High quality Check Valve

The check valve, also known as a one-way valve, a reverse flow valve or a non-return valve, is an automatic valve used to prevent the medium from flowing back in a pipeline.
Its main function is to automatically open or close the valve by utilizing the force generated by the flow of the medium , to ensure that the fluid can only flow in one direction, thereby protecting the safety of the pipeline system and equipment.

WESDUN Products Applications

In water supply, its low flow resistance enables smooth water passage,reducing energy consumption. For example, in large urban water networks, it controlsflow at key points and is used in wastewater treatment plants, where its media -handling and sealing properties prevent leaks for normal operation.​

In power generation, especially in thermal plant steam pipelines, gatevalves are vital. Their ability to handle high – temp, high – pressure steam andeasy operation efficiently control steam flow, ensuring turbine stability.​

In Oil and Gas. In oil pipelines, they regulatecrude oil flow, and their bidirectional flow suits various layouts. In gaspipelines, their good sealing minimizes leakage for safe, efficient transport.​

In chemical Industry. WESDUN products are selected for their chemical resistance and reliable performance. Theycontrol the flow of acids, alkalis, and solvents, facilitating production. Overall,the gate valve’s versatility makes it essential in many industrial systems.
