Copyright 216 TI-S24-71 CH Issue 9 Spira-trol TM Two-port Control Valves EN Standard KE, KF and KL DN15 to DN3 and ASME Standard KEA, KFA and KLA ½" to 12" Description Spira-trol TM is a range of two-port single seat globe valves with cage retained seats conforming to EN and ASME standard. These valves are available in three body materials in sizes ranging from DN15 to DN3 (½" to 12"). When used in conjunction with a pneumatic or electric linear actuator they provide characterized modulating or on / off control.

2 Spira-trol TM valve characteristic - options: KE and KEA KF and KFA KL and KLA Equal percentage (E) - Suitable for most modulating process control applications providing good control at all flowrates. Fast opening (F) - For on / off applications only. Linear (L) - Primarily for liquid flow control where the differential pressures across the valve is constant. Important note: Throughout this document, reference has been made to the standard KE or KEA control valve. With the exception of trim type, the KE, KEA, KF, KFA, KL and KLA control valves are identical.
