Product introduction:
A check valve refers to a type of valve with a circular valve disc as the opening and closing component, which acts to block the backflow of the medium by its own weight and medium pressure. It belongs to the category of automatic valves, also known as check valves, one-way valves, reflux valves, or isolation valves.
Single disc check valves are usually composed of a single disc, with the disc fixed to the valve cover, and the valve is opened and closed by the rotation of the disc. When the fluid flows forward, the valve disc rotates upwards and opens, allowing the fluid to pass freely; When the fluid flows in the opposite direction, the flap is subjected to the reaction force of the fluid, rotates downward, closes the valve, and prevents fluid backflow.

Product features:
1. The advantages of single disc check valve are simple structure, easy maintenance, and suitable for low flow rate and high pressure pipeline systems.
2. When choosing whether to use a single disc check valve or a double disc check valve, factors such as fluid characteristics, flow rate, and pressure need to be considered. Generally speaking, for low flow rate and low pressure pipeline systems, a single check valve is sufficient; For high flow rate and high pressure pipeline systems, double disc check valves are more suitable. Meanwhile, single disc check valves are suitable for one-way flow situations, while double disc check valves are suitable for two-way flow situations.
3. Single disc check valves and double disc check valves are two common types of check valves, and they have certain differences in design, working principle, and use. When choosing which type of check valve to use, it is necessary to make a reasonable decision based on the specific pipeline system situation, taking into account factors such as fluid characteristics, flow rate and pressure.
