H44T-16Swing Check Valvealso known ascheck valveOr check valve, its role is to prevent the backflow of the medium in the pipeline. The opening and closing parts rely on the flow of media and the force of their own open or close to prevent the backflow of the medium valve calledcheck valveThe check valve belongs to the automatic valve category. Check valve belongs to the automatic valve category, mainly used in one-way flow of media on the pipeline, only allows the medium to flow in one direction to prevent accidents. This type of valve in the pipeline should generally be installed horizontally.
Product Features
The rotary check valve adopts internal rocker arm rotary structure, all the opening and closing parts of the valve are installed inside the valve body, do not penetrate the valve body, in addition to the middle flange parts with sealing gaskets and sealing rings, there is no external leakage points, to eliminate the possibility of valve leakage. Swing check valve rocker arm and valve flap connection with spherical connection structure, so that the valve flap in the 360-degree range has a certain degree of freedom, there is an appropriate amount of compensation for the position, suitable for clean media, should not be used for solid particles and viscosity of the media.
