Structural features of z41h Japanese standard flange forged steel gate valve:

Forged steel gate valves have three body cover connection design forms. The first is the body cover bolted forged steel gate valve. For the valve designed according to this connection form, its body and bonnet are bolted and sealed with spiral wound gaskets, which has the advantage of easy maintenance. The second kind of forged steel gate valve is welded to the body cover. The valve designed according to this connection form has the advantage of no external leakage. The third is the pressure self tightening bonnet forged steel gate valve. For the valve designed according to this connection form, the valve body and bonnet are connected by screw mosquito, and the internal pressure self sealing ring is sealed. The advantage is that the greater the internal pressure, the better the sealing performance.

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

Opening and closing is labor-saving.

The flow direction of the medium is unrestricted, without disturbing the flow and reducing the pressure.

The utility model has the advantages of simple shape, short structural length, good manufacturability and wide application range.
