Valves 19ch24br PN 16 are check valves designed to prevent backflow of the working medium in pipelines. They are used in water supply and sanitation systems, and can also be used in sewerage systems. The main function of the valves is to ensure a one-way flow of the medium, which prevents possible emergency situations and protects pumping equipment from damage.
Design and operating principle
Check valve 19ch24br consists of a body, a flap (disk) and an axis. Flap is installed on axes inside the body with an eccentricity relative to the horizontal axis of symmetry. When the working medium is supplied under the flap, it opens due to the lifting force of the flow, holding it in the open position. When the pressure in front of the valve decreases or the flow stops, the flap closes under its own weight and the force of the reverse flow, preventing the medium from moving in the opposite direction.
Operating conditions
Check valve can be operated at an ambient temperature of at least -15°C. It is installed both on vertical pipelines (with the inlet pipe down) and on horizontal ones (the flap rotation axis is parallel to the horizontal plane).
Advantages
The advantages of the check valve 19ch24br include its simple design, durability and efficiency. It is an affordable option among similar products, which makes it a popular choice for utilities and water utilities.
