Smoke Resistance Control Valve:
1.Control voltage: DC 24V
2.Working current: 0.3A
3.drag coefficient: less 0.5

Smoke Resistance Control Valve Specifications:

1.The valve usually keeps closing. The smoke sensor will send an electrical signal through the control center when there is a fire. The electromagnetic in the executive agency powers on and operates. At the same time, the valve opens automatically, and outputs open electrical signals.

2.The valve can be opened manually.

3.The valve can reset manually after operation.
