ATH90 • Airtight bypass T valves

Circular air-tight bypass T control valve according to EN 12237 with manual quadrant and rubber sealing. Airtight valve according EN 1751 Class 4. The airthightness is also determined by the mounting on the construction site.

• Galvanized steel

• Controle valve type ATH90 can be motorized with a actuator type LM, NM, LF or NF/SF
• If used with servomotor type LM, a mounting plate type MP-LM is obligatory. An axe extension type AEX-12/M6 100 mm is necessary for ATH90 80 until ATH90 250
• If used with servomotor type NM, a mounting plate type MP-NM is obligatory. An axe extension type AEX-12/M6 100 mm is necessary for ATH90 80 until ATH90 250
• If used with servomotor type LF, a mounting plate type MP-LF is obligatory. An axe extension type AEX-12/M6 100 mm is necessary for ATH90 80 until ATH90 250
• If used with servomotor type NF or SF, a mounting plate type MP-NF/SF is obligatory. An axe extension type AEX-12/M6 100 mm is necessary for ATH90 80 until ATH90 200
• An actuator with more than 5Nm (NM, NF or SF) is recommended for ATH90 size 315

• A circular air-tight bypass T control valve with manual quadrant is used for a good regulation of the air flow in 2 directions. The valve can be motorized with actuator type Belimo LM or NM. The manual handle will be replaced by mounting plate Type MP-LM or MP-NM. An Axle extention AEX-12/M6 100mm is recommended.
• Type ATH90
