1. The valve body has two kinds of structure: casting and welding. The short type plate gate valve without diversion hole adopts welding structure, short structure length, light weight, especially suitable for the device requiring light weight.

2. Floating seat structure, so that the inlet and outlet of the valve can be sealed in both directions.

3. The seat seal is double seal, with double seal function, PTFE can eliminate sand impurities and dirt, ensure good seal.

4. The sealing surface of the valve with hard seal structure is surfaced with cobalt-based hard alloy, and the hardness reaches HRC42-55 to ensure the reliability of the seal.

5. Valve with diversion hole structure, whether fully open or fully closed state, the gate and seat always contact each other, sealing surface is not directly washed by the medium, thus extending the service life.

6. The fire resistance design of valves complies with API 6Fa and API 607 standards, corresponding to valves used in hydrocarbon flow liquids and oil and gas pipelines, which can meet the fire resistance requirements.

7. When the valve is fully open, the channel is straight pipeline, the flow resistance series and pressure loss are very small, and the pipeline can be cleaned by ball.

8. The valve is equipped with automatic pressure relief protection device to ensure safe operation.

9. Fully closed structure, good protective performance, can be used all weather.
