Features & Benefits

Inline design

Inline flow allows high pressure drops without noise.

Adjustable flow

Ensures the design flow.

Adapters

For use with most available actuators.

Technical description

Size 2 1/2" - 5": Flanges according to ASME/ANSI B16.42 Class 150.

Actuators:

1/2 - 2": TA-Slider 500
2 1/2": TA-Slider 750*
3" LF/NF: TA-Slider 750*
3" HF: TA-Slider 1600*
4" LF: TA-Slider 750*
4" NF/HF: TA-Slider 1600*
5": TA-Slider 1600*

*) Adapter 52 757-907 needed.

For more details on actuators, see separate technical leaflets.

KTM 512 can be equipped with adapters for the most common actuators - see "Adapters for actuators".
The max. lift of the actuator must be checked. In the case of a shorter lift the maximum achieved flow will be decreased. Consult your local sales office for details.
