Stop valves

Valves are required structural element of any pipeline to ensure its management. In complex systems it performs several important functions: serves to cover unwanted current environment, as well as to direct the flow in a given direction and prevent him from movement in the opposite direction. Valve allows to maintain the necessary pipeline pressure and to close it during the renovations.

There are several types of valves that vary in their design features, purpose and scope. The performance characteristics of the device depend on the working environment in which it operates, and conditions.

Design features

The term «valving» refers to the variety of devices regardless of their type, operate on the general principle. The main working element of the design is a shutter designed to shut off the lumen of the pipe and ensure the interruption of her inner power. The shutter can be flat in the form of a gate, tapered, spherical, equipped with a hole in the central part, etc. In the open position it prevents the flow of working fluid through the lumen of the tube, and when closing the gap completely covers. The shutter is associated with the control element, which is the arm or the wheel. Upon rotation of the control shutter is in motion and moves from a closed position to an open position, and vice versa. The main parts of the device are placed in a durable case and are mounted directly on the pipe.

Depending on the method of installation, the armature can be:

  • threaded;

  • flange;

  • welded.

Additional insulation inside the hull moving parts, and the shutter provides the required level of tightness of fit.
