Interflange сheck valves.

The interflange check valve is a shut-off device that is installed in pipelines to preserve the movement of the working medium in one direction and prevent water shocks.

Their main task is to block the flow of the transported medium if it begins to move in the opposite direction. The installation of the valve makes the movement of the medium safe for the system and helps to avoid accidents and severe consequences. The interflange check valve is used in engineering systems that transport liquid and gas media with different aggressiveness indices. In this regard, the check valve has many applications. These include: oil refining and chemical industries, water supply, heat supply of residential buildings and enterprises, ventilation systems. A feature of the device is that when installing them, no thread or other fasteners are required. Gaskets are used.

The interflange stainless check valve. Types of structures.

Depending on the type of shut - off element , cranes are divided into several categories:

• The interflange rotary check valve . They can be both percussive and unstressed. A spool is used as a locking element. They can be used in pipelines with large diameters and polluted media;
• The interflange spring check valve. The spring presses on the leaf when the flow parameters change and the valve closes. In the absence of pressure, the gate element returns to its original position. It is considered one of the most reliable options for installation in systems of any purpose;
• Interflange poppet check valve;
• The interflange disc check valve.

Carbon or stainless steel, as well as cast iron, are used to manufacture the mechanism. All materials used have wear resistance, high strength and low sensitivity to aggressive effects. It is worth choosing a device based on the parameters of the pipeline and the working medium, its pressure and temperature. In this case, it will serve its intended purpose for a long time, performing all the necessary functions.

Advantages of the double-leaf interflange check valve.

The interflange shut-off valve has a number of characteristic advantages that are noticeable during operation:

1. The possibility of installation in hard-to-reach areas in horizontal and vertical positions, since the valve shows the same efficiency of operation. Ease of installation, maintenance and disassembly;
2. High tightness and reliable protection of engineering communications from hydraulic shocks;
3. Compact dimensions that allow installation in small rooms and reduce the size of the engineering system itself;
4. Simplicity of the mechanism design;
5. They are manufactured in strict compliance with quality standards and specifications.

Design features ensure the reliability of the device and the ubiquity of the solution.
