Working Principal
When the switch is pressed, the capacitor discharges and provides an electric current so that a coil can generate strong magnetic held to pull down the valve, achieving the closing within one second.
Emergency Shut Off Valves
Operation instruction
1.There are two ways to close the valve:
(a)An electric impulse of 1 sec (DC 9V),or
(b)Press the red knob (must open the protective cover first ). After this operation, the valve remains closed.
Note: the protective cover must remain on position at all time.
2.When the valves is closed,manually pull the red knob up to turn it on .then the valve remains on.

4. the valve control wires should be connected correctly. White indicates positive while black stands for negative. Mismatch lends to fatal consequences.
5. During pipe maintenance, such as pressurized pipe cleaning .the valve should removed to avoid damages to the valve sealing.
6.During pressure tests, the valve should be turned on.
7.The valve's opening knob can be pulled up when equal pressure have been reached at the inler and the outlet of the valve.
8. Wrong polarity, wrong voltage or prolonged power on may damage the electromagnetic coil.
