depending on plug design (balanced or unbalanced) and application requirements.
  • Sour Service Capability—Materials are available for applications handling sour fluids. All references in this document are for NACE MR0175-2002 unless otherwise noted. Contact your Emerson Process ManagementTM sales office for information on NACE MR0175/ISO 15156 and NACE MR0103.
  • Availability—NotchFlo DST control valves are available in both globe and angle valve body designs.

Principle of Operation NotchFlo DST control valves utilize a high resistance, multi-stage, axial flow path (or passage) where fluid flow is parallel to the axis of the plug and cage (see figure 2).
Pressure reduction occurs throughout the length of the plug; thus individual stages aren't exposed to the full pressure differential. Therefore, trim life is enhanced.
NotchFlo DST trim utilizes a series of notched flow restrictions and expansions to control the pressure drop of the fluid. The amount of pressure drop per stage is controlled to prevent cavitation problems and minimize erosion issues on a properly sized valve.
Flow passage configuration provided by the multi-stage plug and cage design make CL600 3-stage, CL900 and CL1500 4-stage, and CL2500 6-stage valves well-suited for applications involving fluids with entrained particles. This is a potentially serious problem for other anti-cavitation valve designs which are subject to clogged flow passages.
Design of the trim allows for high rangeability.
       Close Section Above

Characteristics The NotchFlo DST control valve has a linear flow characteristic. See figure 3.
To maximize seat life, the trim is designed not to have significant flow for the first 15% of travel.
The multi-stage clearance flow design helps prevent high pressure drops in the seating area during throttling at low capacity. This design feature extends the shutoff capability significantly, while enhancing throttling control capability at low travels.

Trim Selection Guidelines Refer to the following descriptions and tables 4, 5, and 6 as guidelines for the selection of appropriate trims. Trims 278, 278N, 279, 281, 282, and 283 should not be used in boiler feedwater due to amine corrosion problems associated with CoCr-A and R30006 (alloy 6).

  • Trim 277—Trim 277 is the standard trim for carbon steel and alloy steel valve bodies and recommended for general and severe service applications up to 316°C (600°F). See tables 4 and 5 for operating temperature ranges per valve size. Typical applications for Trim 277 include services in boiler feedwater, water, non-sour hydrocarbons, and other non-sour liquids.
  • Trim 278—Trim 278 is the standard trim for stainless steel valve bodies and is optional for use in carbon steel and alloy steel valve bodies. Trim 278 is recommended for use in moderately corrosive liquid applications. Trim 278 can be used up to 316°C (600°F). See tables 4 and 5 for operating temperature ranges per valve size. Not suitable for boiler feedwater use if amine problems exist.
  • Trim 278N—Trim 278N should be used for sour liquid service in carbon steel, alloy steel, and stainless steel valve bodies. Trim 278N complies with the requirements of NACE MR0175-2002. Trim 278N can be used up to 316°C (600°F). See tables 4 and 5 for operating temperature ranges per valve size. Not suitable for boiler feedwater use if amine problems exist.
  • Trim 279—Trim 279 is available with CL600 3-stage control valves only and should be used for sour liquid service in carbon steel, alloy steel, and stainless steel valve bodies. Trim 279 complies with the requirements of NACE MR0175-2002. Trim 279 can be used up to 316°C (600°F). See table 4 for operating temperature ranges per valve size. Not suitable for boiler feedwater use if amine problems exist.
  • Trim 280—Trim 280 is available with CL1500 ≥ NPS 6 and CL2500 control valves only and should be used in SA105 steel valve bodies. Trim 280 can be used up to 316°C (600°F). See table 5 for operating temperature ranges per valve size. Typical applications for Trim 280 include services in boiler feedwater, water, non-sour hydrocarbons, and other non-sour liquids.
  • Trim 281—Trim 281 is available with CL1500 ≥ NPS 6 and CL2500 control valves only and should be used in SA105 NACE steel valve bodies. Trim 281 complies with the requirements of NACE MR0175-2002. Trim 281 can be used up to 316°C (600°F). See table 5 for operating temperature ranges per valve size. Not suitable for boiler feedwater if amine problems exist.
  • Trim 282—Trim 282 is available with CL1500 ≥ NPS 6 and CL2500 control valves only and should be used in 316 stainless steel valve bodies. Trim 282 complies with the requirements of NACE MR0175-2002. Trim 282 can be used up to 316°C (600°F). See table 5 for operating temperature ranges per valve size. Not suitable for boiler feedwater if amine problems exist.
  • Trim 283—Trim 283 is available with CL1500 ≥ NPS 6 and CL2500 control valves only and should be used in 347 stainless steel valve bodies. Trim 283 complies with the requirements of NACE MR0175-2002. Trim 283 can be used up to 316°C (600°F). See table 5 for operating temperature ranges per valve size. Not suitable for boiler feedwater if amine problems exist.

Valve Sizing Guidelines Standard ISA equations, sizing procedures from Catalog 12, or Fisher® Specification Manager can be used to size NotchFlo DST control valves.
Noise calculations are best performed by using Fisher Specification Manager. The serial stage configuration of the NotchFlo DST design reduces valve trim noise significantly. Select CAV III 2-Stage as the valve type in Fisher Specification Manager to perform the noise prediction calculation.
Selection of the correct trim can be made by determining the KC value from table 7.
Ensure that the correct KC value for the appropriate valve size, trim type, and pressure drop are selected.
