1. Products Introduction
The PVC True Union check valve flanged is an automatic valve that can work automatically, do not require manual operation or other actions. The medium flows in the specified direction. When the flow pressure exceeds the opening pressure of the valve, the valve flap is pushed open under the action of the fluid pressure, thereby the medium pass by the valve. On the contrary, when the pipeline medium is reversed, the valve disc is pressed on the check valve body under the push of fluid pressure, and the valve is closed at this time, thereby cutting off the flow. And the greater the pressure of the backflow medium, the tighter the valve flap closes, and the better the sealing effect, which completely eliminates the possibility of medium backflow. The PVC True union swing check valve flanged is manufactured with flange, friendly installation with the metal pump and metal pipes with flanged. In short, the check valve is generally installed in the place to prevent the backflow of the medium when the valve is not closed. For example, the outlet of the common water pump will be installed with a check valve to prevent the high-pressure water from flowing backward into the water pump. S
The pvc true union swing check valve flanged from Sanking is flap type, which provides much more advantage then hemispherical structure or ball structure, even if there is only a drop of water/ fluid, it can be stopped, provides more safety and reliability. Horizontal or vertical installation are good for these series of valve. We supply the size from 1/2" to 2". ANSI/ JIS/ DIN are available.
