Spira-trolTM Two-port Control Valves
EN Standard KE, KF and KL DN15 to DN300 and
ASME Standard KEA, KFA and KLA ½" to 12"
Description
Spira-trolTM 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 DN300 (½" to 12"). When used in
conjunction with a pneumatic or electric linear actuator they
provide characterized modulating or on / off control.

Spira-trolTM valve characteristic - options:
KE and KEA Equal percentage (E) - Suitable for most modulating process control applications providing good control at all flowrates.
KF and KFA
Fast opening (F) - For 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 KE or KEA control valve. With the exception of
trim type, the KE, KEA, KF, KFA, KL and KLA control valves are identical.
