KTM 512

High-performing and compact, these pressure-independent control valves for variable flow heating and cooling systems are particularly effective in situations requiring high temperatures and/or pressure drops. They are also suitable for use on the secondary side in district heating and comfort cooling systems. Rust protection is assured due to the electrophoretically painted ductile iron body, while the plug delivers valve characteristic, suitable for modulating control.

Pressure independent balancing and control valve – DN 15-125

High-performing and compact, these pressure-independent control valves for variable flow heating and cooling systems are particularly effective in situations requiring high temperatures and/or pressure drops. They are also suitable for use on the secondary side in district heating and comfort cooling systems. Rust protection is assured due to the electrophoretically painted ductile iron body, while the plug delivers valve characteristic, suitable for modulating control.

Key features

Inline design

Inline flow allows high pressure drops without noise.

Adjustable flow

Ensures the design flow.

Adapters

For use with most available actuators.

Surface treatment:

Electrophoretic painting.

Marking:

IMI TA, DN, PN, Kvs, material and flow direction arrow.

Connection:

DN 15-50:
Male threads according to ISO 228.
DN 65-125:
Flanges according to EN-1092-2, type 21. Face to face length according to EN 558 series 1.

Max. lift of the control valve:

DN 15-50: 10 mm
DN 65-125: 20 mm

Actuators:

DN 15-50: TA-Slider 500
DN 65-125: TA-Slider 750
DN 80-125 HF: TA-Slider 1250
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.
