Electronic Actuators for Control Valves

The world of process control has mostly relied upon

pneumatic linear actuators for many years. Advances in

electric actuators, especially electronic actuators, have

achieved similar functionality as pneumatics with the added

advantages of electrical operation. Flowserve Limitorque

introduced the MX, the first multi-turn electronic,

non-intrusive actuator with an absolute encoder, almost

20 years ago. The QXM, also with an absolute B.I.S.T (Built

In Self-Test) encoder followed; it uses a brushless DCV

motor (BLDC) specifically designed for the choke and control

valve industry.

In order to meet the demands of the choke and control

valve markets, a linear base can be added to complement

the MX and QXM products to provide a linear output. The

LB (Linear Base) is available in two sizes and can sustain

thrust up to 25 000 lb/109 kN. Please see Linear Base 1 and

2 Selection Tables for the ratings of LB1 and LB2 when

combined with either the MX or QXM products.
