Factory Price Non-Return Valve Piston Water Meter with Remote Transmission

The working principle of the water meter check valve is based on the action of fluid pressure. When a fluid (such as water) flows in the normal direction, the fluid pressure will open the valve disc, allowing the fluid to pass through. When the fluid attempts to flow in the opposite direction, the valve disc will automatically overlap under the action of fluid pressure, cutting off the reverse flow path of the fluid and thus preventing the backflow of water flow.
