SPIRA-TROL Two-port Control Valves ASME Standard LEA, LFA and LLA ½" to 4"
TI-S24-70-US 3.17
DescriptionSPIRA-TROL is a range of two-port single seat globe valves with cage retained seats conforming to ASME standard. These valves are available in three body materials in sizes ranging from ½" to 4". When used in conjunction with a pneumatic or electric linear actuator they provide characterized modulating or on / off control.

SPIRA-TROL Two-port Control Valves ASME Standard LEA, LFA and LLA ½" to 4"
SPIRA-TROL valve characteristic - options:LEA Equal percentage (E) - Suitable for most modulating process control applications providing good control at all flowrates.
LFA Fast opening (F) - For on / off applications only.
LLA Linear (L) - Primarily for liquid flow control where the differential pressures across the valve are constant.
Important note: Throughout this document, reference has been made to the standard LEA control valve. With the exception of trim type, the LEA, LFA, and LLA control valves are identical.
SPIRA-TROL valve options: PTFE chevron seals Standard
Stem sealing Bellows / graphite secondary seals (D) Zero emissions and high temperature applications
Graphite packing High temperature applications
Metal-to-metal
431 stainless steel - standard
316L stainless steel
Seating Soft seating Up to 392°F - PTFE for Class VI shut-off
Hard facing 316L stainless steel with Stellite 6 facing - for more arduous applications
Bonnet type Standard bonnet
Extended bonnet for large pipe lagging or hot / cold applications
Trim Standard trim
Low noise and anti-cavitation trim (see TI-S24-59)
SPIRA-TROL valves are compatible with the following actuators and positioners:Electric EL7200, AEL5 and AEL6 series
Pneumatic PN1000, PN9000 and PN2000 series
PP5 (pneumatic) or EP5 (electropneumatic)
Positioners ISP5 (intrinsically safe electropneumatic)
SP400 and SP500 (microprocessor
based electropneumatic)
SP300 (digital communications)
Refer to the relevant Technical Information sheet for further details.
