EN 1092-2 Ductile iron flange elastic wedge gate valve with good air tightness
How the gate valve works
The working principle of the gate valve is to lift or lower the valve plate connected with the valve stem by turning the handwheel and the thread of the valve stem to advance and retreat, so as to achieve the effect of opening and closing.
Gate valve advantages
1. Good sealing performance: The sealing surface of the gate valve is larger, the flow resistance is small, and the opening and closing are more labor-saving.
2. Low fluid resistance: The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small.
3. Labor-saving opening: The direction of movement of the ram is perpendicular to the direction of medium flow, and it is labor-saving to open and close.
4. Wide range of application: Suitable for large-diameter pipelines and equipment, not limited by the flow direction of the medium, with the characteristics of double flow direction.
5. Compact structure: The gate valve has compact structure, good rigidity, smooth channel, small flow resistance, stainless steel and cemented carbide sealing surface, and long service life.
Gate valve installation method
1. Install the valve on the pipeline to ensure that the flange connection is flat and smooth to ensure the sealing performance.
2. According to the requirements of the pipeline system, select the appropriate installation location to ensure the convenience of operation and maintenance.
3. During the installation process, pay special attention to the opening and closing direction of the valve to ensure that the fluid flow direction is correct.
4. When tightening the bolts, use even force to avoid being too tight or too loose.
