The company "Leader-M" sells not only pipes of various types, but also accessories for them. Among the assortment there are shut-off valves — devices that are partially placed in the cavity of the pipe and serve to close its lumen. As a result, the flow of the working medium is interrupted and a part of the pipeline is isolated.
Shut-off valves are an indispensable structural element of any pipeline that ensures its control. In complex systems, they fulfill a number of important functions: they shut off unwanted flow of the medium as well as direct the flow in a given direction and prevent it from moving in the opposite direction. Shut-off and control valves allow to maintain the necessary pressure in the pipeline and to shut it off during repair work.
There are several types of shut-off and control valves, which differ in their design features, purpose and scope of application. The performance of the device depends on the working medium in which it operates and the conditions.
The term "shut-off valves" refers to a number of devices which, regardless of their type, operate according to a common principle. The main working element of the design is the gate valve, designed to close the lumen of the pipe and ensure the interruption of its internal flow. The gate can be flat in the form of a chimney, wedge-shaped, spherical, equipped with a hole in the central part, etc. In the open position, it does not prevent the flow of the working medium through the lumen of the pipe, and in the closed position it completely closes the lumen. The shutter is connected with a control element, the role of which is played by a handle or a hand wheel. When the control element is rotated, the gate moves from the closed state to the open state, and vice versa. The main parts of the device are placed in a robust housing and mounted directly on the pipe.
Depending on the method of installation fittings are:
Additional insulation inside the body of the moving elements and the closure provides the required level of tightness of the fixture.
