Pneumatic control valve fire control purposes have?

Fire protection valves are normally installed to adjust air duct on ventilation and air conditioning system, suitable for horizontal or vertical air duct. Smoke fire protection valves are normally installed in need to adjust the air volume or need electricity signal control valve closed duct on ventilation and air conditioning system. Suitable for horizontal or vertical air duct. Use pneumatic control valve applied in fire prevention requirement of ventilation and air conditioning duct wall level and vertical duct road, across the floor when there is a fire, actuators on the temperature sensor output, behind closed doors shut down automatically, control center 24 v power supply or close the valve manually, to prevent the spread of fire along the duct, normally open at ordinary times, ( Smoke fire pneumatic control valve and air regulation function) （ But make it explosion-proof type, pneumatic type) Low performance characteristics ( 1) Valve in a normally open state, when the air temperature of 70 ℃, the temperature sensor, the valve closed; （ 2) By DC24V power to close the valve; （ 3) Closed or manual reset manually; （ 4) Within the scope of 0 ° ~ 90 ° manually adjust the blade opening; （ 5) The output signal, the valve closed with other fire equipment interlocking.
