What are the advantages of flanged ball valves?！

2024-09-30

Ball valve and gate valve are the same type of valve, the difference is that its closing part is a ball, the ball is rotated around the body core line to achieve the opening and closing of a valve. Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Flange ball valve standard GB/T21465-2008 "Valve terminology" is defined as: the opening and closing parts (spheres) are driven by the valve stem and rotate around the axis of the valve stem.

What are the characteristics of the American standard flanged ball valve in structure?

American standard flange ball valve in the pipeline is mainly used to cut off, distribute and change the direction of medium flow. Its large pivot structure ensures the accurate center position of the ball under high pressure to ensure the good operating performance of the valve; The standard valve seat adopts spring structure to push the valve seat to the ball to ensure good two-way sealing performance. Using the built-in discharge valve, the body cavity can be discharged outward; The pivot adopts anti-blowout protection structure to effectively prevent leakage; Low friction coefficient bearing, so

What is the difference between the nominal pressure of the national standard valve and the pressure of the American standard valve?

National standard valve nominal pressure and American standard valve pressure there are the following differences: ◆ Pressure expression method and unit: the national standard valve pressure rating unit is MPa (MPA), the American standard valve pressure rating unit is LB (pound class) 2. For example, the nominal pressure of the national standard valve may be marked as 1.6MPa, 2.5MPa, etc., and the American standard valve is marked as 150LB, 300LB, etc. ◆ Pressure corresponding to reference temperature: in the national standard system, PN refers to the corresponding temperature at 120℃
