The illustrious FT series air volume control damper, featuring the Exhaust Valve PY-1(SD) PY-5(SD), is a remarkable solution meticulously designed for smoke exhaust systems. Ideal for installation within the air ducts, this sophisticated valve remains closed under normal conditions. In the event of a fire, as soon as a fire alarm signal is relayed from a smoke sensor, the control center promptly activates the electrical signal to the valve's electromagnet, ensuring swift opening for efficient smoke extraction. Moreover, this valve can be manually opened for immediate response. Operational excellence is guaranteed with a telecom number DC24V ±2.4V that activates the valve, along with a feature for manual reset. It provides output for open signal post-action and offers interlocking capabilities with other equipment as per user specifications. Please note that this exhaust valve does not come equipped with a temperature sensor.
