Spira-trol TM Two-port Control Valves EN Standard JE, JF and JL DN15 to DN200 and ASME Standard JEA, JFA and JLA ½" to 8"
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 DN200 ( ½ " to 8"). When used in conjunction with a pneumatic or electric linear actuator they provide characterized modulating or on/off control. Spira-trol TM valve characteristic - options: Equal percentage (E) - Suitable for most modulating process control applications providing good control at all flowrates. JF Fast opening (F) - For on /off applications only. JE
4.1 1
Linear (L) - Primarily for liquid flow control where the differential pressures across the valve is constant.
JL
Important note: Throughout this document, reference has been made to the standard JE control valve. With the exception of trim type, the JE, JF and JL control valves are identical.
