How it works:
A: When the safety valve requires open, unscrew the protective cover (such as the middle guard screw hole, and put him in the rotation linkage rod using the handle), pull the handle, the valve opens.
B: When the safety valve need to close when the coil power of not more than 30 seconds, turn off the valve quickly within 1 second.
Special features:
Signal feedback: When the valve is opened, the signal common line and signal lines connected to open; when the valve is closed, the signal common line and off signal line connected.
Manual functions: safety valve need to close time, unscrew the hand guard, forced by manual handle, the valve closed.
