1. Single slab gate valve adopts flat single gate and floating seat structure, suitable for oil & gas gathering and transmission, pipeline medium transportation.
2. The valve is designed in accordance with API 6D and ASME B16.34 standards, with valve cavity pressure relief function.
3. The body, gate and seat can be hardened, and internal parts can be selected according to medium working conditions.
4. It is mainly used in oil and gas transmission pipelines for full open and full shut-off of pipelines, not suitable for throttling service.
1. Flat gate with floating seat. The medium pressure automatically compresses the seat for reliable bidirectional sealing performance.
2. Equipped with valve cavity pressure relief port. It releases abnormal pressure rise inside the cavity when the valve is closed to protect the valve body and sealing components.
3. Hardfaced stellite overlay on sealing surfaces of gate and seat, featuring erosion resistance, wear resistance and long service life.
4. Bottom mounted anti-blowout stem structure for safe and reliable operation.
5. Full bore flow passage allowing pipeline pig to pass smoothly for pigging service.
6. Grease injection valve is optional for on-site supplementary lubrication of seat sealing surfaces.
