Know the swing check valve

Swing check valves are used in pipelines with nominal pressure PN1.6～6.4MPa and working temperature -29～550℃ in various working conditions such as petroleum, chemical industry and thermal power station. Applicable medium: water, oil, steam, etc.

The swing check valve adopts a built-in rocker arm swing structure. All the opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body. Except for the sealing gasket and sealing ring used in the middle flange, the overall There is no leakage point, eliminating the possibility of valve leakage. The connection between the rocker arm and the valve disc of the swing check valve adopts a spherical connection structure, so that the valve disc has a certain degree of freedom within the range of 360 degrees, and has appropriate micro position compensation. Swing check valves have been widely used in chemical industry, metallurgy, pharmaceutical and other fields
