Product advantages

1.The structure is compact, the valve rigidity is good, the channel is smooth, the flow resistance is small, and the sealing surface adopts a high-hardness wear-resistant plane, which has high strength and good impact resistance. Long service life, using Y-shaped packing, reliable sealing, easy and flexible operation.

2. The installation is fast, simple, safe, reliable, not limited by the installation site, convenient for the maintenance of pipelines and valves, with vibration isolation and sound insulation, and within a certain angle range, it can overcome the imitation difference caused by the misalignment of the pipeline connection, and solve the problem of temperature difference Produce thermal expansion and contraction and other characteristics.

3. It has obvious advantages such as light switch, reliable sealing, good elastic memory and long service life.

4. The hand wheel of the gate valve is manually operated, the valve stem lifts (rising stem) gate, and the material of the valve body is WCB. A set of special valves are installed at intervals in the pipeline to facilitate disassembly, replacement and subsequent maintenance of the pipeline system, and to protect the liquid in the pipeline. The pressure rating and diameter of the valve are matched with the pipeline, and the inner diameter of the valve is not smaller than the inner diameter of the pipeline.

5. In order to ensure the safety and reliability of the work, the gate valve has an integral structure, no welding, manual adjustment, corrosion-resistant surface treatment and good sealing performance. At least two tightness tests are done before leaving the factory to ensure the reliability of the seal.
