Control valves

4.1.43

Spira-trol valve characteristic - options:

LE and LEA Equal percentage (E) - Suitable for most modulating process control applications providing good control at all flowrates.

LF and LFA Fast opening (F) - For on/ off applications only.

LL and LLA 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 LE or LEA control valve. With the exception of

trim type, the LE, LEA, LF, LFA, LL and LLA control valves are identical.
