Control Valves Globe Control Valves 94 SPIRA-TROL 1/2" to 4" ANSI Two-port KEA, KFA and KLA Control Valves Description SPIRA-TROL is a range of two-port single seat globe valves with cage retained seats conforming to ASME/ANSI standards. These valves are available in three body materials in sizes ranging from 1/2" to 4". When used in conjunction with a pneumatic or electric linear actuator they provide characterised modulating or on/off control. SPIRA-TROL valve characteristic - options: Equal percentage (E) - Suitable for most modulating process control KEA applications providing good control at all flowrates. KFA Fast opening (F) - For on/off applications only. Linear (L) - Primarily for liquid flow control where the differential KLA pressure across the valve is constant. Important note: Throughout this document, reference has been made to the standard KEA control valve. With the exception of trim type, the KEA, KFA and KLA control valves are identical. SPIRA-TROL valve options: Graphite packing - High temperature applications Bellows / PTFE - Zero emissions Stem sealing Bellows / graphite - Zero emissions + High temperatures PTFE seals - Standard Metal-to-metal 431 stainless steel - standard 316L stainless steel Seating Soft seating PTFE for tight shut-off Hard facing 316L stainless steel with Stellite 6 facing - for more arduous applications Standard bonnet Bonnet type Extended bonnet for large pipe lagging or hot / cold applications Trim Standard Low noise SPIRA-TROL two-port valves are compatible with the following actuators and positioners: Electric EL5600, Rotork CVL, Belimo NV and AF Pneumatic PN1000 and PN9000 series PP5 (pneumatic) or EP5 (electro-pneumatic) ISP5 (intrinsically safe electro-pneumatic) Positioners SP400/SP500 (microprocessor based electro-pneumatic) SP300 (digital communications) Refer to the relevant Technical Information sheet for further details. Sizes and pipe connections Local regulation may restrict the use of this product below the conditions quoted. Limiting conditions refer to standard connections only. In the interests of development and improvement of the product, we reserve the right to change the specification.
