EL7200 Series Electric Actuators
Description EL7200 series electric actuators are available for use with the following supply voltages: 230 Vac, 115 Vac and 24 Vac. This range of electric actuators has three user-configurable control modes as standard: - (VMD) Valve Motor Drive,
- (0 / 4 - 20 mA) modulating control or - (0 / 2 - 10 Vdc) modulating control. When they have been fitted to a control valve they provide modulating control or on / off action. EL7200 series electric actuators can be used with the following valves:
4.3 67
Spira-trol TM BX, BM, SB, KA, KB, KC and NS TW valves (DN20 - DN50) QLD and QLM (DN15 - DN50)
2-port
3-port
EL7021
Mounting flange (DN15 - DN50)
EL7200
EL7020
Linkage LE, KE Series (DN15 - DN50)
Adaptor
EL7012
For self-acting valves (DN15 - DN50)
Operation The drive mechanism consists of a stepper motor and a planetary gearbox that converts a rotary motion to a linear motion. An integrally installed contactless hall-sensor for permanent positioning control, switches off the motor in the maximum travel position of the valve.
Options and accessories IP65 construction . 24 Vdc motor for rectified ac.
