1.Product Description
The material of domestic lpg natural gas emergency shut off solenoid valve is aluminum alloy, besides brass valve body is option. All the materials are anti corrosion painted. It can resist the high heat, rust and humidty. The durable long lifespan and almost no after sale maintenance, letting it be the hot sale products.
2.Working Principle
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.
3.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 inlet 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.
