EMERSON. KEYSTONE SLURRY CONTROL VALVES FIGURE 638 SERIES E/SERIES 2 The F638 SE/S2 is an extreme heavy duty slurry control valve, with an extended body style and replaceable body sleeve. • Series E for heavy duty service • Series 2 for arduous duty service FEATURES GENERAL APPLICATION • Bauxite slurries • Coal washeries • Tailing dispersal • Cement • Caustic • Sugar industry and tailings • Mud and sand dispersal • Mineral sands Size range: Temperature rating: Pressure rating: Max AP: Standard flange drilling: • Heavy robust construction. • Full repairability with replaceable internals for significantly extending valve life. • Extended body for protection of down stream piping. • Chrome Iron internals on the Series 2 coated with tungsten carbide. • Series 2 features tungsten carbide disc end spacers. • Swing through disc for minimal leakage at elevated temperatures. • Wing-style disc for optimum flow and wear resistance. • Venturi liner for improved flow control and thicker liner for wear resistance. • Improved mechanical seal to prevent the ingress of media to the bearing journals. • KTFE stem seals for ultimate resistance against caustic and acid applications. • Superior multiple stem seals. • Standardized mounting and drive adaptor connection allowing direct mounting of Keystone actuators and also allows for in-line actuator removal. • Manufactured under quality system ISO 9001:2000. Certificate No Mel 0400133. • Available with PED approval. Cert No: 0038/PED/MUM/0710020/1. Flow diagram The extended body design of the F638 valve protects downstream piping from wear when used on high velocity control applications. Emerson.com/FinalControl © 2017 Emerson.

Mass determined on materials used. Kv = The flow rate of water in m3/hr that will pass through a valve with a different pressure drop of 1 bar (100 kPa) at 20°C. Cv = 1.155 Kv Dimensions are nominal to ±1 mm.

(Refer to Emerson valve manual for further information). The following guidelines are considered to be conservative and can confidently be used for routine duties. If you have any...
