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 (1⁄2" to 8"). When used in conjunction
with a pneumatic or electric linear actuator they provide characterized modulating or
on / off control.

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.
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 JE control valve. With the exception of trim type, the JE, JF and JL control
valves are identical.
