Electric linear actuators for use with GCV control valves DN 15 to DN 100 AEL5 series
AEL5 series electric linear actuators are for use with LE, KE and JE two-port control valves, QL three-port valves and all bellows sealed options. Actuators will normally be supplied fitted to the control valve. When supplied separately, ensure the actuator selected is capable of giving the force necessary to close the two-port or three-port control valve against the expected differential pressure. See the appropriate product specific Technical Information Sheet for full details of the control valve.

Water Level Limiter Level Electrode NRG 16-50 S
The level electrode NRG 16-50 S is used in conjunction with level switch NRS 1-50 (de-energizing delay: 15 seconds) as water-level limiter for steam boilers and (pressurized) hot-water installations on board of seagoing vessels, mobile offshore platforms or river boats. Water level limiters switch off the heating when the water level falls below the set minimum level (low water).

Electropneumatic Smart Positioner SP500
The SP500 smart valve positioner is a loop powered device that is able to drive linear and quarter turn pneumatic valves. A 4-20 mA input signal determines the valve set point. Precise control is maintained through valve position feedback that automatically varies the pneumatic output pressure to overcome the effects of stem friction and flow forces to maintain desired valve position.

Level Switch NRS 1-56
The NRS 1-56 level switch measures using the conductivity principle and makes use of the electrical conductivity of the water to do this. The level switch is designed for different conductivities and for connection to four electrode rods in total.

Level Switch NRS 1-53
The level switch NRS 1-53 in conjunction with level electrodes NRG 16-.. and ER 5. is used as limit switch, for instance as water level limiter in steam boilers and (pressurized) hot-water installations. The level switch detects and indicates two low water levels (MIN 1, MIN 2). The level switch can work with following level electrodes: NRG 10-52, NRG 16-52, NRG 16-4 and ER 5.-1.
