The valve is reverse rotary to prevent the opposite flow

To prevent the opposite flow of a certain medium in the pipeline, a reverse rotary valve was invented, the working disk of which rotates about its own axis. Usually it is installed directly after the pumping equipment, providing protection against a water hammer. This type of device is used more widely than other analogs of check valves. It is understood that with the return flow of the working medium, the special plug is lowered under the influence of its own mass. The reverse rotation valves can be made of cast iron, steel, brass, titanium and some other materials that have suitable properties.

Depending on the type of connection, the valve has been widely used in reverse rotary flanged, which is installed on the pipeline with the help of response elements and special fasteners. In the course of manufacturing, this type of product is tested for the strength of the shell and airtightness. Steel products can be made in four versions, as there are different grades of alloys. The required performance is chosen based on the aggressiveness of the working environment and operating conditions.

Water is very often used as a working medium, so a reverse rotary valve is required in most cases to control the flow of liquid in order to pass or block the channel. Such a device is primarily intended for pressure piping systems. It is able to work both under normal conditions and in all kinds of emergency situations. In this regard, it is allowed to be used even for industrial purposes. The principle of the device is to exclude the possibility of a current of water in the opposite direction, since this can lead to negative consequences.

Typically, a check valve for water is installed between the water meter assembly and the filter. That is, he must in any case be after the counter. It is recommended to mount it with a control plug downward to provide the best conditions for drainage. It is believed that the swivel mechanism is most convenient, because products with such a device can be installed on almost any pipe. A wide range of sizes allows you to do this without any problems.

Most often, the reverse rotary valve is mounted on the horizontal parts of the pipes, but it is quite feasible to install it on vertical pipelines. Unlike other types, it transfers contaminated water much better. The structure of this device includes several elements: body, cover, bolt, saddle and stem with flywheel. On the one hand, there is a special hole in the body that receives liquid. After the water enters, the rod moves the bolt, closing or opening the saddle opening. Passing through it, the liquid leaves on the other side. Installation of check valves is carried out taking into account the direction of movement of the liquid. The device should be easily accessible for maintenance.
