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.

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.

Installation Requirements

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.

Wiring Requirements

1.Cable:dual core.3×0.75mm2 Or above

2. Length of cable < 50meters

Review by: Yuri S.
I shop online a lot but every now and then you don’t get what you expect. This time I was delivered what I was looking for.

The thing that drew my attention was the design. Who could expect I’d see merchandise, a model like this at a web store. So I must say, I came to like the thing at first view. Though I I had certain doubts about the quality when I just purchased it. I kind of knew I’d better not expect fine quality. It’s a relief I happened to be wrong.

When I got the package I was bewildered by the quality of the thing. In my judgment, it’s not easy to purchase such product made of decent materials. the merch turned out to be a great luck! it’s great I bought it. Never expected I’d get something worthy on the web. I discovered some similar items from other sellers but I couldn’t find anything suitable quality. Either the outward appearance or the quality looked too low so I decided not to take the risk.

I was searching for a present for my partner and I was lucky I bought this from this seller. I read somewhere the merchandise is really popular among some people. My soul mate has been using it for 4 days now and seems very happy. So guess I was lucky to come upon this web page.
