Cast Steel B.B Rising Stem Flange Gate Valve

Products Description :

The cast steel B.B rising flange gate valve uses a flexible ram to produce a slight elastic deformation compensation effect to achieve a good sealing effect. The valve has the advantages of light switch, reliable sealing, good elastic memory and long service life. Can be widely used in tap water, sewage, construction, petroleum, chemical, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy systems and other body pipelines as a regulating and intercepting device.

API 600 Cast Steel Rising Stem Flange Ends Gate Valve

Features

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

2, opening and closing is more labor-saving.

3. The flow direction of the medium is not restricted, no disturbance, no pressure reduction.

4. Simple shape, short structure length, good manufacturing process and wide application range.

Installation Precautions

1) The installation position, height, and import and export direction must meet the design requirements, and the connection should be firm and tight.

2) All kinds of manual valves installed on the insulated pipe, the handles shall not be downward.

3) The visual inspection must be carried out before the valve is installed. The nameplate of the valve should comply with the current national standard "General Valve Mark" GB 12220. For valves with a working pressure greater than 1.0 MPa and a shut-off effect on the main pipe, the strength and tight performance tests shall be carried out before installation, and shall be used after passing the test. In the strength test, the test pressure is 1.5 times the nominal pressure, the duration is not less than 5 min, and the valve casing and the packing should be free of leakage. In the rigorous test, the test pressure is 1.1 times of the nominal pressure; the test pressure shall meet the requirements of GB 50243 in the duration of the test, and the leakage of the valve sealing surface shall be qualified.
