DN15A manual reset 1/2" Nickel-plated brass gas emergency shut off
solenoid valves for home DC6-24V
This valve mainly be used in every kind of fuel gas pipeline being
in danger (divulging, breakage) to give an alarm and quick
closedown automatically, especially suitable for inflammable gas
pipeline's safety and protection system. May match with each kind
of alarm apparatus.

The valve is a series of gas emergency shut off solenoid valves,
specially designed as gas pipe breaker for emergency use . It can
be connected with gas leaking detection sensor ,fire alarm circuit
or other intelligent sensor modules so that on site or remote shut
down on gas supply (manually or automatically) is possible , hence
ensuring the safety on gas usage .the valve features an auto-close
when strong vibration is detected .After close,manual operation is
required to turn on the valve. This feature meets safety
regulations in the event of an accident.
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
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.
Note:the valve may not to be pulled up if gas pressure on both
sides(inlet and outlet) is not balanced. Take necessary action to
ensure that they are balanced ,then pull the knob up again,force
pulling it may result in damage to the valve.
3.The valve will close automatically when it detects strong
vibrations. Should this feature fails, notify the contractor or
manufacture for repair.
4.After closing ,careful inspection is required.Do exercise caution
when the valve needs to be turned on again.
1. Only request contractor can install this valve.
2 .The valve must be installed after the indoor main valve.
3 .A valve should be installed in the gas flow direction marked on
the valve body. The coil must not be placed in downward position A
valve may be installed horizontally or vertically.
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.
9.Our guarantee does not include any damage to the valve or loss of
parts due to keeping or actions in violative regulations.
