Product Introduction

ANSI Class300LB American standard swing flange check valve CF8/CF8M/WCHANSI Class300LB American standard swing flange check valve is a one-way valve, also known as a check valve, which prevents the medium from flowing back in the pipeline. It adopts a built-in rocker arm swing structure. All opening and closing components 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 for the middle flange, there are no leakage points overall, eliminating the possibility of valve leakage. The connection between the swing arm and the valve disc of the rotary check valve adopts a spherical connection structure, which gives the valve disc a certain degree of freedom within a 360 degree range and appropriate micro position compensation. Suitable for cleaning media, not suitable for media containing solid particles and high viscosity.
