Light weight: the fire valve body is made of high-grade nodular black cast iron, which can reduce the weight of traditional valves by about 20% ~ 30%, and is easy to install and maintain.

Flat bottom type gate seat: after the traditional valve is washed with water, foreign matters such as stone, wood block, cement, iron filings and sundries are deposited in the groove of the valve bottom, which is easy to cause the phenomenon of water leakage due to being unable to close tightly. The bottom of the elastic seat sealed valve is designed with the same flat bottom as the water pipe machine, which is not easy to cause the accumulation of sundries, so that the fluid is unobstructed.

Overall rubber coating: the ram adopts high-quality rubber for overall internal and external rubber. The first-class rubber vulcanization technology in Europe enables the RAM after vulcanization to ensure accurate geometric dimensions. Moreover, the rubber and the ductile cast RAM are next to each other firmly, which is not easy to fall off and has good elastic memory.

Precision casting valve body: the valve body is made of precision casting, and the precise geometry makes the valve body without any finishing to ensure the tightness of the valve.

The fire valve has the following advantages:

1. The fluid resistance is small, and the sealing surface is brushed and eroded by the medium.

2. Opening and closing is more labor-saving.

3. The flow direction of the medium is not limited, does not disturb the flow and does not reduce the pressure.

4. The utility model has the advantages of simple shape, short structure length, good manufacturing technology and wide application range.

The disadvantages of fire valves are as follows:

1. It is easy to cause erosion and abrasion between sealing surfaces, so it is difficult to maintain.

2. The overall dimension is large, so it needs a certain space for opening and closing, and the opening and closing time is long.

3. The structure is complex.
