Copyright 215 TI-S24-71 CH Issue 7 N Standard K, K and KL DN15 to DN3 and ASM Standard KA, KA 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 N and ASM 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: K and KA qual percentage () - Suitable for most modulating process control applications providing good control at all flowrates. K and KA ast opening () - or on / off applications only. KL and KLA 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 K or KA control valve. With the exception of trim type, the K, KA, K, KA, KL and KLA control valves are identical.
