3 Their application range covers control tasks in process engineering and industrial applications as well as in supply and power plant modular system allows easy retrofitting and control valves consist of a valve and (pneumatic, electric, electrohydraulic or hand-operated) controlling purposes and travel indication, accessories, such as positioners, limit switches and solenoid valves, can ei-ther be attached directly or according to IEC 60534-6 (NAMUR rib) (see Information Sheet uT 8350 EN).The valve bodies are available in cast iron, spheroidal graph-ite iron, cast steel, cast stainless steel, cold-resisting steel, forged steel or forged stainless steel as well as special alloys. All parts of the valve and the pneumatic actuator housing in the completely corrosion-resistant version are made of stain-less steel.

4 Refer to the associated data sheets for 240 Series 240 control Valves are primarily used in the chemical industry. The valves are available as globe and three-way valves in valve sizes ranging from DN 15 to 300 (NPS to 12) and up to a pressure rating of PN 40 (Class 300).Standard versions of the valves are suitable for temperature ranges between 10 and +220 C (15 and 430 F). An insu-lating section allows the temperature range to be extended to 196 and +450 C (ANSI: 325 and +840 F).The plug stem is sealed either by a self-adjusting PTFE V-ring packing or an adjustable packing. To meet stricter emissions control requirements, a stainless steel bellows is used. The Type 3241 Valve can be equipped with a heating jacket that may also include the bellows 250 Series 250 control Valves are used when large valve sizes and/or high pressures are involved in process engineering, power plant or supply are manufactured in valve sizes DN 15 to 500 (NPS to 20) and pressure ratings of PN 16 to 400 (Class 150 to 2500).

5 In addition to globe, three-way and angle valves, cus-tomized valve constructions can be versions of the valves are suitable for temperature ranges between 10 and +220 C (15 and 430 F). The tem-perature range can, however, be extended by using an ad-justable high-temperature packing to a temperature range be-tween 10 and +350 C (15 and 660 F) and by using a bel-lows seal or an insulating section to a temperature range be-tween 196 and +550 C (ANSI: 325 and +1022 F).Series 250 Valves can be equipped with a heating 280 Series 280 Steam-converting Valves are used to reduce both the steam pressure and steam temperature to optimize plant operation and heat efficiency in process plants, for example, in refineries, food and beverage, tobacco or pulp and paper valves are based on Series 250 Valves fitted with a flow divider St III and an additional cooling water valves are available in valve sizes ranging from DN 50 to 500 (NPS 2 to 20), for pressure ratings of PN 16 to 160 (Class 150 to 900) and for temperatures up to 500 C (930 F).

6 Series 290 Series 290 control Valves are primarily used in the petro-chemical industry and process engineering due to their main-tenance-friendly properties. The seat is clamped into the valves to facilitate 290 Valves are only available in ANSI versions in valve sizes NPS to 8 and pressure ratings of Class 150 to 900. A bellows seal or insulating section allows the valves to be used in temperature ranges between 196 and +450 C ( 325 and +842 F) depending on the material equipment includes flow dividers, heating jackets and balanced plugs. Furthermore, Series 290 Valves can be designed to meet NACE requirements for sour V2001 The Series V2001 Valves are available as globe valves or as three-way valves for mixing or diverting service. They are manufactured in valve sizes DN 15 to 100 (NPS to 4) and pressure ratings of PN 16 to 400 (Class 150 and 300).

7 The standard versions of these valves are suitable for temperature ranges from 10 to +220 C (14 to 430 F). The use of an in-sulating section extends the temperature range to 300 C (572 F).Series V2001 Valves are primarily designed for use in me-chanical and plant engineering. A special attribute of the Type 3531 and Type 3535 Valves is their use in heat transfer applications using organic media ( heat transfer oil). The Type 3321 and Type 3323 Valves are suitable for liquids, gases and steam up to 350 C (660 F).The standard version can also be fitted with additional equip-ment, such as bellows seals, insulating sections and flow for special applicationsThese valves are designed for special requirements. Such valves include cryogenic, food processing, diaphragm and micro-flow K 30 EN catalog on components for the food processing and pharmaceutical industries contains details on hygienic and aseptic T 8000-1 ENTechnical dataTable 1: Series 240 Valves and valves for special applicationsValveSeries 240 For special applicationsType324132443248324633513510 -DIN-ANSI-Gas-Oil-T VData Sheet T.
