Pan-plugging seal is a kind of high-performance seal with special spring in U-type Teflon (PTFE). It relies on the excellent physical and chemical properties of Teflon to maintain the anticipated sealing performance. Next, we will learn about the characteristics and application of the universal plugging seal.

The sealing principle of universal plugging seal:

PTFE plate spring U-type sealing ring (universal sealing) is made up of proper spring tension and system fluid pressure. The sealing lip is pushed out and the sealing metal surface is gently pressed to form a very excellent sealing effect.

Characteristic of blocking:

1. Sealing performance is not affected by insufficient lubrication at start-up.

2. Effective Reduction of Abrasion and Friction Resistance

3. Through the matching of different sealing materials and springs, different sealing forces can be displayed to meet various application requirements.

4. Made by special CNC processing machine, no die cost - especially suitable for a small number of various seals.

5. Chemical corrosion resistance and heat resistance are far superior to those of commonly used rubber seals, with stable size and no deterioration of sealing performance due to volume swelling or shrinkage.

6. The structure is exquisite and can be installed in standard O-ring groove, which greatly improves the sealing ability and service life.

7. Seal grooves can be filled with any anti-pollution material (such as silica gel) - but not suitable for radiation environment

8. Because the sealing material is Teflon, which is very clean and does not pollute the process, the friction coefficient is very low. Even at very low speed, it is very smooth and has no "hysteresis effect".

9. Starting friction resistance is small, even if the shutdown time is long or intermittent operation, it can maintain low starting force performance.

10. The special seals developed for high temperature corrosion, difficult lubrication and low friction application environment, different combinations of Teflon composites, advanced engineering plastics and corrosion-resistant metal springs, can fully meet the increasingly stringent diversified needs of industry.

Typical application examples of blocking:

1. Axial Seals for Rotary Joints of Loading and Unloading Arms

2. Seals for Painting Valves or Other Painting Systems

3. Seals for Vacuum Pumping

4. Filling equipment for beverages, water and beer (e.g. filling valves) and seals for food industry

5. Seals for automotive and aerospace industries, such as power steering engines

6. Seals for measuring equipment (low friction, long service life)

7. Seals for other process equipment or pressure vessels
