2 Introduction Optional test port NPT ¼" Anti-blowout stem design Guided stem PN 16 modified PTFE bellows seal,as standard configuration Metal to metal body/bonnet connection for defined compression of the gasket Liner thickness minimum 5mm (3,5 mm for DN15 / ½" and DN 20 / ¾") T-groove liner connection Threaded plug and seat interchangeable with other plug and seat sizes Optional Hastelloy C-276 plug and seat inserts for small Kvs / Cvs-values DIN and ANSI bodies and connections Figure 1: Body Assembly The new series control valve completes the range of lined valves within the FLOWSERVE corporation. Many years of experience in the manufacture of lined ball and plug valves and the sophisticated experience of manufacturing excellent reproducible trims for linear valves are combined in this new product. High quality lining materials such as PFA (standard), PVDF, PP, ETFE and FEP as well as PFA antistatic cover most mediums and applications. The revolutionary PTFE bellows design allows a standard pressure rating of PN 16. The increased flow capacity means that the most economical valve can be chosen for the application. 2

3 Features and Benefits Features Liner materials Liner thickness Liner connection Bellows seal Hastelloy plug and seat inserts Face-to-Face Safety Benefits High Quality liner materials PFA (standard), FEP, PVDF, PP, ETFE for most corrosive applications. A minimum liner material thickness of 3,5-5 mm provides highest protection from the medium. T-grooves ensure a positive mechanical connection between the liner material and the valve body. Standard PN 16 bellows seal manufactured from modified PTFE permit universal valve applications. Hastelloy C276 plug and seat inserts for small Kvs/Cv values. Reproducible Kvs/Cv values and characteristics as well as large rangeability. DIN bodies PN 16, integral flanges, DIN face-to-face dimensions DIN bodies with integral flanges drilled in accordance with ANSI Class 150. ANSI bodies with ANSI face-to-face dimensions and ANSI Class 150 flanges. Anti-blowout stem design for all sizes, optional test connection for bellows seal leak detection and safety packing ensure maximum safety Trim Design Threaded plug and seat design for easy replacement and maintenance. Excellent reproduceable trims and Cv-values based on long term experience even for small and very small Cv-values Figure 2: Plug and seat PTFE Figure 3: Hastelloy plug and seat inserts 3

4 Lining Materials The liner material, the seat and the bellows seal are the only parts which are in contact with the medium. High quality lining materials such as PFA, (Perfluoroalkoxy resin) protect the metal parts of the valve assembly. T-grooves provide an extremly positive connection between the liner and the valve metal body, especially important in vacuum applications. Liner thickness is at least 5mm (3,5 mm liner thickness for DN 15 / 1 /2 and DN 20 / 3 /4 ). Liner materials are available in most common combinations. PFA, FEP, PP, PVDF ETFE or antistatic PFA cover most application requirements. Figure 4: Pressure Temperature Diagram PFA FEP PP PFA FEP Figure 5: Vacuum Temperature Diagram 4
