Cast iron flanged plug valve 11ch8bk Pn 10

Flanged cast iron plug valves 11ch8bk PN 10 are used as a shut-off device to block the flow of the working medium in pipelines. They are used in heat and water supply systems, as well as in industry, utilities, oil pipelines. The main working environments for these valves include water and oil (up to +100°С).

Design and operating principle

11ch8bk valve belongs to the category of cone plug valves. Its design includes the following elements:

• The shut-off element is made in the form of a truncated cone with a trapezoidal hole inside.
• In the open position, the openings of the branches coincide with the opening of the plug, ensuring free passage of the working medium.
• The sealing surfaces consist of conical surfaces of the outer plane of the plug and the inner surface of the body.
• A special lubricant is applied between the body and the plug to ensure tightness, prevent corrosion and facilitate the rotation of the plug.

Operating principle is based on the rotation of the plug around its axis. In the closed position, the axis of the passage hole is perpendicular to the axis of the pipeline, which completely blocks the flow.

Materials of manufacture

The main materials of the valve:

• Body: cast iron.
• Plug: cast iron.
• Spindle seal: impregnated asbestos.

Cast iron as a material provides high structural strength at a relatively low costs.

Advantages of the 11ch8bk valve

1. Simplicity of design and reliability in operation.
2. Low cost due to the use of cast iron as the main material.
3. Small dimensions and low hydraulic resistance.
4. Possibility of installation in any position relative to the pipeline.

It is worth considering the need to apply significant effort during manual control due to high torques.

Application

1. Utilities (water supply).
2. Industrial equipment (heat carriers).
3. Oil pipelines.

Plug valve 11ch8bk is a reliable solution for shutting off the flow of the working medium in various pipeline systems due to its robust design, affordable price and ease of maintenance.
