Name:

Special For Oil Field Globe Valve

Category：

Globe valve

Remark:

Oilfield-specific valves are forced-sealed valves, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface to not leak. When the medium enters the valve from below the clapper, the resistance to be overcome by the operating force is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium. The diameter should be large, otherwise the failure to bend the valve stem will occur.
