**Correctly understanding the difference between valve sealing rings and flange gaskets: professional selection ensures sealing performance**

In industrial pipeline systems, although sealing components are small, they play a crucial role in ensuring the safe operation of equipment and preventing medium leakage. Among them, valve sealing rings and flange gaskets are two common but easily confused sealing components. To help customers and technicians select and use more accurately, this article provides professional explanations of their functional characteristics and application scenarios.

**Valve sealing ring: a key sealing component inside the valve**

Valve sealing ring is a core component specially installed inside the valve (such as valve seat, valve disc, valve stem, etc.) or at some external interfaces to ensure reliable sealing of the valve in the closed state. Its main function is to effectively block the passage of medium when the valve is closed, prevent fluid leakage from the inside of the valve, and ensure that the medium flows in the predetermined direction.

**Flange gasket: sealing guarantee at pipeline connections**

Unlike valve sealing rings, flange gaskets are mainly used between two flange connection surfaces. In pipeline systems, flange connection is a common detachable connection method, and flange gasket is a thin sheet-like sealing element filled between the joint surfaces of two flanges. Its function is to undergo elastic deformation under the pre tightening force of bolts, fill the micro unevenness of the flange surface, and prevent the pressure medium inside the pipeline from leaking out from the connection.

As a professional sealing solution provider, our company has been supplying various high-quality valve sealing rings and flange gasket products for a long time, supporting non-standard customization and material selection consultation.
