Latch — pipeline fittings in which the locking or regulating element moves perpendicular to an axis of a stream of a working environment. Latches — very widespread type of shutoff valves. They are widely applied practically on any technological and transport by truboprovodakhdiametra from 15 to 2000 millimeters in systems of housing and communal services, gazo-and water supply, oil pipelines, objects of power and many others with working pressure to 25 MPas and temperatures to 565 °C.
The wide circulation of latches is explained by a number of advantages of these devices among which:
comparative simplicity of a design;
rather small construction length;
possibility of application in various service conditions;
small hydraulic resistance.
The last quality does latches especially valuable to use in the main pipelines of which the continuous high-speed movement of the environment is characteristic.
