Use of slab gate valve
The slab gate valve is a type of sliding valve that uses a parallel ram as its closing element. This element can be either a single plate or a dual-plate design, with a mechanism in between to prevent interference during operation. The design ensures a tight seal and reliable performance under various conditions.
One key feature of the slab gate valve is the way it controls the sealing force between the disc and the seat. This force is influenced by the pressure of the medium acting on a floating or spring-loaded seat. In the case of a double-gate slab gate valve, the expansion mechanism between the two gates helps enhance the sealing force, ensuring better performance in high-pressure applications.
Slab gate valves are widely used in industries such as natural gas, oil, petrochemicals, environmental protection, urban infrastructure, and steam systems. They serve as essential shut-off devices in pipelines, venting systems, and storage facilities. The Z43 series single-plate slab gate valve, which includes diversion holes, is particularly suitable for long-distance natural gas extraction and purification pipelines.
The diameter range of slab gate valves typically spans from DN25 to DN1200, while the pressure range covers 0.6MPa to 45MPa (equivalent to 150Lb to 3000Lb). For pipelines that require ball cleaning, a drain plate version of the slab gate valve is available. On the other hand, models without diversion holes are ideal for applications where ball cleaning is not necessary.
These valves are known for their durability, ease of maintenance, and ability to handle extreme operating conditions. Whether you're working in a high-pressure environment or need a reliable shut-off solution, slab gate valves offer an efficient and cost-effective option.
